▼ The International Health Organization (WHO) has recommended that avoid ingestion of processed foods that are high in sodium and add sodium as little as possible to foods in order to reduce early death from cardiovascular disease, however, the average sodium intake is still above the recommended level. The reason is thought to be not only the real difficulty of the eating habits but also the lack of understanding about the influence factors of sodium intake. This study investigated the relationship of total calorie intake on sodium intake among nutritional factors. It is a secondary data analysis study through the nutrition survey of the National Health and Nutrition Survey. Sodium intake was used as a dependent variable and a hierarchical linear regression analysis was performed using statistically the factors influencing sodium ingestion (sex, age, body mass index, infectious disease) and total calorie intake as independent variables. The total caloric intake corresponding to the sodium 2300mg was estimated through the ROC curve analysis. In conclusion, the total calorie intake was quantitatively correlated with sodium intake, and the total calorie intake exceeding the sodium recommended level was from 1630 Kcal. In addition to the existing recommendations of sodium intake, efforts should be considered to reduce total calorie intake.
국제보건기구는 심혈관질환 조기 사망을 줄이기위한 생활습관계선 권고안에서 나트륨이 많은 가공식품 섭취를 가능한 피하고 음식에 나트륨을 최대한 적게 첨가하도록 하였으나, 여전히 평균 나트륨 섭취량이 권장기준이상이다. 이런 이유는 가공식품 섭취나 외식이 많은 식생활 습관 계선이 현실적으로 어려울 뿐 아니라, 나트륨 섭취 영향인자에 대한 이해 부족으로 생각된다. 본 연구는 나트륨 섭취에 기여하는 영양학적 요인 중에서 총 칼로리 섭취량이 나트륨 섭취량에 주는 영향력을 조사하였다. 국민건강영양조사의 영양조사 통한 2차 자료 분석연구이다. 나트륨 섭취량을 종속변수로 하고, 우선 통계적으로 나트륨 섭취에 영향을 주는 요인(성별, 나이, 체질량지수, 유병질환)을 통제하고, 총 칼로리 섭취량을 독립변수로 하는 위계적 선형회귀분석을 시행하였다. 그리고, ROC curve 를 통해 기준 나트륨 섭취량에 해당하는 기준 총 칼로리 섭취량을 추정하였다. 분석결과 총 칼로리 섭취량은 나트륨 섭취량과 상관 정도가 높았고, 나트륨 권장 기준을 초과하는 총 섭취 칼로리는 1630 Kcal 였다. 나트륨 섭취량을 줄이기 위해 기존 권장 사항 뿐 아니라, 총 칼로리 섭취량을 줄이는 노력을 병행해야 할 것이다.

▼ Four experiments were conducted to evaluate
intake and measures of feed efficiency in beef cattle. In Exp. 1 and 2, measures of feed efficiency were calculated on Angus and SimAngus heifers (Exp.1; n = 623, and Exp. 2; 404); and heifers were classified as either high, medium, or low residual feed
intake (RFI), residual BW gain (RG), residual
intake and BW gain (RIG), and DMI. The objective of these experiments was to determine the relationship between post-weaning feed efficiency and
intake in heifers, and subsequent cow performance, reproduction, and longevity as 2-and 5-yr-old cows. As heifer RFI improved, cow forage DMI was reduced in both 2-and 5-yr old cows (P < 0.01) and resulted in more desirable 2-yr old cow efficiency (P < 0.01). Heifer RFI classification did not affect (P ≥ 0.07) reproductive traits, cow production traits, or herd longevity up to 5 yr of age. Heifer RG classification did not affect (P ≥ 0.08) reproductive traits; cow production traits, cow efficiency, or DMI in 2-yr-old cows. As heifer RIG improved, 2-yr-old cow forage DMI was reduced (P < 0.01) during lactation, resulting in more desirable cow efficiency (P=0.02). Heifer RIG classification did not affect (P ≥ 0.12) reproductive traits; calf birth or weaning BW; cow BW, milk production, 12th rib fat thickness, or BCS in 2-yr old cows. Heifer DMI was highly correlated (P < 0.05) to cow forage
intake as both 2- and 5-yr-old cows. Heifers classified as low DMI were least frequently (P < 0.01) kept as replacements and were youngest (P = 0.04) at first calving. Calves from 2-yr-old cows, classified as high DMI heifers, had the greatest (P < 0.01) birth BW; yet, there were no differences (P=0.60) in weaning BW.
Intake classification had no effect (P ≥ 0.07) on cow BCS, 12th rib fat thickness, or milk production in either 2- or 5-yr-old cows. Cows, classified as low DMI heifers, weighed the least (P = 0.02) and had reduced (P < 0.01) hip heights as both 2- and 5-yr old cows. Cows, classified as low DMI heifers, had reduced (P ≤ 0.01) DMI, improved (P = 0.01) cow efficiency, and a greater percentage of females remaining in the herd at 5 yr of age. These data indicate that females classified as more efficient have reduced cow DMI without compromising production traits and longevity. Heifer DMI is an accurate predictor of cow forage
intake at different biological time points in life. In Exp. 3, measures of feed efficiency were determined in Angus and Simmental X Angus heifers (n=263), and heifers were classified within feed
intake and efficiency groups as described in Exp. 1 and 2. The objective of this experiment was to determine the relationship between measures of heifer feed efficiency and mature cow
intake of forage of divergent quality. At 5 or 6-yr of age, cows were evaluated for voluntary forage
intake of high-quality forage (HQDMI) and poor-quality forage (PQDMI). Heifer RFI classification had no effect on cow production traits; yet, cows classified with the least desirable heifer RFI had the greatest (P ≤ 0.05) HQDMI and PQDMI. Heifer RG…

▼ ABSTRACT: Study One - Our objective was to characterize mature range cows based on
intake and grazing activity. Starting in the early spring of 2013, 4 experiments were conducted. First, mature range cows (n = 137) were fitted with radio frequency identification tags (RFID) and placed in a dry-lot pen equipped with GrowSafe® technology to monitor DMI of alfalfa hay. These data were then used to assign cows a residual feed
intake (RFI) value utilizing the National Research Council (NRC) (1996) model to predict
intake of beef cattle. Cattle with negative and positive RFI were characterized as low-
intake and high-
intake, respectively. In addition, the following data were also recorded: weight (kg), age (mo), days pregnant (d), and body condition score (BCS). Second, 30 mature range cattle were selected from the first trial and fitted with pedometers for 7 d to monitor activity with step counts and estimate distance traveled. Third, mature range cows (n = 25) selected from the first trial were fitted with global position system (GPS) collars, and placed on pinyon-juniper rangeland from 20 June 2014 to 17 September 2014. Forth, mature range cows (n = 28) were fitted with GPS collars, and placed on ponderosa pine rangeland from 17 September 2014 to 15 October 2014. Distance traveled, slope, distance from water, elevation data were collected from both GPS trials. Low-
intake and high-
intake cows consumed 9.3 and 12.2 kg/d, respectively (P < 0.0001). Low-
intake cattle became pregnant sooner (P = 0.002) than high-
intake cattle (average of 16 d sooner). Cattle age (mo) equaled 90 and 98 for low- and high-
intake cows, respectively (P = 0.04). Weight, predicted DMI, and BCS did not differ between groups (P > 0.06). Step counts for low- and high-
intake animals were 5839 and 5383 ± 2089, respectively (P = 0.61), and estimated distance traveled was 4.31 and 5.35 ± 1.66 km d⁻¹ for low- and high-
intake animals, respectively (P = 0.77). Low-
intake cows (6.23 km d⁻¹) traveled farther (P = 0.005) each day than high-
intake cows (5.84 km d⁻¹) on pinyon-juniper rangelands, and high-
intake cows utilized (P = 0.013) steeper slopes. No differences were detected (P ≥ 0.06) for distance traveled, distance from water, and elevation for cows grazing ponderosa pine rangeland). However, low-
intake cattle preferred (P = 0.046) steeper slopes on ponderosa pine rangeland than high-
intake cattle. These results indicate that low-
intake animals may travel farther on some rangelands and rebreed earlier. Study Two - Commercial grade heifers (n = 173) born and raised on the University of Arizona's V bar V Ranch from 2012 to 2014 were fitted with radio frequency identification tags (RFID) and placed in a drylot equipped with Growsafe® technology (8 bunks) for 60 d in 3 groups based on birth year in order to calculate DMI, residual feed
intake (RFI), ADG, G:F, and residual gain (RG). Birth date, birth weight, weaning weight, age at start of trial, initial trial weight, and final trial weights were also recorded. Residual feed
intake scores were utilized to…

