Context: Various body-cooling modalities after exercise or between exercise bouts have been shown to decrease body temperature. The addition of head cooling (HC) to other commonly used cooling modalities may aid in reducing thermal strain. Objective: To determine the efficacy of head cooling on rectal temperature (Tre) compared to commonly implemented cooling modalities. Design: Randomized, counterbalanced, crossover design. Setting: Research laboratory. Participants: Fourteen recreationally active individuals (mean±SD: male, n=7, female, n=7; age=25±4y; height=171±9cm; body mass=70.8±8.3kg; percent body fat=21.2±7.6%). Intervention: Participants completed six bouts of treadmill exercise (55.2±12.2min) in a hot environment (38.5±1.5°C, 37.5±7.6%RH) until one of the following occurred: Tre reached 39.75°C, 80 minutes of exercise, or the participant requested to stop. Exercise sessions were followed by body cooling until Tre reached 38.00°C or for a maximum of 10 minutes. Cooling treatments (HC, cold-water immersion (CWI), forearm ice towels (IT), CWI+HC, IT+HC, and passive rest) were performed in a thermoneutral environment (22.4±1.6°C, 32.1±12.3%). Participants then returned to the
heat, equilibrated for 10 minutes, and conducted approximately 20 minutes of performance tasks. At 40 minutes post-cooling initiation, Tre was again obtained. Main outcome measures: Heart rate (HR) was measured before (PRE), after (POST) exercise while Tre was additionally measured immediately following performance tasks. Differences between cooling methods were determined using a repeated measures one-way ANOVA with pre-planned dependent t-tests. An a priori alpha level was set at 0.05. Results: POST HR (168±18 beats per minute), and POST Tre (39.17±0.46°C) were similar between groups (p>0.05). Upon initiation of cooling, Tre was also similar across groups (39.35±0.48°C, p>0.05). The cooling rate for passive rest (0.07±0.02°C·min-1) was lower than all other cooling conditions (p0.05) and resulted in lower Tre than all other conditions (p

▼ Quinoa (Chenopodium quinoa Willd.) sensitivity to high temperatures is an impediment to adoption in regions prone to
heat waves, despite quinoa being a highly resilient crop to a wide range of abiotic stresses. Although reductions in yield due to
heat are usually associated with pollen viability, the present study aimed to understand the effects of high temperature on the leaf and its capacity for carbon assimilation. Several trials were conducted with 10 quinoa genotypes classified as being either sensitive or tolerant to
heat stress on a previous screening of 112 lines. Plants were grown in the greenhouse at normal temperatures (i.e., control), and at the sixth growth stage were exposed to temperature treatments in growth chambers. The
heat treatment simulated
heat waves of four consecutive days with temperatures higher during the day and night (
Heat: 45/30 ˚C, and Control: 20/14 ˚C). Chlorophyll fluorescence (predawn and day), leaf gas exchange (day) and dark respiration (night) were measured during several experiments. In addition, leaf cell membrane stability was evaluated in the laboratory at temperatures of 47, 51 and 55 ˚C. Results show that most quinoa genotypes under the
heat treatment increased their photosynthetic rates and stomatal conductance, resulting in a lower intrinsic water use efficiency. These results were partly corroborated by changes in the maximum quantum yield of photosystem II (Fv/Fm). Dark respiration decreased under the
heat treatment in most genotypes. The cell membrane stability assays showed that temperatures of 51 ˚C or higher increased the percent injury to >70%, and a temperature of 47 ˚C may be a better screening temperature as injury was around 35%. These results suggest that
heat stress does not affect carbon assimilation capacity, but higher transpiration and lower intrinsic water use efficiency may lead to water deficits and exacerbate plant
stress responses, resulting in lower yields.

