▼ Maternal nutrient intake and partitioning, uteroplacental blood flow, nutrient transporter activity, and fetoplacental metabolism mediate nutrient delivery to the fetus. Inadequate delivery of nutrients results in intrauterine growth restriction (IUGR), a leading cause of neonatal morbidity and mortality. The present studies exploited natural population variance in nutrient-restricted (NR) ewes to identify subpopulations of IUGR and non-IUGR fetuses as subjects for research to elucidate adaptive mechanisms of fetal-placental development. Singleton pregnancies were generated by embryo transfer and assigned to receive either 50% (n=24) or 100% (n=7) of the National Research Council’s (NRC) recommended dietary intake from Day 35 to Day 125 of gestation, at which time ewes were necropsied. Maternal weight did not correlate with fetal weight; therefore, differences in development of the six heaviest (NR non-IUGR) and six lightest (NR IUGR) fetuses from NR ewes, as well as the seven fetuses from control ewes were compared. Mean weights of NR IUGR fetuses (2.8±0.1 kg) were lower (P<0.05) than for control (4.0±0.1 kg) and NR non-IUGR (4.1±0.1 kg) fetuses. The first study investigated potential mechanisms regulating nutrient availability for fetuses. Results indicated that normal fetal growth in a subpopulation of NR ewes is associated with enhanced delivery of a number of amino acids and their metabolites into the fetal circulation, which may at least partially result from up-regulation of expression of amino acid transporter mRNAs in the placentome. The second study elucidated potential physiological mechanisms regulating placental growth and development in ewes having NR IUGR and NR non-IUGR fetuses. Results suggest that placentome morphology and angiogenic growth factor expression varies in response to maternal nutritional challenge during pregnancy and may play critical roles in regulating fetal growth. The third study was conducted to capitalize on natural population variance in NR ewes to identify novel factors regulating placental growth and function. Results suggest that enhanced fetal growth in NR non-IUGR pregnancies is associated with an altered expression of genes related to immune response and function in the placentome. Collectively, results of these studies suggest that enhanced fetal growth in a subset of NR ewes is associated with enhanced expression of select nutrient transporters and angiogenic factors, increased nutrient availability to the fetus, altered placentome morphology, and an altered immune response within the placentomes of those ewes.

▼ Primiparous Angus-cross cows (n = 38) were synchronized using a Co-Synch+CIDR protocol and inseminated with semen from one of two Angus sires. Animals were fed at 1.3 x (Control [CON]) or 0.55 x (Nutrient Restricted [NR]) of maintenance energy and protein requirements based on BW (NRC 2000). Diets were fed at either 1.3 x (Control [CON]) or 0.55 x (Nutrient restricted [NR]) of maintenance energy and crude protein values based on BW (NRC 1996). A subset of animals (n = 16) was fed either NR (n = 8) or C (n = 8) from d 30-110 of gestation. The remaining animals (n = 22) were fed CON (n = 8) d 30-190; NR (n = 7) d 30-110 followed by CON d 110-190; or CON (n = 7) d 30-110 followed by NR d 110-190. Cows were slaughtered on d 110 or d 190 of gestation, when fetal measurements and samples were taken for analysis. Fetal weights and empty fetal weights were also reduced (P = 0.0027, P = 0.0023, respectively) in d 110 NR animals. Fetal weights tended to be reduced (P = 0.07) in NR/CON and CON/NR versus CON/CON cattle. Empty fetal weights were reduced (P = 0.03) in NR/CON and CON/NR versus CON/CON cattle. Abdominal and thoracic circumferences were reduced (P = 0.0265, P = 0.0002, respectively) in d 110 NR animals and were also reduced (P = 0.01 and P = 0.03, respectively) in NR/CON and CON/NR versus CON/CON cattle. Brain weight as a percent of empty fetal weight (P < 0.01) was increased in d 110 NR animals compared with d 110 CON animals. Brain weight as a percent of empty fetal weight was increased (P < 0.001) in NR/CON and CON/NR versus CON/CON cattle. Fetal pancreas weight as a percent of empty fetal weight was reduced (P = 0.06) in NR d 110 cattle. Fetal pancreas weight as a percent of empty fetal weight was reduced (P = 0.04) in CON/NR versus CON/CON cattle (0.062 Â± 0.004 versus. 0.079 Â± 0.004 %) while NR/CON values (0.069 Â± 0.004 %) were intermediate. Fetal perirenal adipose as a percent of empty fetal weight was increased (P = 0.01) in NR d 110 female fetuses. Fetal perirenal adipose as a percent of empty fetal weight was increased (P = 0.003) in NR/CON and CON/NR versus CON/CON cattle. The data show that maternal nutrient restriction during early or mid gestation causes asymmetrical fetal growth restriction, regardless if the restriction is preceded or followed by a period of non-restriction. RNA was isolated from flash frozen cotyledon samples (3 subsamples/treatment) using the mirVana microRNA Isolation kit and analyzed using a previously validated microarray. MicroRNA expression was analyzed as an ANOVA analysis using appropriate procedures correcting for false discovery rate of microarray data. Of the sequences chosen for microarray, 88 showed significant (P < 0.05) differential expression between d 190 treatment groups. A total of 40 miRNAs were upregulated in the control group compared with both nutrient restricted groups and a total of 26 miRNAs were upregulated in the nutrient restricted groups compared with the control group. In d 110 animals, 142 showed significant (P < 0.05) differential expression between… Advisors/Committee Members: Long, Nathan M, Hill, Gary M, Strickland, James R, Pratt, Scott L.