▼ High dietary sodium intake is hypothesized to increase food intake (FI), fluid intake and glycemic response. Two short-term randomized repeated-measures studies measured the effects of acute sodium intake on FI, water intake (WI), subjective appetite (SA), thirst, and blood glucose (BG) in young men. Sodium additions were 740 and 1480 mg to a solid food (beans) in Experiment 1; and 500, 1000, 1500 and 2000 mg to a beverage (tomato juice) in Experiment 2. FI and WI were measured at ad libitum pizza meals 120 and 30 min later, respectively. SA, thirst and BG were measured at intervals before and after pizza. Compared with controls, treatments with added-sodium had no effect on dependent measures. In conclusion, acute intake of sodium in a solid or liquid matrix does not increase subjective ratings of appetite or thirst, ad libitum food or water intakes, or blood glucose in healthy young adults.

▼ The main objective of this study was to identify
genes, DNA variants and plasma metabolites associated with residual
feed intake (RFI) in beef cattle. In the first study, a total of
117 SNPs were selected and genotyped in 531 steers at the
University of Alberta. The population was split into a discovery
and validation population and multiple marker association analyses
were performed in the discovery, validation and combined
populations using ASReml. Twenty two SNPs were associated (P
< 0.05) with RFI in the discovery population and 7 (of the
22) were also significant (P < 0.05) in the validation
population. Twenty five SNPs were associated with RFI (P <
0.05) in the pooled population. A gene network analysis indicated
that the biological processes associated with the significant genes
included lipid, glucose, protein and steroid metabolism, growth,
energy utilization, and regulation of DNA transcription and
translation. The second study was an association analysis using the
117 SNPs and indicated that 7 were associated with various carcass
quality traits (p ≤ 0.005) in the same population. A third
association analysis was performed using steers at the University
of Guelph, as the discovery population, to identify blood
metabolites associated with RFI. Blood samples were collected at 3
periods with period 1, 2 and 3 corresponding to week 2, 6 and 9
into the feeding period respectively. Two, ten and three
metabolites were significantly associated with RFI (P <
0.05) in period 1, 2 and 3 and accounted for 36%, 74% and 52% of
the variation respectively. A validation analysis was performed
using steers at the University of Alberta as the validation
population. The results indicated that 3 metabolites were
significantly associated with RFI in both discovery and validation
populations accounting for 32.8% of the variation in the validation
population. A metabolic network analysis indicated that the
biological pathways associated with the metabolites included AMPK
signaling, growth hormone signaling, lipid and energy metabolism
and cholesterol metabolism. The genes, metabolites, biological
networks and the biological pathways help contribute to a better
understanding of the physiological processes influencing RFI and
carcass quality in beef cattle.

▼ Food intake is controlled by the coordinated action of numerous brain regions but a complete understanding of the process remains elusive. The nucleus of the solitary tract (NTS), located in the brainstem dorsal vagal complex (DVC) is the first site for integration of visceral synaptic and hormonal cues that act to inhibit food intake. NTS neurons receive synaptic input from sensory neurons of the vagus nerve that relay signals of gastrointestinal stretch and nutrient content. In response to these signals of ingestion, NTS neurons signal to higher brain centres in the hypothalamus and midbrain to inhibit hunger and promote meal termination. A role for astrocytes in brain circuits controlling food intake has begun to be identified. Hypothalamic astrocyte signalling has been implicated in regulating energy homeostasis. Despite a wealth of evidence showing astrocytes in the NTS/DVC are involved in synaptic integration of vagal signals and control of autonomic physiology, the potential role of these cells in feeding control has not been investigated. We hypothesised that NTS astrocytes, and those in the wider DVC, would be responsive to increases in food intake and, in turn, their activation would act in concert with NTS neurons to drive a corresponding suppression of food intake. To investigate this prospect we used dietary manipulation, immunohistochemistry, selective chemogenetic manipulation of DVC astrocytes, behavioural assays and electrophysiology in mice. The key findings of these studies show that in response to acute nutrient excess and gastric distention NTS astrocytes increase their expression of the cytoskeletal glial fibrillary acidic protein and adopt a more ramified morphology, indicative of activation. We also show that selective activation of Gq-proteincoupled receptor signalling in DVC astrocytes suppresses nocturnal food intake and refeeding after a fast. These studies provide evidence that astrocytes may be integrators and effectors of satiety signals and appropriate feeding responses in the DVC.

▼ Eight cecally cannulated Quarter Horse geldings were utilized in a crossover design with two 28 d periods with a 21 d washout period between. Horses were adapted to dietary treatments from d 1 to 19, dry matter
intake was determined from d 20 to 24, and cecal fluid was collected on d 28. Horses were paired by age and body weight (BW) and randomly assigned to treatment. Treatments consisted of housing horses individually in stalls or group housed in a dry lot pen. Regardless of treatment, all horses were individually fed a pelleted concentrate at 1% BW (as fed) offered twice daily 12 h apart. All horses had ad libitum access to coastal bermudagrass hay. Hay was offered to stalled horses initially at 2% BW (as fed) then adjusted based on 120% of a previous 3 d average of voluntary
intake.
A dual marker system was utilized for estimation of voluntary
intake in all horses using titanium dioxide (TiO2) as the external marker and acid detergent insoluble ash (ADIA) as the internal marker. Cecal samples were collected 4-h after the morning meal and immediately analyzed for pH. Samples were transported to the USDA/ARS laboratory to enumerate total anaerobic bacteria and lactic acid bacteria, and to determine methane and ammonia activity.
Cecal pH was influenced by housing (P = 0.02) with group housed horses having lower cecal pH values when compared to stalled horses (6.52 +/- 0.04 and 6.69 +/- 0.04, respectively). The cecal pH values of this study are similar to other reported values when feeding similar diets (5). Populations of cecal total anaerobic bacteria and lactobacillus were not influenced by housing (P >= 0.21). Treatments did not affect the production of acetate, propionate, or butyrate (P >= 0.15). Additionally, methane and ammonia production were not affected by treatments (P >= 0.17). Forage
intake was greater for group housed horses (P = 0.04) than stalled (8.47 +/- 0.89 kg DM/d and 5.17 +/- 0.89 kg DM/d, respectively). In conclusion, confinement housing did not greatly influence the cecal environment of a horse when similar diets were offered.