▼ Okra is an important summer vegetable crop and high temperature has been shown to lower its growth and yield. In this study, 119 okra genotypes were initially screened for their response to a short period of heat shock (45°C for 4h and 6h) in a controlled environment facility by assessing chlorophyll fluorescence (Fv/Fm and Fv’/Fm’), photosynthesis (A), stomatal conductance (gs) and electrolyte leakage (EL) in control and heat. Additionally, DNA of fresh green leaf of okra was isolated by a modified CTAB method with additional PVP and RNase and amplified by 8 polymorphic SSR markers to generate a dendrogram. This preliminary screening identified 8 polymorphic genotypes with less than 50% genetic similarity, reduced Fv’/Fm’ in the heat with varying responses in gs, A and EL. These 8 genotypes were studied for their response in a long-term heat stress environment in two adjacent plastic tunnel houses, with 10°C warmer average temperatures in the hot tunnel house. After 15 weeks, high temperature had no significant effect on Fv’/Fm’ and A, while gs and EL increased significantly and yield decreased due to significant reduction in pollen germination. The tunnel house experiment was repeated (with 4 genotypes) assessing physiological, biochemical and histological parameters at flowering and bud initiation stages and monitored every 2 weeks for a total of 6 weeks. Okra demonstrated a physiological acclimation response however yield decreased severely due to heat damage in reproductive tissue. In the heat, plants produced lower anther numbers and pollen germination. The shape and structure of male tissues was altered in the early stage of bud development which may have resulted from alteration in carbohydrate content in the leaves. The results of this study suggest that okra is more vulnerable in the early stages of growth and development.

▼ Thirty-two lactating Holstein cows averaging 169 ± 35 DIM were used to determine changes in energy use due to ration heat increment (HI) content under heat stress conditions. Dietary treatments were high HI ad libitum (HA), low HI ad libitum
(LA), and low HI at restricted caloric intake (LR). The LR cows were paired and restricted to HA daily NEL intake (Mcal/100 kg BW). The high HI diet was formulated with more forage and fibrous byproducts, whereas the low HI diet contained more starch and
fat from byproducts. Milk yield, milk composition, and energy-corrected milk yield were similar for treatments. Milk yield and energy-corrected milk yield per kg DMI were greater for LR compared with HA. Total energy efficiency was greater for LR than
for HA and LA treatment groups. Data indicates that HI is useful for reducing heat stress and improving energy efficiency in dairy cattle during heat stress.

▼ Roses (Rosa × hybrida) have been one of the most popular decorations for entertainment and ceremonies for the past 5,000 years, and have been used in the fragrance, medicinal, and food industry.
Heat stress is one of the most significant abiotic stresses which negatively affects rose performance and reduces the market value of roses. This project examined the effect of
heat on rose in diploid rose populations created by intercrossing
heat tolerant and sensitive diploid parents.
Changes in flower size were examined in a
heat shock (one hour at 44°C) experiment with potted plants and in field plots by comparing flower size in cool (spring and fall) versus warm (summer) seasons. As expected, the
heat treatment decreased flower diameter, petal number, and flower dry weight. Flower size traits had moderately low narrow sense heritability (0.24 - 0. 35, 0.12 - 0.33, and 0.34 - 0.37) and moderately high to high broad sense heritability (0.62 - 0.67, 0.74 - 0.91, and 0.76 - 0.81) for flower diameter, petal number, and flower dry weight respectively. The G×E variance for flower diameter and flower dry weight accounted for 37% and 27% of the variance in the field experiment indicating that the
heat stress had moderate differential genotypic effects as was indicated by the analysis of variance. However the genetic variance was several fold greater than the G×E variance indicating selection for flower size would be effective in any season but for the selection of a stable flower size (
heat tolerant) rose genotype, selection would be required in both the cool and warm seasons.
The number of flowers per primary and secondary inflorescence had very low narrow sense (0.01 and 0.06) and moderate broad sense (0.43 and 0.34) heritability. The G×E variance for the number of flowers per primary and secondary inflorescence accounted for 55.7% and 57.0% of the total variance in the field experiment indicating selection needs to be done for within each season. Only 26% of plants had tertiary inflorescences.