▼ The objective of this study was to determine the effect of dam nutrient restriction on offspring carcass characteristics, retail cut yields, and nutrient composition. Forty one western white rams and ewes were obtained from a previous Colorado State University study of dam nutrient restriction. Prior to gestation, dams were fed 100% of their nutrient requirements. The diet of dams was a vitamin-mineral rich pelleted beet-pulp (77.8% total digestible nutrients [TDN], 90.0% dry matter [DM], and 9.4% crude protein [CP]). At 28 days gestational age, dams were randomly assigned to individual pens and separated into three different treatments: control (100% nutrient requirements), half ration (fed 50% of their nutrient requirements from day 28 until term), and realimented (fed 50% of their nutrient requirements from day 28 until day 78, and then slowly realimented back to 100% for the remainder of gestation). All twin lambs were slaughtered, and hot carcass weight, 12th rib fat, body wall thickness, adjusted fat, ribeye area, ribeye marbling, leg score, leg circumference, conformation, flank streaking, flank firmness, flank color, kidney fat weight, L*, a*, and b* were obtained. After all lambs were slaughtered, one half of each lamb carcass was fabricated in the following subprimals: rack, roast ready, frenched PSO 3x1" (IMPS 204C); shoulder, square-cut, boneless (IMPS 208); Denver ribs, skirt-off (IMPS 209A); Foreshank (IMPS 210); loin, short-cut, trimmed PSO 0x0" (IMPS 232A); flank untrimmed (IMPS 232E); leg, hindshank (IMPS 233F); and leg, shank-off, boneless (IMPS 234A). Lastly, all lambs were utilized to determine dry matter, moisture, crude protein, crude fat, ash, vitamins A and E, trace minerals, and fatty acids. No interactions were found between treatment and gender for any characteristic, so treatment and gender were analyzed separately. Lambs of ewes that were nutritionally restricted were smaller in size with less fat. Lambs of the realimented group had more fat than either the control or the half ration groups. Rams had more percent lean content than ewes, which was to be expected. Results of this study provide insight on the effect of nutrient restriction on lamb growth and development, as well as nutrient content of American lamb.

▼ The goal of this study was to investigate feedlot performance and meat quality of calves born to cows that underwent a nutrient restriction during the second trimester of gestation which may be occurring in the Intermountain West. Thirty-four angus influenced calves from the same sire were used for this study. The calves were born from cows that were separated into either a maintenance group, and kept on an irrigated pasture, or a restricted group, that was placed on an unirrigated pasture and allowed to lose one body condition score during the second trimester of pregnancy. This study begins with the calves on day 85 of the finishing portion of the feedlot phase. During the finishing feedlot phase, calves were individually housed, fed ad libitum, and feedlot performance measurements were taken every 28 days. Carcasses from the calves were evaluated for yield and quality. A loin from each carcass was collected, aged, frozen, and cut into individually packaged steaks that were used to assess meat quality. There was no difference in feedlot performance and carcass measurements for either maintenance and restricted calves. Meat quality measurements revealed no difference in color, instrumental tenderness values, or composition of steaks from either group. A trained sensory panel found that ten characteristics of flavor were similar for both treatments. There was however, a trend for steaks from nutrient restricted cattle to have more of a bloody/serumy flavor. The trained sensory panel also found that there was a difference in tenderness of steaks from nutrient restricted animals being perceived as more tender than animals from maintenance cows. The results of this study demonstrate that nutrient restriction during mid-gestation does not have negative effects on feedlot performance, carcass characteristics, or meat quality measurements. These results also indicate that steaks from calves born to nutrient restricted cows may be perceived as more tender. Advisors/Committee Members: Jerrad F. Legako, Kara J. Thornton, Chuck E.