▼ The objectives of this study were to evaluate the use of fecal NIRS profiling and the n-alkane labeled supplementation method for the prediction of voluntary
intake in beef cattle for the identification of animals divergent in feed efficiency. Additionally, the use of fecal NIRS profiling technology was evaluated for the prediction of diet characteristics.
To examine the use of fecal NIRS profiling to estimate diet quality and dry matter
intake (DMI), fecal samples and phenotype data were collected from 14 beef cattle trials that utilized Calan-gate feeders (American Calan, Northwood, NH) or electronic GrowSafe™ feedbunks (GrowSafe™ DAQ 4000E; GrowSafe™ system Ltd., Airdire, AB, Canada) to measure individual animal feed
intake.
The coefficient of determination for calibration (R_(c)^(2)) and cross-validation (R_(cv)^(2)) of combined trial equations to predict diet characteristics were least accurate for the prediction of NDF using composite fecal samples (R_(c)^(2) = 0.85; R_(cv)^(2) = 0.82), and most accurate for the prediction of CP using individual-day fecal samples (R_(c)^(2) = 0.94; R_(cv)^(2) = 0.91). For the prediction of DMI, R_(c)^(2) and R_(cv)^(2) ranged from 0.49 and 0.42 for the prediction of average-trial DMI using individual-day fecal samples to 0.76 and 0.73 for the prediction of fecal-collection-period DMI using composite fecal samples. While the values obtained for the prediction of DMI were inferior to those obtained for the prediction of diet quality or digestibility, fecal NIRS prediction equations for DMI were successful in predicting the mean DMI of groups as well as predicting individual-animal DMI for the evaluation of divergent RFI groups.
To evaluate the use of an n-alkane labeled supplement for the prediction of
intake, 24 mid-gestation heifers, previously identified as having divergent postweaning RFI, were fed chopped sorghum hay and an n-alkane labeled supplement, ad libitum in electronic GrowSafe™ feedbunks (GrowSafe™ DAQ 4000E; GrowSafe™ system Ltd., Airdire, AB, Canada). In this study, accurate
intake predictions were not obtained as 6-d forage
intake was overestimated by 73.0% when using C_(31):C_(32) alkane pairs and by 38.9% when using C_(33):C_(32) alkane pairs. However, inaccurate measures of supplement and forage
intake by the GrowSafe™ system, as well as large between-animal variation in supplement
intake, feeding behavior, and digestibility may have greatly influenced the accuracy of these results.
Results from this study indicate that fecal NIRS profiling can be used to predict dietary characteristics and DMI for the identification of animals divergent in feed efficiency. Conversely, the n-alkane labeled supplement technique was inaccurate in predicting forage intakes in this trial.

▼ Previous research has shown that increasing the variety of available foods leads to increased
intake; yet few studies have determined whether increased variety can be used strategically to promote
intake of low-energy-dense foods such as vegetables. The present study tested whether the number of vegetables served at a meal influences vegetable consumption and energy
intake. Once a week for 4 weeks, 66 adults (34 women; 32 men) were served a meal consisting of 600 g pasta (ED 1.57 kcal/g) and 600 g cooked vegetables (mean ED 0.52 kcal/g) using a counterbalanced design. At 3 meals the pasta was served with a single vegetable (broccoli, carrots, or snap peas) and at the other meal 200 g each of the 3 vegetables was served. The results showed that subjects ate significantly more vegetables when served the variety than when served any single type (mean 49±9 g; p=0.038). The increase in vegetable
intake remained significant when the variety condition was compared to each subject’s preferred vegetable (mean 23±7 g; p=0.002). Men consumed significantly less energy at the meal when broccoli or carrots were served than when peas or a variety of vegetables were served (mean 80±17 kcal; p<0.04), but meal energy
intake in women did not vary significantly across conditions. The weight status of the participants did not significantly influence the effect of variety on
intake. The results of this study suggest that increasing the variety of low-energy-dense vegetables served at a meal can be used as a strategy to increase vegetable
intake.

▼ The effort of this research is to assess the defense athletics club nutritional status which is one of the crucial factor for once enhancement in performance. Descriptive survey design was used to conduct this research. Endurance athletes were selected and stratified in to sex and their specific events, finally 50% were selected by simple random sampling from each stratum and three coaches were selected purposively. The data has been gathered mainly using questionnaire, observation, interview and direct measurement. The data has been analyzed using both qualitative and quantitative analysis methods. Accordingly, frequency counts with percentage and direct calculation of the energy
intake and expenditure has been employed to analyze various information of the subjects of the study. The findings of the study revealed that, there is energy imbalance in defense club. Moreover, almost majority of the athletes have greater
intake than expenditure except for only a few athletes. Finally, the recommendations were forwarded based on the major findings.

▼ Gap junctions enable metabolic and electrical coupling of adjacent cells. Connexin 36 (Cx36) is a gap junction protein found predominantly in mammalian neurons. Because Cx36 is expressed in many areas involved in the regulation of food
intake, its role in this was explored. I therefore investigated whether genetic knockout (KO) of Cx36 affects the
intake of various sweet tastants during long-term concurrent feeding with bland chow, and affects
intake of sweet tastants alone during short-term feeding. In addition, I investigated whether a conditioned taste aversion (CTA) would be altered by KO of Cx36. LiCl was injected intraperitoneally (IP) following exposure to a sweet novel tastant. 48 hours later mice were given a two-bottle preference test of tastant vs. water to determine aversive response. Cx36 KO animals consumed less sweet palatable tastants and consumed more bland chow during long-term
intake. Sweet tastant consumption was similarly increased during short-term
intake. This is suggestive of Cx36 being implicated in both reward mediated and homeostatic regulation. A CTA was enhanced by the KO of Cx36, potentially due to its role in the reward system, and/or an effect of hypothalamic endocrine nuclei implicated in the acquisition of a CTA. In summary, Cx36 may be involved in reward system response to sweet palatable food consumption, and the magnitude of aversive response. Cx36 may also be implicated in post-ingestive endocrine food
intake and aversion regulation.

▼ Leucine injections directly into the brain decrease food intake whereas supplementation of this amino acid in a diet has a negligible effect on food intake. We sought to investigate why orally supplemented leucine is ineffective as an anorexigen. We found that mice consuming leucine exhibited increased cFos immunoreactivity in the ARC and PVN of hypothalamus, areas controlling energy balance. However, real time- PCR analysis of the hypothalamic tissue in mice that were exposed to oral leucine showed changes in expression of genes involved in the regulation of energy balance as well as those mediating feeding reward (TMEM18, MC4R, CRH, FTO, SLC6A15, DOR). This suggests that leucine consumption affects activity of not only brain pathways that control calorie intake, but also those that mediate eating for pleasure. Hence the lack of feeding response to leucine supplementation in a diet may stem from the simultaneous action of this amino acid at brain circuit promoting reward and energy homeostasis.