▼ This study was done to examine the effects of supplementing electrolytes to
heat stressed transitioning cows on dry matter intake (DMI), milk yield (MY), and blood metabolites. Overall, 104 Holstein and Jersey cows were utilized from August to September, 2012, and from August to November, 2013. Control (CON) cows were fed standard TMR and E+ cows received the same TMR plus 170 g of Bovine BlueLite. The DMI, MY and composition, rectal temperature, and respiration rate were monitored daily; while blood metabolites, body weight, condition score and frame size (withers height, hip height, and heart girth) were measured weekly. The DMI, MY and composition were not different among treatments. Health condition, body change, and blood chemistry were not affected by treatment. Electrolyte supplementation did not have any negative effects on performance of dry and lactating cows, but showed positive potential for alleviation of
heat stress in the present study.

▼ The objective of this study was to develop an in vivo model to assess thermoregulatory response of lactating dairy cows to
heat stress. Hyperthermia occurring for 10 to 12 hours after LH surge reduces quality of maturing oocyte, thereby reducing fertility. Between the months of February through May, cows were transported to a climate-controlled facility and maintained at a temperature-humidity index (THI) of 65.9 ± [plus or minus] 0.2 (thermoneutral) or exposed to increases in THI of 0.8 ± 0.1 units per hour (
heat stress) for 12 hours before rapidly cooling to thermoneutral conditions. Mixed model regressions with repeated measures were used to test respiration rates (RR) and rectal temperature (RT). Within 40 and 110 min of increasing THI, RR increased in a quadratic fashion (P < [less than] 0.001); RT increased by 0.04 ± 0.1° [degree] C (P < 0.001) per unit THI. Changes in RR lagged THI and preceded rises in RT by 30 min. Average THI 3-days prior to treatment influenced changes in RR (P = [equal] 0.050) and RT (P < 0.001). Increased RR was more noticeable in
heat-stressed cows when prior THI was in the 40s than low 60s. Rectal temperature of
heat-stressed cows was 0.8 ± 0.02°C lower when prior THI was in the 40s versus low 60s. Progesterone and LH levels before treatment were predictive of thermoregulatory response in
heat-stressed cows. Rapid cooling decreased RR by 0.6 ± 0.1 bpm (P < 0.001) and RT by 0.02 ± 0.002°C per min (P < 0.002). Speed and magnitude of thermoregulatory changes to an acute
heat stress and after sudden cooling emphasizes the importance of strategic cooling before ovulation. Efforts to do so when prior THI approaches levels expected to induce mild
stress are especially important. Respiration rate is a useful indicator of the degree of hyperthermia a lactating cow is experiencing during an acute
heat stress event.

▼ Wheat (Triticum aestivum L.) has been a major food crop for nearly 8000 years.
Breeders continue to face an ongoing battle to produce
stress tolerant cultivars that are
able to feed a rapidly increasing global population. The ability of varieties to perform
similarly in grain yield across various environments is an important trait that is critical to
successfully keep up with food demands with decreasingly available arable lands. The
work described in this dissertation focused on defining and understanding the genetic
interactions of epicuticular wax and high temperature and drought tolerance and its
association with yield stability, to better aid breeders in
stress tolerance selection. The
effect of high temperature on epicuticular wax, yield attributes and yield stability were
investigated in a recombinant inbred line population of 180 individuals from a Halberd x
Len cross by physiological and molecular techniques.
Epicuticular wax offers advantages in protecting the plant from both biotic and
abiotic stresses. Under HT conditions, EWL can reduce chlorophyll fluorescence by
reflecting excess irradiation and also reduce stomatal conductance, helping to regulate
the rate of transpiration. QTL for epicuticular wax with large effects were detected on
chromosomes 2A, 2B, 3A, 6B, and 7A. A large effect QTL for epicuticular wax was
detected in three field environments on chromosome 2B (QWax.tam-2B.1) with the
favorable alleles contributed by Halberd. QTL for yield stability and yield components
stability indices with large effects were detected on chromosomes 1A, 1B, 2A, 2B, 3B,
6B, and 7A. A large effect QTL for yield stability was detected by five stability statistics over diverse field environments on chromosome 1B (Qyieldss.tam-1B) with Halberd
contributing the favorable alleles. High EWL may promote stable yields but its
sensitivity to environmental conditions makes it challenging to definitively point to it as
a source of improved stability. Although there were mixed relationships with yield
performance and environments, the stability statistics QTL provide strong evidence that
genetic variation may be heritable and could have implications for breeding programs
targeting a set of environments rather than a single environment.