▼ Intrauterine growth restriction (IUGR) is a pregnancy condition where fetal growth is suboptimal, resulting in an infant born small for gestational age (<10th percentile) and is associated with metabolic disorders such as type 2 diabetes in adulthood. This study aims to understand tissue-specific adaptations to fetal undernutrition which predispose the individual to metabolic disorders in adulthood. A model of growth restriction in mice was established using 70% of maternal ad libitum total food (g) (E6.5-birth). At weaning, male offspring received standard chow or a HFHS diet. Body weight and random blood glucose levels were measured at 6 months. To assess metabolism at 6 or 7 months, glucose tolerance, pyruvate challenge and hepatic portal vein insulin challenge tests were administered and serum peptide markers for obesity and diabetes were measured. Metabolic cages were also used at 2 and 7 months to measure activity, food intake and respiratory exchange ratios (RERs). Adult liver, adipose and skeletal muscle and fetal liver was collected for RNA sequencing. Maternal nutrient restricted (MNR) offspring were growth restricted with disproportionately smaller fetal livers. 19% of standard chow-fed MNR offspring became glucose intolerant. On an isocaloric high-fat high-sugar diet no differences in MNR growth or glucose metabolism were detected. However, RERs were reduced at all timepoints in MNR on a HFHS relative to MNR on standard chow. Differences in transcription of genes involved in hypoxia signalling were detected and HIF-2a and HIF-3a proteins were increased in fetal liver of MNR offspring. Genes differentially expressed in the fetus were not differentially expressed at 6 months. Gene expression of metabolically regulatory transcripts in liver, adipose and skeletal muscle did not differ in all MNR and glucose intolerant MNR relative to controls. This model results in a susceptible and non-susceptible population of maternal nutrient restricted offspring and supports the concept of hypoxia signalling contributing to fetal adaptations. Understanding adaptations in hepatic hypoxia signalling in response to fetal undernutrition and how they vary in susceptible and unsusceptible populations will provide insight into how fetal nutrition can influence adult metabolism.

▼ Galactopoietic effects of somatotropin are the result of IGF-I and require high-quality nutrient intake. This study investigated short-term partitioning effects during recombinant bovine somatotropin (bST) administration in high yielding early lactation dairy cows. Administration of recombinant bST has been shown generally to alter results of metabolic tests in the face of unchanged basal glucose and insulin concentrations. Ten multiparous Holstein cows were subjected to rbST (Lactotropin®) and/or feed intake restriction to 80% of predicted ME requirement (80% ME). Responses to insulin challenge (0.1 IU porcine insulin/kg BW. 210 min) and hyperglycaemic clamp (+50 mg/dL whole blood, 120 min) were tested during weeks 8 (control), 9 (rbST ), 11 (80% ME) and 12 (rbST + 80% ME) postpartum. Plasma and whole blood samples were assayed for glucose concentrations. The rbST treatment decreased fasting whole-blood glucose concentration by 9.4% (P<0.0001), which was likely a remnant of control hyperglycaemia. Maximum glucose response was 4.0 mg/dL (21.7%) lower (P<0.0038) and took 6.5 minutes longer to attain (P<0.0037). Steady-state glucose infusion rate (SSGIR) decreased by 8.1 % (P<0.0001). The 80% ME treatment decreased glucose availability by 5 to 6% (P<0.0100), while no glucose responses were affected. Restricted energy intake during treatment with rbST resulted in plasma glucose increase by 5.5% (P<0.0001). Peripheral uptake and utilization of glucose increased by 5.1 % (P<0.0005). Compared to energy restriction, 80%ME + rbST did not alter effects of nutrient restriction on responses to exogenous insulin challenge. Effects were small and inconsistent. SSGIR decreased by 5.0% in the 80% ME + rbST compared to the 80% ME period (P<0.0004) and the change in the hyperglycaemic clamp in the absence of an effect in the insulin challenge may be due to differences in endogenous insulin secretion. The conclusion was that rbST treatment resulted in altered glucose metabolic responses, even with restricted energy intake. Advisors/Committee Members: Prof N H Casey (advisor).