(more)
▼ In the environment in which palatable and highly caloric foods are readily available, eating behavior is oftentimes not dictated by the necessity to replenish lacking energy, but rather by the pleasure of consumption. Centrally acting oxytocin (OT) is known to promote termination of feeding to protect internal milieu by preventing excessive stomach distension, hyperosmolality and ingestion of toxins. Initial evidence suggests that another possible role for OT in mechanisms governing food
intake is to reduce consumption of select palatable tastants. This thesis explores the question whether OT is as an appetite suppressant that reduces feeding reward.
The first set of experiments addresses whether OT affects
intake of (a) all carbohydrates, (b) only sweet carbohydrates or (c) sweet non-carbohydrate saccharin in mice. In those studies, generalized injection of a blood brain barrier penetrant OT receptor antagonist, L-368,899, significantly increased the
intake of sweet (sucrose, glucose, fructose, polycose) and non-sweet (cornstarch) carbohydrates and promoted a trend approaching significance in saccharin consumption. Consumption of carbohydrate-enriched foods led to an increase in OT mRNA levels in the hypothalamus.
The second set of studies identifies the nucleus accumbens core (AcbC), a key component of the reward system, as a site that mediates anorexigenic effects of OT. Rats injected with OT directly in the AcbC showed a decreased
intake of sucrose and saccharin solutions as well as of standard chow. This treatment did not cause taste aversion, hence the outcome was not due to sickness/malaise. The effects of AcbC OT on feeding could be observed only in animals offered a meal in a non-social environment. Once a social setting (devoid of direct antagonistic interactions between individuals) of a meal was introduced, AcbC OT failed to reduce feeding. AcbC levels of OT receptor transcript were affected by exposure to palatable food as well as by food deprivation.
The third and final set of studies shows that aberrant integrity of neuronal circuitry within the neuroendocrine and reward systems due to genetic deletion of connexin 36 (Cx36) gap junctions leads to dysregulation of the OT system’s functioning in the Cx36 KO mouse. This dysregulation is associated with hypersensitivity to aversive properties of foods, reduced interest in feeding for reward (palatable carbohydrates and saccharin) and abnormal ingestion of energy.
Overall, the findings suggest that OT diminishes feeding for reward, particularly the
intake of palatable carbohydrates and saccharin, by acting – at least in part – via the reward system. OT appears to be part of central mechanisms that cross-link homeostasis-driven and palatability-related (i.e., flavor- and macronutrient-specific) termination of consumption.

▼ ABSTRACT
FACTORS INFLUENCING COW PERFORMANCE AND
INTAKE
Two studies were conducted to determine how weaning system, residual feed
intake
(RFI), and residual average daily gain (RADG) affect cow performance and
intake. In Study 1, a
two-year study was conducted using Angus and Simmental X Angus heifers (n=114) to evaluate
how weaning system (early weaning (EW) vs. normal weaning (NW)) affects cow-calf
performance and
intake. All cows with male calves were early weaned at 130 d while cows with
female calves were normal weaned at 200 d. These animals were then evaluated for individual
intake at 60 d, 120 d, 180 d, and 240 d postpartum. Weigh-suckle-weigh (WSW) was used to
determine milk production for the lactating periods. BW, Hip height, body condition score
(BCS, 1-9 scale), and backfat via ultrasound were measured. No differences (P > 0.05) were
noted in the 60 and 120 d postpartum cow measurements, but calf BW did differ (P < 0.05) with
male calves being heaver. At 180 d postpartum cows with their offspring early-weaned had
increased (P < 0.05) BW (18.7 kg), BCS (0.29) and decreased DMI (1.23 kg). At 240 d
postpartum cows that had been early-weaned had an increased (P < 0.05) BW (30.5 kg), BCS
(0.31), and BF (0.22 cm). There were no differences (P > 0.05) in DMI or overall pregnancy
rate. Early weaning can improve cow condition and decrease
intake, allowing for increased
stocking rates. In Study 2, a two-year study was conducted using Angus and Simmental X
Angus heifers (n=114) to determine their residual feed
intake (RFI) and residual average daily
gain (RADG) as yearlings using the GrowSafe® system. These animals were then evaluated for
individual
intake at 60 d postpartum (lactating period) and 240 d postpartum (dry period). The
same measurements were taken as in Study 1. For the lactating period, correlations were: heifer
DMI and cow DMI (0.35), heifer RFI and cow DMI (0.20), heifer RFI and cow BW (-0.08),
iii
heifer RFI and cow hip height (0.02), heifer RFI and milk production (-0.09), heifer RADG and
cow DMI (-0.06), heifer RADG and cow BW (0.21), heifer RADG and cow hip height (0.25),
and heifer RADG and milk production (0.03). For the dry period correlations were: heifer DMI
and cow DMI (0.06), heifer RFI and cow DMI (0.29), heifer RFI and cow BW (0.00), heifer RFI
and cow hip height (-0.09), heifer RADG and cow DMI (-0.10), heifer RADG and cow BW
(0.23), and heifer RADG and cow hip height (0.31). Heifer RFI is correlated with cow
intake
and thus can be used to help predict
intake and efficiency without effecting performance.

▼ ProCROSS (Montbéliarde, Viking Red, Holstein) rotational crossbred cows were compared to Holstein (HO) cows for dry matter intake (DMI), body weight (BW), cow height, body condition score (BCS), production, alternative measures of feed efficiency, income over feed costs (IOFC), and residual feed intake (RFI) from 4 to 150 days in milk (DIM) of first, second, and third lactations. Primiparous and multiparous ProCROSS (n = 63 and n = 43, respectively) and HO (n = 60 and n = 37, respectively) cows calved from September 2014 to June 2017. Cows were fed the same total mixed ration twice daily with refusals weighed once daily, and feed was analyzed for dry matter content, net energy of lactation, and crude protein content. The BW was recorded twice weekly, and height at the withers and the hips was recorded monthly. The BCS was evaluated weekly. Daily production of milk, fat, and protein were estimated from monthly test days using Best Prediction. Measures of efficiency from 4 to 150 DIM were feed conversion efficiency (FCE), defined as fat plus protein production (kg) per kilogram of DMI; ECM/DMI, defined as kilograms of energy-corrected milk (ECM) per kilogram of DMI; net energy of lactation efficiency (NELE), defined as ECM (kg) per megacalorie of net energy of lactation intake; crude protein efficiency (CPE), defined as true protein production (kg) per kilogram of crude protein intake; and DMI/BW, defined as DMI (kg) per kilogram of BW. The IOFC was defined as revenue from fat plus protein production minus feed cost. The RFI from 4 to 150 DIM for each lactation was the residual error remaining from regression of DMI on milk energy output (Mcal), metabolic BW (BW0.75), and change in body energy (Mcal). Primiparous and multiparous cows were analyzed separately. Statistical analysis for primiparous cows included the fixed effects of year of calving and breed group, and the analysis for multiparous cows included the fixed effect of breed group and the repeated effect of cow nested within breed group. Primiparous ProCROSS cows (2,807 kg) had lower mean DMI than HO (2,948 kg) cows from 4 to 150 DIM of first lactation. Mean BW was not different for the ProCROSS (562 kg) and HO (556 kg) cows, but primiparous ProCROSS cows had mean wither height that was 4.0 cm shorter and mean hip height that was 2.0 cm shorter than the means of HO cows. Primiparous ProCROSS (3.46) had higher mean BCS compared to HO cows (3.20). Mean fat plus protein production did not differ for the primiparous ProCROSS and HO cows (331 kg vs. 329 kg, respectively). Primiparous ProCROSS cows had higher means for FCE (+5.5%), ECM/DMI (+4.0%), NELE (+4%), and CPE (+5.2%), but a lower mean DMI/BW (–5.3%), than primiparous HO cows. Primiparous ProCROSS cows (875) also had higher mean IOFC than primiparous HO cows (825). In addition, mean RFI from 4 to 150 DIM was significantly lower (more desirable) for primiparous ProCROSS cows than HO cows. Multiparous ProCROSS cows (3,360 kg) also had lower mean DMI than HO cows (3,592 kg) and did not differ (636 kg) from HO…