▼ Fission yeast Srk1 kinase is essential for cellular responses to extracellular stimuli. It is activated downstream of the MAPK Spc1 and participates in controlling mitotic entry by directly phosphorylating and inhibiting Cdc25 phosphatase during the normal cell cycle and also in response to osmotic stress. Following phosphorylation, Cdc25 is exported out of the nucleus. Heat stress caused by a temperature shift from 25°C to 36°C, which is within the normal temperature tolerance of fission yeast, temporarily inhibits nuclear division in wildtype cells. The same response is seen in cells deleted for the Pyp1 and Pyp2 phosphatases which normally serve to down regulate the Spc1 stress response. I have shown that the transient block in nuclear division caused by temperature shifts within the physiological range does not occur in srk1- cells but instead there is a stimulation of mitosis and cell division in response to the heat stress. This pattern of mitotic stimulation is phenocopied in cdc25-9a cells where nine putative Srk1 phosphorylation sites on Cdc25 are changed to alanine. Cells lacking srk1, however, display the same cell cycle progression pattern as the wildtype cells in response to osmotic stress. This experiment clearly distinguishes separate pathways for these two stress responses. Also, Cdc25 is found to be phosphorylated after a mild heat stress and seems to be exported out of the nucleus. These data indicate that Srk1 kinase plays the central role in regulating mitotic entry in response to mild heat stress by negatively regulating the Cdc25 tyrosine phosphatase. Thus my work highlights the role of Srk1 kinase in cell cycle regulation and is consistent with the Spc1 MAPK cascade linking the G2/M transition to extracellular stress. This response to mild heat stress is important because temperature sensitive mutants are frequently used in fission yeast research and this work shows that a temperature shift from 25°C to 36°C, which is within the physiological growth range, can trigger a stress response.

▼ This thesis is an investigation of the effects of foliar boron (B) application on alleviating
heat stress in spring canola (Brassica napus L.). Canola is a cool season crop and as such it is sensitive to high temperature
stress during flowering.
Heat stress during this period results in yield loss due to pod abortions. Field and controlled environment experiments were conducted to investigate the benefits of foliar B applications and to determine if B application could alleviate the effects of
heat stress. Field results indicated that benefits of B application are inconsistent, but may be more likely when the growing season is very warm and dry. In controlled environment experiments, plants were exposed to three temperature regimes at three development stages for three durations. Based on this a
heat stress protocol that produced a 25% reduction in viable pod numbers was selected to be used for testing B effects. Using this protocol, B application was shown to significantly reduce pod abortions when compared with the treatments without B. B application reduced pod abortion in the presence of
heat stress.

▼ This dissertation is focused on the assessment and prevention of
heat-related illnesses in
mineworkers due to excessive exposure to
heat and humidity in hot environments.
Heat
stress is a serious environmental and occupational hazard. The damaging effects of
heat
stress can lead to major injuries such
heat stroke,
heat exhaustion, or even death. Recent
trends indicate no progress towards decreasing the
heat-related accidents in the mining
industry as reported by the U.S. Mine Safety and Health Administration, despite
unquestionable advances in the area of mine safety in the last twenty years. Adherence to
standardized
heat indices that are appropriate in mining work-site environments is
decidedly beneficial.
The purpose of the study was to: i) review of the current state of knowledge about
heat
stress and strain from published and specialized literature; ii) validate the Predicted
Heat
Strain (PHS) [ISO 7933 (2004)] model, one of the most scientifically robust index,
through a comparison of the predicted core temperatures by the PHS model with a direct
physiological measurement obtained from an ingestible telemetry pill (VitalSense
capsule), and iii) improve the performance and accuracy of the PHS model by developing
a new expression that relates core body temperature as a function of stored
heat and skin
temperature. Primary sources of data for the current study, including environmental and
real-time physiological data, were collected from ten subjects performing typical mining
activities at two underground mines located in Arizona.