▼ Implant strategy and nutrient restriction prior to finishing may alter feedlot performance, as well as carcass characteristics and consumer acceptability of beef. The objectives of these studies were to determine the effect of prefinishing implant strategy and plane of nutrition on prefinishing and feedlot performance, carcass characteristics and quality, and consumer acceptability of beef. In 2 experiments, spring-born calves were weaned in the fall (Exp. 1, n =120; and Exp. 2, n = 96) and were either finished as calves (CALF-FED) or placed on a growing program with a target ADG of 0.45 kg/d (RSTR) or 0.91 kg/d (UNRSTR) before finishing. Half of each backgrounding group received moderate potency combination hormonal implants (Synovex-S/H; Pfizer Animal Health, Madison, NJ) before finishing (IMPL). At arrival to the feedyard all cattle were implanted with a moderate potency implant and were reimplanted following 100-d (CALF-FED) or 81-d on feed (UNRSTR and RSTR). Animal performance and carcass characteristics data were analyzed as a split plot design using the Mixed procedure of SAS. Treatment least-squares means were separated using predicted differences. Implantation prefinishing positively affected (P < 0.01) ADG in UNRSTR cattle in the feedlot in Exp. 1, and in all growth treatment groups (P < 0.01) in Exp. 2. Cattle in the UNRSTR treatment had greater (P < 0.01) HCW than CALF-FED or RSTR in both experiments, but there was no effect (P = 0.38) of implant on HCW. Cattle fed as calves had a greater (P = 0.02) marbling score than yearlings in Exp. 1, but there were no differences (P = 0.32) in marbling scores across treatments in Exp. 2. In Exp 1, IMPL cattle tended (P = 0.06) to have a lower marbling score and had reduced (P = 0.03) percentage of cattle grading Choice; however, there was no effect (P ≥ 0.32) of implant strategy on the percentage of cattle grading Choice or on marbling score. Cattle receiving an implant prefinishing had less (P ≤ 0.03) initial and sustained tenderness than cattle that received a delayed implant in Exp 1 and 2. Advisors/Committee Members: Paul A. Beck, Richard R. Reuter, Jason K. Apple.

▼ In recent years, a variety of muscle myopathies, specifically wooden breast, white striping, and deep pectoralis myopathy, have severely impacted the poultry industry. Although broilers have become more efficient at producing muscle mass, the rapid increase in growth has exceeded the structural limits of the muscle. As a result, myopathies such as wooden breast are commonly associated with fast-growing, heavy weight broilers. However, there is little genetic correlation with breast muscle yield, indicating that environmental factors likely play a vital role. Environmental factors such as nutrient restriction and thermal stress can alter satellite cell populations, which are a type of stem cell responsible for all post-hatch muscle growth. Changes in the satellite cells will have long-lasting impacts on muscle development and meat quality. Although there have been studies that have elucidated the independent effects of nutrient restriction and thermal stress, there is little information regarding the effect of a simultaneous temperature and nutritional restriction on satellite cells, specifically, immediately after hatch, when satellite cells are the most susceptible to environmental stressors. Since chicks are rarely exposed to a single stressor, it is important to understand how simultaneous environmental factors will impact long-term muscle growth. The effect of a simultaneous post-hatch feed restriction and thermal stress on skeletal muscle growth and meat quality was studied by applying a 20% feed restriction during the first week post-hatch. At the time of hatch broiler chicks were divided into either a 20% feed restriction group, or given ad libitum access to feed and held at an ambient temperature of 31°C, 35°C, or 39°C. Gene expression for satellite cell genes Paired Box Protein 7 (PAX7), Myogenic Factor 5 (MYF5), Myogenic Differentiation 1 (MYOD1), and Myogenin (MYOG), were measured at d 7, and no significant differences were detected (P > 0.25). Muscle fiber diameter, number, and histological scoring were also evaluated and there were no statistical differences observed (P > 0.20). There was also no statistical difference across treatments in meat quality characteristics or meat yield at d 42 (P > 0.05). Feed efficiency and body weight were also recorded from d 0 to d 42 of the trial. Although there was no difference in feed efficiency by the end of the trial, there were significant differences in broiler body weight from d 2 – d 28. Between d 0 – d 7 broilers held at any of the three ambient temperatures had significantly different body weights, with those held at a control temperature of 35°C having the heaviest weights, regardless of nutrient restriction. Birds given a 20% feed restriction had significantly lighter body weights between d 2 – d 28 compared to birds provided ad libitum access to feed regardless of environmental temperature. On d 2, d 3 and d 4, there was a significant interaction between both nutrient restriction and ambient temperature (P < 0.01). However, by the end of the trial d 42,… Advisors/Committee Members: Clark, Daniel (Advisor).