▼ Les glucocorticoïdes (GC) sont des substances très utilisées en thérapeutique, mais parfois détournées de leur utilisation première par les sportifs en raison de leurs effets ergogéniques. Si les effets secondaires d’une prise chronique de GC sont bien connus, les répercussions d’un traitement court restent controversées. Nous nous sommes tout d’abord intéressés aux effets d’un traitement d’1 semaine de GC (50-60 mg/j de prednisone/prednisolone) sur la prise alimentaire, la composition corporelle, la glycémie, l’insulinémie et la sécrétion d’adipokines chez des sujets masculins et féminins sportifs de loisir. Pour des raisons éthiques, cette étude n’a pu être conduite chez des sportifs de haut-niveau. Les adipokines (i.e., leptine et adiponectine) apparaissent significativement augmentées chez tous les sujets par le traitement de GC, mais celui-ci n’entraîne aucune modification de la prise alimentaire, de la composition corporelle ou de l’insulinémie. Il n’existe pas d’effet genre à l’exception de l’hyperglycémie mise en évidence sous GC uniquement chez les sujets de sexe masculin. Il apparait également qu’un traitement d’une semaine de prednisone per os n’altère que de manière très transitoire l’axe hypothalamo-hypophyso-surrénalien, avec un retour à des concentrations basales de cortisol et de DHEA seulement 3 jours après la fin du traitement.
Glucocorticoids (GC) are substances widely used in therapy, but sometimes diverted from their primary use by athletes for their ergogenic effects. Whereas the side effects of chronic use of GC are well known, the impact of short treatment remains controversial. We first investigated the effects of 1 week treatment of GC (50-60 mg/day of prednisone/prednisolone) on food intake, body composition, blood glucose, insulinemia, and adipokine secretion in male and female recreationally-trained athletes. For ethical reasons, this study could not be conducted in elite athletes. The adipokines (ie, leptin and adiponectin) appear significantly increased in all subjects after the GC treatment, but the treatment does not induce any change in food intake, body composition or insulin concentrations. There is no gender effect with the exception of hyperglycemia demonstrated with GC only in males. It also appears that the short-term treatment of oral prednisone alters the hypothalamic-pituitary-adrenal axis only very transient, with a return to basal levels of cortisol and DHEA only 3 days after of treatment.

▼ The impact of RFI selection was investigated using offspring (n=67) from commercial Angus cows mated to Angus (AA) or Braunvieh (BA) bulls with large differences in RFI (high vs low). Following slaughter at predetermined endpoints of 1.4 cm
for AA and 1.0 cm for BA, carcass data were collected and slice shear force was performed. Low RFI cattle gained faster, were heavier at slaughter, and tended to have higher G:F than high RFI. BA cattle were heavier entering the feedlot and spent longer
on feed with lower G:F than AA. Breed nor RFI selection impacted RFI. Carcasses from low RFI sires were heavier with larger REA and lower USDA yield grades. Total primal yield (%) was higher in BA vs AA, low RFI vs high, and steers vs heifers. Findings
suggest that selection using phenotypic RFI in bulls had no effect on RFI in their first generation calves, although certain measures of growth and efficiency were improved.

▼ The short-term effects of exercise on appetite and ad libitum energy intake have received considerable interest as a potential strategy to reduce the prevalence of obesity over the past two decades. The experiments in this thesis have further investigated this topic by examining the appetite and the ad libitum energy intake responses in anticipation of an acute bout of aerobic exercise session. To achieve this, healthy, regularly active males and females (M= 55; F= 34; mean ± SD: age 24± 5 years; BMI 23.4± 3.2kg/m2) were recruited into four studies. The aim of the experiments in this thesis was to focus on the behavioural aspects of appetite and energy intake,and therefore, gut hormone responses were not investigated. In Chapter IV, a hypothetical exercise scenario (i.e. 60 minute hard aerobic exercise session) prompted a ~24% increase in the planned energy intake as opposed to a hypothetical rest scenario in regular exercisers. In Chapter V, we further demonstrated that anticipation of an aerobic exercise session (30 minutes cycling at 75% HR-max; 30 minutes running at 80% HRmax) led to an increase in planned energy intake for breakfast compared to a resting control trial. However, differences in planned energy intake did not result in any differences in the actual ad-libitum energy intake in the post-exercise or rest period. Chapter VI revealed a novel and a reproducible method to measure evening energy intake with a food pack that contained preweighed food items. This method was then employed for the following two chapters to measure evening food intake. Chapter VII investigated the effect of a planned 60 minute late-afternoon aerobic exercise session on appetite and energy intake both before (i.e. at breakfast and lunch) and after (i.e. over the evening) exercise compared to an identical resting control trial. The results indicated that a partial compensation (~11% increase in energy intake at lunch in the exercise trial) takes place during the preceding meal in response to a planned exercise session. However, this increase in energy intake at lunch was not sufficient to offset the energy deficit created by the exercise session, and therefore, still resulted in a negative energy balance (EB) in the short-term. Finally, Chapter VIII showed that this compensatory behaviour is still apparent in the preceding 24 hours and resulted in a ~10% increase in energy intake when compared to a resting control in anticipation of an aerobic exercise session, although this compensatory increase was still not sufficient to offset the energy deficit created by the exercise. Taken together, this thesis has shown that ad-libitum energy intake is affected by the anticipation of an aerobic exercise session. Moreover, although this compensatory increase in energy intake is not sufficient to offset the energy deficit created by the exercise session, it furthers our understanding of the effects of exercise on eating behaviour and the need for an explicit study design to explore the effects of exercise on appetite and energy intake in a…

▼ Objective: Explore the most commonly reported
food choices between breastfeeding (BF) and formula feeding (FF)
mother-infant pairs receiving comprehensive nutrition education
(with an emphasis on dark green and dark yellow vegetables) and
breastfeeding and formula feeding mother-infant pairs receiving
standard nutrition handouts. Subjects: A subset
of four mother-infant pairs (breastfeeding-intervention,
breastfeeding-control, formula feeding-intervention, and formula
feeding-control) were selected from an ongoing study regarding the
eating patterns of infants and mothers (G. Falciglia, PI).
Participants were mothers who were six weeks post-partum, between
the ages of twenty-one and thirty-five, with a Body Mass Index
greater than twenty-five. Each woman’s respective single-birth,
full-term infant comprised the other component of the pairs.
Study Design: Participants were randomly
assigned to either the intervention group (nutrition education
program consisting of four in-person sessions, weekly phone calls,
and dietary monitoring tools) or the control group (standard
nutrition information in the form of two written handouts only).
Methods: Three days of self-reported 24-hour
recalls were collected from mother-child pairs within one week at
time points: baseline (infant age six weeks), infant age six
months, infant age twelve months, and infant age eighteen months.
Nutrition Data System for Research computer software (NDSR) was
used to collect nutrition information. Food amounts consumed were
expressed in grams to allow for discrepancy between adult versus
infant serving sizes. Reported dietary choices were collected as
the specific food and subsequently further categorized into groups
(ex. Dark Green Vegetables, Other Dairy, Rice and Pasta, etc.).
Results: Based on the dietary recalls of the
four previously discussed mother-infant pair case studies, several
patterns of food item selection were observed. With primary
interest to the study’s goal, the frequency of reported target
vegetables consumed appeared to be greater in intervention group
mother-infant pairs versus control group mother-infant pairs.
Additionally, foods introduced at infant age 6 months were also
frequently consumed at infant ages of 12 and 18 months of age. By
the infant age of 12 months, intervention mothers and infants
reported three or more congruent food items per recall time point.
Alternatively, control mothers and infants reported consistently
less similarities of food item consumption. Each observation
demonstrates an important anecdotal trend which may be utilized in
further study of methods of dietary intervention. However,
statistical analysis among a larger population remains necessary in
order to assess for significant differences.
Conclusion: Structured nutrition education
sessions, phone calls, and vegetable monitoring appeared to enhance
participant adherence towards increased vegetable consumption among
intervention group mother-infant pairs. As the primary provider of
nutritional care,…