▼ Heat related illness has been recorded in dogs undertaking strenuous exercise in high temperatures. In South Australia, summertime daily maximum temperatures may reach 50°C. This study aimed to determine if a safe maximum ambient temperature for racing in greyhounds can be established and if particular environmental or phenotypic factors increase the risk of greyhounds developing hyperthermia. A preliminary study compared four temperature recording devices to determine their suitability for use in a racing environment. Digital rectal thermometry was the most reliable and convenient method of recording greyhounds’ body temperature. An observational study was then undertaken at racetracks in South Australia, during which, environmental temperature and relative humidity were recorded and greyhounds’ body temperatures measured on arrival, pre- and post-race. A mean increase of 2.1 ± 0.4 °C in greyhounds’ (n=239) post-race rectal temperature was recorded. No association was found between environmental temperatures and greyhounds’ temperatures on arrival or pre-race. However, post-racing there was a small but significant relationship between shade temperature and both rectal temperature (r² = 0.023, P = 0.027) and the increase in rectal temperature (r² = 0.033, P = 0.007). No association between environmental relative humidity and body temperature was detected. The influence of sex, bodyweight and coat colour on body temperature increases were investigated. There was a small but significant relationship (r² = 0.04, P = 0.009) between bodyweight and post-exercise rectal temperature. Greyhounds of dark colours developed higher temperatures than light coloured greyhounds (P <0.05). Animal housing at racetracks was examined and temperature and relative humidity levels in enclosed environments were recorded using data loggers and ibuttons. A significant relationship was found between kennel house temperatures and body temperature changes of greyhounds during racing (r² = 0.03, P = 0.009). Temperature and relative humidity levels in dog transport vehicles were monitored with ibuttons when vehicles were stationary and moving in both laden and un-laden states. The effects of an air conditioning system on conditions within a vehicle were measured and responses of dog body temperatures to transport were assessed. In ambient temperatures <33°C the air conditioning system maintained internal trailer temperature below 26°C. Between ambient temperatures 33-37°C, although the internal temperature in the air conditioned trailer rose above 26°C, dogs were able to maintain normal body temperature. Following journeys of approximately 50 minutes in a trailer without air conditioning, mean dog rectal temperature increased by 0.5°C ± 0.2. Results of these studies have identified a number of factors which may increase the risk of greyhounds developing a potentially hazardous level of hyperthermia after exercise. Following racing in external environmental temperatures ≥38°C, 39% of greyhounds developed rectal temperatures ≥ 41.5°C. Large, dark…

▼ The current thesis examined local and whole-body heat loss responses during heat stress at rest, exercise and/or pharmacological stimuli as a function of increasing age. The first study examined the effects of age on whole-body heat loss and heat storage during passive exposure to conditions representative of the upper temperature extremes in Canada. The results demonstrate that the cumulative change in body heat content after 2 h of rest was significantly greater in older adults in a hot-dry (older: 212±25; young: 131±27 kJ, P=0.018) and hot-humid (older: 426±37; young: 317±45 kJ, P=0.037) condition. The second study evaluated the maximal capacity of whole-body evaporative heat loss as a function of age and aerobic fitness. The findings demonstrate that whole-body evaporative heat loss was significantly lower in middle-aged untrained (Ex2: 426±34; Ex3:497±17 W) and older (Ex2: 424±38; Ex3: 485±44 W) compared to young (Ex2: 472±42; Ex3: 558±51 W) and middle-aged trained (Ex2: 474±21; Ex3: 552±23 W) males at the end of the last two exercise bouts (P<0.05). The third study assessed the maximal capacity of whole-body evaporative heat loss in females and found that whole-body evaporative heat loss was significantly lower (P=0.002) in the older (Ex2: 343±39 W; Ex3: 389±29 W) compared to the young (Ex2: 383±34 W; Ex3: 437±36 W) females at the end of the second and third exercise-induced heat loads of 325 and 400 W, while no differences were observed during recovery (P=0.693). The fourth study examined nitric oxide-dependent sweating during exercise/rest cycles in young and older adults. We showed that nitric oxide-dependent sweating during short bouts of exercise in the heat is observed in young males, but not in older adults. The fifth study examined: 1) the extent to which peripheral factors (i.e., sweat gland and skin vasodilatory function) contribute to the postexercise suppression of heat loss; and 2) whether age-related differences exist in the mechanisms modulating postexercise heat loss. The findings demonstrate that there were no differences in sweat rate between the no exercise resting condition and a postexercise condition at either an acetylcholine (ACh) or methacholine (MCh) site for the young (ACh: P=0.992 and MCh: P=0.710) or older (ACh: P=0.775 and MCh: P=0.738) adults. However, older adults had a lower sweating response for both the no exercise resting condition (ACh: P=0.049 and MCh: P=0.006) and postexercise condition (ACh: P=0.050 and MCh: P=0.029) compared to their younger counterparts. Taken together, the current thesis shows true age-related impairments in the ability to dissipate heat exist during both a passive and exercise-induced heat stress over a certain heat load threshold. Specifically, older adults have an impaired ability to dissipate heat compared to young adults during rest in hot-dry and hot-humid conditions. Additionally, middle-aged untrained and older adults have a reduced capacity to dissipate heat at an exercise-induced heat load of ≥400 W for males and ≥325 W for females, which…