▼ Galactopoietic effects of somatotropin are the result of IGF-I and require high-quality nutrient intake. This study investigated short-term partitioning effects during recombinant bovine somatotropin (bST) administration in high yielding early lactation dairy cows. Administration of recombinant bST has been shown generally to alter results of metabolic tests in the face of unchanged basal glucose and insulin concentrations. Ten multiparous Holstein cows were subjected to rbST (Lactotropin®) and/or feed intake restriction to 80% of predicted ME requirement (80% ME). Responses to insulin challenge (0.1 IU porcine insulin/kg BW. 210 min) and hyperglycaemic clamp (+50 mg/dL whole blood, 120 min) were tested during weeks 8 (control), 9 (rbST ), 11 (80% ME) and 12 (rbST + 80% ME) postpartum. Plasma and whole blood samples were assayed for glucose concentrations. The rbST treatment decreased fasting whole-blood glucose concentration by 9.4% (P<0.0001), which was likely a remnant of control hyperglycaemia. Maximum glucose response was 4.0 mg/dL (21.7%) lower (P<0.0038) and took 6.5 minutes longer to attain (P<0.0037). Steady-state glucose infusion rate (SSGIR) decreased by 8.1 % (P<0.0001). The 80% ME treatment decreased glucose availability by 5 to 6% (P<0.0100), while no glucose responses were affected. Restricted energy intake during treatment with rbST resulted in plasma glucose increase by 5.5% (P<0.0001). Peripheral uptake and utilization of glucose increased by 5.1 % (P<0.0005). Compared to energy restriction, 80%ME + rbST did not alter effects of nutrient restriction on responses to exogenous insulin challenge. Effects were small and inconsistent. SSGIR decreased by 5.0% in the 80% ME + rbST compared to the 80% ME period (P<0.0004) and the change in the hyperglycaemic clamp in the absence of an effect in the insulin challenge may be due to differences in endogenous insulin secretion. The conclusion was that rbST treatment resulted in altered glucose metabolic responses, even with restricted energy intake. Advisors/Committee Members: Casey, N.H. (Norman Henry) (advisor).

▼ A study was conducted to evaluate late gestation maternal nutrient restriction with or without protein supplementation on endocrine regulation in newborn beef calves. This study utilized multiparous cows (4 and 5 yr of age, n = 57) randomly assigned to one of three treatments for the last 100 d of gestation. The control (n = 19) cows were fed to increase BCS while the nutrient restricted (NR, n = 19) and nutrient restricted with protein supplement (NRS, n = 19) cows were fed to lose 1.2 Â± 0.2 BCS during the last 100 d of gestation. Control cows were allowed ad libitum access to tall fescue/crabgrass paddock and when grazing became insufficient, ad libitum hay was provided along with 1.3 kg of corn gluten feed 5 d/wk. Tall fescue paddocks were strip grazed to limit forage availability for NR and NRS. The NRS treatment were individually penned and fed 0.45 kg of soybean meal 3 d/wk. As forage became dormant the nutrient restricted paddocks received limited fescue hay. After parturition cow/calf pairs were moved to one common pasture and received ad libitum silage and 1.8 kg of high concentrate feed. Maternal nutrient restriction regardless of supplementation reduced cow plasma glucose and insulin concentrations during late gestation (P < 0.0001 and P = 0.0051 respectively). Calves from NR dams weighed less at parturition and the NRS calves were intermediate to control calves (33.4 Â± 1.2, 35.0 Â± 1.3 and 37.2 Â± 1.3 kg respectively; P = 0.04,). Plasma glucose concentrations of unsuckled calves at parturition was reduced (P = 0.037) in NR and NRS calves compared to control (67.7 Â± 6.5, 60.1 Â± 6.9 and 83.7 Â± 6.1 mg/dl respectively). At parturition, control and NRS calves had increased (P = 0.0037) plasma leptin concentrations compared to NR calves while calf plasma cortisol concentrations were greater for the nutrient restricted groups than the control (trt x day P = 0.0135). This research demonstrates that late gestation nutrient restriction reduces postnatal calf birth weight, plasma glucose and leads to reduced plasma leptin. Maternal protein supplementation appears to alleviate effects of late gestation nutrient restriction. This research demonstrates that maternal protein supplementation during late gestation nutrient restriction may alleviate effects of late gestation nutrient restriction.