Maternal and Child Dietary Intake: The Role of Maternal

▼ Background: Obesity is a significant health problem
in preschool children, and is associated with high dietary intake
of fats and added sugars, which displace fruits and vegetables.
Mothers’ dietary intake consistently predicts child intake,
therefore understanding the mechanisms underlying maternal food
choices is crucial. Cognitions about the self as a healthy eater
predict dietary intake in diverse samples but the linkage has not
been investigated in mothers and their feeding behaviors. This
study investigates the relationship between maternal healthy-eating
self-cognitions and maternal and child dietary intake and weight.
Theoretical Framework: This study builds on the self-schema
theory and evidence that a healthy-eater self-schema (HESS)
predicts nutritious dietary intake in adults. Self-schemas are
chronically accessible knowledge structures about the self that are
formed in specific domains and influence information processing and
predict related behaviors. The research hypotheses are: (1)
maternal HESS will be negatively associated with maternal and child
BMI and saturated fat and added sugars, and positively associated
with fruits and vegetables in maternal and child diets, and (2) the
association between maternal HESS and child dietary intake will be
mediated through maternal dietary intake, nutrition knowledge, and
home food availability.
Methods: A cross-sectional, descriptive
design was used with mothers and their 2-5 year old children (N=124
dyads). Block Food Frequency Screeners were used to measure diets
(mother and child) and Kendzierski’s Healthy-Eater Self-Schema
questionnaire was used to measure HESS. Heights and weights were
measured. Multiple regression and multiple mediation analyses were
performed.
Results: Maternal HESS was positively associated with
maternal BMI and intake of fruits and vegetables, and negatively
associated with intake of added sugar. Maternal HESS was not
directly associated with child BMI percentile or child dietary
intake, but was indirectly associated with child intake of fruits,
vegetables, and added sugar through maternal intake of the same
foods.
Implications: Based on the results from the present
study in which a maternal HESS influenced child dietary intake
through maternal dietary intake, developing an intervention focused
on building or enhancing a HESS in mothers could be an efficacious
way to promote healthy dietary intake in mothers and their
preschool-aged children.

▼ The current rates of overweight and obesity indicate that dietary strategies are needed to help individuals moderate energy
intake in an eating environment that encourages overconsumption. Research has shown that dietary approaches such as reductions in food energy density (kcal/g), consumption of pre-portioned entrées, and consumption of satiety-enhancing foods can decrease energy
intake. There are still questions that need to be explored, however, in order to provide effective recommendations for individuals seeking approaches to curb energy consumption. First, reductions in energy density decrease energy
intake, but it is not known if the effects depend on the way that energy density is reduced. Secondly, pre-portioned entrées are commonly consumed to help control portion size and limit energy
intake, yet the influence of their characteristics on energy
intake has not been well studied. Lastly, foods that enhance satiety can reduce overconsumption, but the availability of large portions of energy-dense foods in the current food environment may counter their benefits. Examination of these issues will lead to better dietary strategies to help decrease energy
intake.
The first study examined whether three commonly used methods of reducing energy density (decreasing fat, increasing fruit and vegetables, and adding water) differed in their effects on energy
intake across the day. In a crossover design, 59 adults (29 men and 30 women) consumed breakfast, lunch, and dinner in the laboratory on one day a week for four weeks. Across conditions, the entrées were either standard in energy density or were reduced in energy density by 20% using one of the three methods. Each meal included a manipulated entrée along with unmanipulated side dishes; all foods were consumed ad libitum. It was found that reducing the energy density of entrées significantly decreased daily energy
intake compared to the standard energy density entrées (mean
intake 2667±77 kcal/day; p < 0.0001). The mean decrease was 396±44 kcal/day when fat was reduced, 308±41 kcal/day when fruit and vegetables were increased, and 230±35 kcal/day when water was added. Comparison of the three methods of energy density reduction showed that daily energy
intake was lower when fat was decreased but was not significantly different between increasing fruits and vegetables or adding water.
The second study determined how variations in the energy content and energy density of pre-portioned entrées combine to influence daily energy
intake. In a crossover design, 68 non-dieting adults (28 men and 40 women) were provided with breakfast, lunch, and dinner once a week for four weeks. Each meal included a manipulated pre-portioned entrée that was compulsory, followed by a variety of unmanipulated discretionary foods that were consumed ad libitum. Across conditions, the entrées were varied in both energy content and energy density between a standard level (100%) and a reduced level (64%). The results showed that in men, reductions in the energy content and energy density of…

▼ Research on restrained eating has led to the belief that an eating style that relies on physiological cues of hunger and fullness may enhance dietary outcomes as compared to an eating style that relies on cognitive control. Two types of interventions have been developed to assist with the development of an eating style that relies on cues of physiological need. These interventions focus on mindful eating (ME) and intuitive eating (IE). This systematic review examined how ME and IE interventions influence dietary
intake, and how well the interventions influenced ME and IE by reporting outcomes when they were assessed with a validated tool. The selection of literature followed the PRISMA systematic review process, in which PubMed, CINAHL and PsycINFO databases were searched. Studies were included if they met the following criteria: randomized trial design, in which one arm was an intervention with an ME or IE component and there was at least one other arm that was a control or active comparison; enrolled participants were of a healthy weight or with overweight or obesity and were at least 18 years of age; and outcomes of energy
intake or diet quality were reported at baseline and post-intervention. A total of 14 studies, represented by 15 articles, were included, which were comprised of 9 ME interventions and 5 IE interventions. Eight studies, representing 9 articles, reported on energy
intake, with six studies reporting no significant differences between groups. Twelve studies, representing 13 articles, reported on diet quality, with 7 studies reporting no significant differences between groups. Four studies measured ME and IE with a validated tool, which revealed ME or IE interventions did not consistently increase ME or IE. Overall, evidence suggests that ME and IE interventions do not influence dietary
intake; however, future research using validated tools to measure ME and IE is needed. Without the measurement of ME or IE, it is hard to conclude whether participants adopt the ME and IE approaches, and what effect these interventions have on dietary
intake. PROSPERO registration number: CRD42019128135