▼ Environmental factors such as high humidity and temperature can cause
heat stress.
Heat stress during the dry period reduces milk yield in the next lactation. Previous data have shown that feeding OmniGen-AF before and during periods of
heat stress increases dry matter intake (DMI), reduces respiration rate (RR) and rectal temperature (RT), and it may improve immune status of
heat stressed dairy cattle. The objective of the present experiment was to evaluate the effect of
heat stress (HT vs CL, during the dry period) and dietary treatment (Control vs. OG) during and after the exposure to
heat stress on dairy cow performance. At least 60 days before dry-off, cows were randomly assigned to OG or Control treatments based on the 305-d mature equivalent milk yield. Cows were supplemented with 56 g/d of OmniGen-AF or equal amount of AB20 as control during the last 60 days of lactation, dry-period and up to 60 days in milk. Cows were assigned to four treatments in a completely randomized design with a 2x2 factorial arrangement of treatments. Cows were dried off 45 d before expected calving and, within OG and Control they were randomly assigned to receive only shade with no evaporative cooling (HT, n = 36), shade with evaporative cooling (fans and soakers, n = 30),
heat stress with placebo (HT, n = 17),
heat stress with OG (HTOG, n=19), cooling with placebo (CL, n = 16) and cooling with OG (CLOG, n = 14). The present study demonstrated that HT vs. CL increases RR and RT, and OG supplementation improves thermoregulation of cows exposed to HT by reduction in RR and a tendency to reduce RT. Cows exposed to HT vs. CL reduces DMI during the dry period. The exposure to CL and OG treatment improves milk yield in the next lactation. Also, OG supplementation improves L-selectin mRNA gene expression during late and early lactation of Holstein cows and tended to increase neutrophil volume during the dry period. However, CL and OG improve cow performance and OG supplementation may be a strategy to improve the immune status of cows. ( en )

▼ Post-flowering
heat stress is one of the major
environmental constraints for wheat (Triticum aestivum L.)
production in the state of Kansas, where wheat is the most widely
grown grain crop. Studies have shown that the optimal temperature
for wheat grain development is approximately 21°C. During the grain
filling stage for wheat in Kansas, it is fairly common for
temperatures to reach more than 30°C and above. These scenarios
have resulted in lower productivity and yield in Kansas compared to
other regions of the United States. Therefore the objectives of
this research project included: phenotyping seven Kansas varieties
for post-flowering
heat tolerance in a controlled environment
growth chamber study as well as in two field experiments,
estimation of spike and flag leaf senescence in wheat exposed to
post-flowering
heat stress, and identifying potential genetic
donors for
heat tolerance from winter wheat breeding lines and Near
Isogenic Lines developed from Kansas State University’s Wheat
Breeding Program. To impose
heat stress in the controlled growth
chambers, plants grown at 25°C were transferred to high day
temperature (35°C) chambers ten days after the first sign of
anthesis. Under field conditions, custom built “
heat tents” were
placed over the wheat plots ten days after first flowering and
remained until maturity. Plants grown under
heat stress exhibited
early senescence, indicating a shorter grain filling period
compared to the controls. Early-maturing varieties recorded greater
percent reductions in grain yield under
heat stress. Post-flowering
heat stress induced significant reductions in thousand kernel
weight, grain number, harvest index, and grain yield. Spike and
flag leaves effective quantum yield of PSII was reduced more
drastically under growth chamber
stress exposure compared to field
grown plants. Significant genetic variation in the spike and flag
leaf senescence initiation and the differential rate of senescence
among the seven tested varieties suggested the potential for
considering this trait in breeding programs. Compared to the
commercially relevant varieties, breeding lines varied less under
heat stress with a few lines recording a greater degree of
heat
resilience and experienced little to no drop off in
heat stress
conditions compared to control. The reduced performance under
heat
stress for the seven varieties highlights the genuine need to
explore wider genetic diversity, including wild wheat, to infuse
greater resilience into ongoing wheat breeding programs. However,
the results observed in the breeding lines indicate that
introducing larger genetic diversity may aid in developing greater
heat stress resilient wheat varieties for current and future
changing climate.

▼ Heat stress (HS) causes significant losses to the U.S. swine industry in several production and health areas including efficient lean tissue accretion. Perturbations in skeletal muscle metabolism may participate in this defect. The study objectives were to examine the cellular bioenergetic profile in skeletal muscle of piglets subjected to thermal
stress in utero and/or during postnatal life. To accomplish this, 96 offspring from 14 sows were prenatally exposed to 1 of 4 environmental treatments involving thermal neutral (TN, 25°C) or HS conditions (cyclical 28-34°C). Sows exposed to TN or HS throughout gestation are denoted TNTN and HSHS, respectively whereas sows
heat-stressed for the first or second half of gestation are denoted HSTN and TNHS, respectively. At 14 weeks of age, offspring were exposed to one of two postnatal thermal environments, constant TN (21°C) or HS (35°C) for 24 hrs (acute study) or 5 weeks (chronic study). Pigs were sacrificed after treatment and longissimus dorsi skeletal muscle samples collected for molecular analyses. Differences (p<0.05) were observed in protein abundance of p-4eBP1 and total Rs6 and gene expression of Cox5B, CytB, EEF2, HK2, MURF, ND1, PGC-1α, SDHA, and TFAM during the acute
heat stress study. Differences (p<0.05) were observed in protein abundance of 4eBP1, total Akt, and p-Rs6 and gene expression of CytB, MURF, and PGC-1α during the chronic
heat stress study. These data indicate that acute postnatal HS alters skeletal muscle metabolism, which may favor a reduction in mitochondrial respiration and protein synthesis potentially via the mTOR pathway.

▼ Over the past fifty years the University of Montana, in conjunction with the United States Forest Service, has been investigating the job demands of wildland firefighters. This document is a combination of three research projects with a connection of health and safety of wildland firefighters.
Smokejumpers are unique because they parachute into remote fires and are used primarily as initial attack wildland firefighters. Studies have shown that initial attack is the most energy intensive part of wildland firefighting. The first study identifies maximal and sustainable aerobic fitness possessed by US Smokejumpers. The maximal aerobic characteristic of US smokejumpers is well above average aerobic fitness compared to the general population, and sustainable aerobic fitness is similar to the fitness required for fire line digging during initial attack on wildland fires. There is also no difference between gender and age groups.
The second study identifies the relationship between smokejumper core critical tasks (fireline digging, packing loads over 85 lbs, and repetitive lifting/carrying) and the current physical training (PT) test. The smokejumper PT test uses push-ups, pull-ups, sit-ups and a 1.5 mile run to determine if individuals have the minimal fitness required for successful job performance. This study found a relationship between push-ups, pull-ups and the 1.5 mile run to smokejumper core critical tasks, but there was no relationship with sit-ups.
While physical fitness helps to mitigate certain risks associated with fire suppression, it alone is not enough, so personal protective equipment (PPE) is also used maximize safety. The majority of specifications used in construction of this equipment considers only the external environment and does not consider the individual as part of the environment. The third study evaluated the thermal stress on the human body with three typical configurations of personal protective equipment. The use of increased layers of PPE was found to increase the thermal stress identified by body temperature and physiological strain index. The use of two layers of PPE compared to one decreased potential work time by half before a critical core temperature was reached.