▼ Eight hundred and sixty-four crossbred yearling steers were used in a 3 x 4 factorial experiment to study the effects of β - agonist (BA) administration and crude protein (CP) withdrawal during the last 28 d on feed. Three BA treatments were evaluated: no BA, 200 mg Optaflexx (OPT) per head daily for 28 d, and 75 mg Zilmax (ZIL; 7.56 g/ton DM basis) per head daily for 20 d. The 4 CP withdrawal treatments included: 1) 13.5% CP, 3.5% crude protein equivalent (CPE) from non-protein nitrogen (NPN) from d 0 through slaughter (13.5/3.5); 2) 13.5/3.5 until 28 d remained on feed followed by 12.5% CP, 3.5% CPE from NPN (12.5/3.5); 3) 13.5/3.5 until 28 d remained on feed followed by 12.5% CP, 2.5% CPE from NPN (12.5/2.5); and 4) 13.5/3.5 until 28 d remained on feed followed by 11.5% CP, 1.5% CPE from NPN (11.5/1.5). There were no interactions (P > 0.32) between BA and CP withdrawal treatment; therefore, only main effects are discussed. Average slaughter weights and ADG were greater (P < 0.01) for steers treated with BA as compared with control steers. There were no differences between the slaughter weights and ADG for the OPT versus the ZIL steers. Beta-agonist treatment had no effect on daily dry matter
intake. Feed-to-gain ratio was improved by 25% for steers fed BA during the final 28 d as compared with controls. More than a 35% improvement (P < 0.001) in gain-to-feed ratio (G:F) for the final 28 d was observed for steers fed BA as compared with controls. Differences between OPT and ZIL were not significant. Net energy recovery was increased 19% during the final 28 d on feed for steers fed BA as compared with controls. Least squares means for HCW, adjusted for live weight at treatment initiation, was 9.21 kg heavier (P < 0.01) for ZIL steers as compared with controls. The advantage (P < 0.05) in HCW for ZIL as compared with OPT was 5.81 kg. Although not statistically significant, the numerical advantage in HCW for OPT as compared with controls was 3.4 kg. Dressing percentage was increased for steers fed ZIL versus control (64.4 versus 63.4%, P < 0.001) and OPT (P < 0.01) but not increased for OPT versus control (63.2 versus 63.4%; P = 0.67). No BA treatment differences were observed for fat depth measured at the 12th rib. Ribeye area for control carcasses (avg = 32.87 cm2) was lower (P < 0.06) than OPT (avg = 33.53 cm2) which was in turn lower (P < 0.01) than ZIL (avg = 34.59 cm2). Kidney, pelvic, and heart fat was lower for ZIL as compared with control (P < 0.05) or OPT (P < 0.10). Yield grades calculated from carcass measurements were similar for OPT and ZIL (3.01 versus 2.97), and both were reduced (P < 0.05) as compared with control (avg = 3.12). Carcasses from OPT and ZIL treatments were more likely (P < 0.05) to qualify for the USDA Yield Grade 1 and 2 categories and less likely (P < 0.05) to qualify for the USDA Yield Grade 3 category as compared with control. There were no differences in the distribution of USDA Yield Grade 4 and 5 carcasses among control, OPT, and ZIL treatments. Marbling score…

▼ The micronutrient intake of the average South African is not optimal. National fortification of staple foods does not solve all micronutrient deficiencies. Furthermore, urbanisation causes a shift in food intake, increasing the availability of cheaper and more energy dense food and drinks that are often lacking in micronutrients. It is unclear whether the current literature provides sufficient evidence of nutrient dilution by the moderate consumption of alcohol and/or added sugar. The aim of the present study was to evaluate the dietary intakes of a population in nutrition transition and determine the effect of intake of alcohol and added sugars on intakes of micronutrients and food groups to provide information for the development of preventive strategies in public health. A number of countries, including South Africa, suggest limited alcohol and sugar intakes in the Food Based Dietary Guidelines but do not quantify this recommendation.
Data from the "Transition and Health during Urbanisation in South Africa" survey (THUSA) were analysed for dietary intakes (as determined by a validated quantified food frequency questionnaire), age and body mass index (BMI). The THUSA study was conducted during 1996 and 1998 in the North West Province and included 1854 "apparently healthy". Respondents aged 15 years and older from 37 randomly selected sites from rural and urban areas. Alcohol intake (absolute intake and percentage of energy) was the highest for men living in middle class urban areas. With increased urbanisation, the type of beer shifted from sorghum based to commercial beer. Sixty-one percent of men and 25% of women reported that they consumed alcohol at the time of the survey. Eighteen percent of men and 11.7% of women consumed more than 30g and 15g alcohol per day, respectively (intakes which are regarded as moderate). Men and women consuming the most alcohol had significantly higher mean intakes of most macro and micronutrients. However, the intake of vitamin Bi2, B6, folate, vitamin E and vitamin C did not meet the recommended dietary intake (RDA) across all levels of alcohol intake. Although the total energy intake increased with increased alcohol intake, there was no significant difference between the mean BMI of men or women with different levels of intake.
One third of the population consumed more than a 100g of added sugar daily. Intake of sugar was the highest in the farm dwellers but the intake of sweets, cakes, cookies and cold drinks was the highest in the urban areas. As sugar intake increased so did energy, carbohydrates and most micronutrients. However, the intake of vitamin B12, folate, vitamin C and calcium did not meet the RDA across all levels of sugar intake. BMI did not differ between respondents with the highest and lowest sugar intake and no association was found between BMI and sugar intake. The THUSA study was conducted before fortification of staple food became law in October 2003. Maize meal and wheat flour are nowadays fortified with certain vitamins and minerals which may alleviate…

▼ To evaluate the performance of proposed submerged intakes in an early design phase, a performance analysis model able to evaluate a range of
intake geometries is required. This document details how such a model was developed with the use of available sub-models for specific flow features. A formulation of the method of characteristics suitable for rotational flow was used to compute the parts of the flow field not affected by viscous effects. Boundary layers, both laminar and turbulent, were implemented via integral integral relations that provide the growth of the boundary layer. The effects of shock waves interacting with the boundary layers, both in shock wave reflection on the
intake walls and the pressure rise in the shock train, are implemented via experimentally obtained correlations. To investigate the effects that several design variables have on the
intake performance, a parametric study was performed with the
intake analysis model. It confirmed the initial expectation that an increased expansion angle significantly decreases the total pressure recovery, a measure of efficiency, that is achieved by the
intake. Using a gradual compression or multishock compression surface reduces the loss of total pressure due to shock waves. Performance could be further improved by performing further internal contraction via an improved cowl shape.

▼ Developing, Validating, and Improving a 24-hour Web Food Report Questionnaire Jay Robert Desai
Precise and accurate assessment of usual energy and nutrient intake among free living populations remains a major challenge for the study of diet and disease. The food frequency questionnaire (FFQ) carries a relatively low cost and participant burden, but it is much less accurate than multiple 24-hour telephone recalls (24TR). However, 24TRs are usually prohibitively expensive for large studies, and carry a high participant burden. Consequently, there remains a great need for alternative self-report approaches. Emerging web technology and internet penetration provide an opportunity to reduce dietary measurement error while increasing participant and investigator convenience. We developed the 284-item 24-hour Web Food Report Questionnaire (WFRQ) and conducted a pilot comparative validation study (n=51) examining energy and nutrient intake estimates from three WFRQs and the NCI Dietary History Questionnaire (NCI-DHQ) compared to three interviewer-administered 24TRs. Mean intake estimates were similar between the 24TR and the WFRQ but significantly lower with the NCI-DHQ for many nutrients. Correlations with the 24TR ranged from 0.24 to 0.73 and were typically lower with the NCI-DHQ than the WFRQ. Compared to estimated energy requirements the 24TR, WFRQ, and NCI-DHQ under-reported energy intake by 15%, 19%, and 25%, respectively. On average the WFRQ took 10 minutes to complete. A more in depth examination of reported foods and food amounts consumed, comparing 24TRs and WFRQs collected for the same day (n=46), revealed that the 24TR better captures foods used as additions, food-types, and for some foods, portion amounts. Incorporating more food detail and more effective portion size aids may improve the validity of the WFRQ. At the same time, refining the mapping of the WFRQ food items and portion categories to our food and nutrient database may also reduce measurement error. The WFRQ `beta' version is promising for research use in large studies involving free living populations.

▼ Obesity is a growing health concern throughout the world. Health risks associated with obesity such as diabetes and heart disease result in obesity costing us over $170 million annually. Self-monitoring of Energy
Intake (EI) is a critical element of a successful weight loss plan; however current methods to monitor EI are cumbersome and prone to under reporting. The primary purpose of the study was to develop and test an experimental diet protocol based on user feedback from the Bite Counter. A secondary purpose was to examine if this protocol would affect meaningful weight loss by device users. Data were collected from 30 participants (15 control) in a study where Bite Counter feedback was used to titrate daily bite count goals in order to meet a 1 to 2 pound per week weight loss goal measured against the control group which was only given weight loss literature. 77% of our participants were able to use the device to self-monitor a majority of the eating activities. Although weight loss was higher in the Bite Counter group, we determined that a diet protocol based solely on using the Bite Counter did not produce statistically significant weight loss over the ten-week study period. The Bite Counter was able to help the control group sustain their weight loss throughout the entire study period. The study determined that aggressive screening measures during study uptake is needed in order to ensure the recruitment of participants who are likely to complete future studies. User profile personas were developed to assist future researchers identify and classify users as successful or unsuccessful candidates for losing weight using the Bite Counter.

▼ A tese descreve o consumo de alimentos marcadores da qualidade da dieta no Brasil e identifica os alimentos que mais contribuem com a ingestão de açúcar e sódio no país. Foram
utilizados para este fim os dados do Sistema Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL) realizado nos anos de 2007, 2008 e 2009 e os dados provenientes do primeiro Inquérito Nacional de Alimentação (INA) realizado nos anos de 2008-2009 no Brasil. Os resultados são apresentados na forma de quatro artigos. O primeiro artigo avaliou as questões marcadoras de consumo alimentar do Sistema VIGITEL e sua evolução temporal e inclui 135.249 indivíduos de 27 cidades brasileiras, entrevistados nos anos de 2007 2009. Para os demais artigos, utilizou-se os dados obtidos no INA, para descrever os alimentos mais consumidos no país segundo sexo, grupo etário, região e faixa de renda familiar per capita (artigo 2) e identificar os alimentos que mais contribuem para o consumo de sódio (artigo 3) e de açúcar na população brasileira (artigo 4). As análises do INA baseiam-se em informações do primeiro de dois dias não consecutivos de registro alimentar de 34.003 indivíduos com 10 anos ou mais de idade. Os resultados apresentados indicam que a alimentação dos brasileiros vem se caracterizando pela introdução de alimentos processados de alta densidade energética e bebidas com adição de açúcar, embora os hábitos tradicionais de alimentação, como o consumo de arroz e feijão, ainda sejam mantidos. Entre as bebidas açucaradas os refrigerantes aparecem como importante marcador da qualidade da dieta na população brasileira. Os dados do VIGITEL evidenciaram aumento no consumo deste item de 7% e dentre os itens avaliados no inquérito, foi o que mais discriminou o consumo alimentar na população. De acordo com os dados do INA, o refrigerante foi um dos itens mais consumidos pelos brasileiros, e constitui-se também como marcador do consumo de açúcar total, de adição e livre, juntamente com sucos, café e biscoitos doces. Adolescentes apresentaram o maior consumo de açúcar, comparados aos adultos e idosos e este resultado
pode ser explicado pelo alto consumo de bebidas açucaradas e biscoitos doces observado nesta faixa etária. Quanto ao consumo de sódio, alimentos processados, como carne salgada,
carnes processadas, queijos, biscoitos salgados, molhos e condimentos, sanduíches, pizzas e pães figuraram entre as principais fontes de sódio na dieta do brasileiro. Nossos achados
reafirmam a importância de políticas de alimentação e nutrição, que estimulem o consumo de alimentos saudáveis, como frutas, verduras e grãos integrais, e a manutenção do consumo de
alimentos básicos tradicionais, como o feijão. O sistema VIGITEL deve contemplar itens do consumo alimentar que possam ter impacto na redução das doenças crônicas não transmissíveis.

▼ Osteoporosis, a major public health problem, likely has its origins in childhood. During periods of rapid skeletal growth, diet may influence accrual of bone mineral density (BMD) and adult bone health. This study used novel approaches in bone imaging to further characterize optimal skeletal development and enhance our understanding of key dietary components that influence attainment of peak bone mass (PBM) and contribute to determinants of peak bone strength in peri-pubertal females. The use of a validated food-frequency questionnaire (FFQ) enabled the influence of usual dietary
intake on bone parameters to be examined.This study examined the relationship of dietary
intake of micronutrients and bone macro-architectural structure in peri-pubertal girls. This study suggested that vitamin C and zinc
intake are associated with objective measures of bone status in 4th, but not 6th grade girls. This indicates potential differences in micronutrient and bone associations at various age-associated stages of bone maturation.The impact of dietary fat on peri-pubertal skeletal growth is not well characterized. This study examined relationships of select dietary fatty acid (FA) intakes and measures of bone status in peri-pubertal girls. This study suggested that MUFA, total PUFA, n-6 and linoleic acid (LA) are inversely associated with bone status prior to menarche, but composition of dietary fat may be more important during the early-pubertal years. Decreased intakes of n-6 PUFA may benefit bone health in young girls.The impact of a dietary protein on volumetric bone mineral density (vBMD), bone mineral content (BMC) and bone strength throughout maturation remains controversial. Given evidence of both anabolic and catabolic affects of protein on bone health, this study examined relations of dietary protein from different sources with bone parameters in peri-pubertal girls. This study showed that dietary protein
intake is related to higher trabecular but not cortical vBMD, BMC and BSI, and accounts for 2-4% of their variability in peri-pubertal girls. The relationship seems to vary by the source of dietary protein and calcium
intake. However, a negative impact of animal protein on bone health is not supported. Large scale observational and intervention studies are needed to establish causality.

▼ In the first 3 days of life, triplet lambs, especially the smaller triplets, are less capable of surviving than twins and singles. However, whether differences in behaviour and survival of lambs within triplet litters persist after this period is unknown. This trial examined the differences in sucking behaviour and milk
intake between the light, medium and heavy lambs within a triplet litter at 8-17 days of age, with the lamb rank based on birth weight. Of 28 triplet carrying ewes, only 10 complete litters survived to at least 8 days of age and could be used for this trial. After 4 hours of separation, the lambs were returned to the ewe and the behaviour of the lambs and ewe was observed for a period of 15 minutes. The abdominal girth and body weight of the lambs were measured before and after the sucking period. At 8-17 days of age, triplet lambs still differed in terms of weight (P=0.001) and abdominal girth (P=0.002); the triplet lambs born lightest were still lightest and had the smallest abdominal girth. However, there were no statistical relationships between lamb rank and sucking behaviour. Light, medium and heavy lambs did not differ in the number of sucking bouts, number of attempted bouts, total sucking duration, mean sucking bout duration, relative sucking duration, teat fidelity or number of butts. Nor did lamb rank affect the behaviour of the ewes (kicks or butts, walking away from lambs) or measures of milk
intake such as relative weight gain or girth gain. However, there was a tendency for lamb rank to have an effect on one measure of milk
intake (weight gain) (P=0.09). The lambs that were lightest at birth tended to gain less weight during the observation period than heavier lambs, particularly those of medium birth weight. There was also a tendency for lamb rank to have an effect on relative girth gain (P=0.08). The lambs born lightest tended to gain more girth relative to their original girth than the heaviest lambs. The only measure of sucking behaviour that tended to differ with lamb rank was the frequency of teat switching (P=0.09); medium lambs tended to switch teats more often than the heaviest lambs. Overall, weight gain is likely to be the most accurate indicator of milk
intake; based on this variable, lambs born lightest appear to have ingested less milk than their heavier siblings, despite the lack of differences in sucking behaviour. These lambs were still lighter and smaller at 8-17 days of age, suggesting that they had lower growth rates and potentially lower chances of survival. Further research should aim to determine whether ewes and lambs can adapt their sucking behaviour to cope with triplet litters, instead of twins or singles, or whether ewes should be selected for higher milk production. In addition, the effect of different management strategies (e.g. fostering or weaning of the lightest lamb or providing milk supplement) on triplet lambs’ milk
intake, growth and survival should be tested.