▼ Abiotic stresses including high temperatures and moisture deficit are detrimental to bread wheat production. Under abiotic stresses, characteristics such as yield, growth rate, gene expression and quality are affected and responses might involve interaction of many genes. Most studies on the impact of abiotic stresses such as high temperatures and moisture deficit have concentrated on effects on yield and agronomic traits with less work being done on grain quality. This project focussed on the end-use quality of wheat grain produced under a range of field production conditions including high temperatures and water shortages, using two mapping populations, Gladius/Drysdale and RAC875/Kukri. Gladius, Drysdale and two pairs of backcross derivatives having Wyalkatchem and RAC1262A as recurrent parents were also studied under normal and
heat stress conditions in a glasshouse experiment. Of the backcross derivatives, one line of each pair has a Gpc-B1 (high grain protein content) gene introgression and the other does not. Field trials were conducted in Australia and Mexico and the glasshouse experiment was conducted in Australia. For the glasshouse experiment, Gladius showed more
heat tolerance with no significant decrease in grain weight compared to Drysdale. The backcross derivatives with the introgression segment had higher grain protein content, percentage unextractable polymeric protein and accelerated senescence than ones without the segment. Grain weight and senescence were severely affected by
heat stress. Quality analysis of field grown material involved sequential assessment of grain, flour, dough and baked product characteristics.
Stress conditions increased protein content, decreased yield, grain thickness, width and increased dough development time compared to the control. The exposure to
heat stress resulted in an increase in loaf volume compared to the control experiment. Genetic linkage maps were constructed for the Gladius/Drysdale population and used for quantitative trait loci (QTL) analysis. Quantitative trait loci analysis detected several genomic regions associated with quality traits under a range of conditions including drought and
heat stress in both populations. Some of the traits were associated with known phenology and quality genes, some QTLs detected have been reported in other studies but some QTLs were novel and had not been detected elsewhere. The novel QTLs detected under conditions involving
heat and drought
stress present opportunities for selection of lines that are able to maintain quality under these adverse conditions.

▼ Heat stress (HS) is a multi-billion dollar global problem as it impairs animal performance during the summer. Heat stress has been implicated in promoting oxidative stress either through excessive production of reactive oxygen species (ROS) or decreased antioxidant defence. Excessive ROS production overwhelms the antioxidant defence, and this leads to oxidative damage of biological molecules including proteins, lipids and DNA, which in turn disrupts normal metabolism and physiology. Therefore, a robust antioxidant network capable of preventing oxidative damage of biological molecules holds promise for improving the health and performance of animals during heat stress. This thesis investigated the impacts of heat stress on the oxidative stress biomarkers, elucidated potential role and optimized the dose of vitamin E and selenium required to ameliorate heat stress in sheep.
The first study investigated the impact of HS and dietary antioxidant supplementation on the oxidative and physiological status of sheep. This study showed that heat stress negatively affects the oxidative status of sheep along with the physiological responses; however some of these affects can be ameliorated through dietary vitamin E (Vit E) and selenium(Se) supplementation at supranutritional concentrations. To understand the molecular mechanisms involved in heat stress ameliorative action of Vit E and Se, mRNA expression of heat shock proteins (HSP) and pro-inflammatory genes were investigated. High dietary antioxidants proved to modulate skeletal muscle expression of HSP, pro-inflammatory cytokine and NFĸB transcription factor, which may protect against HS in sheep.
The potential role of high dietary Vit E or Se in amelioration of HS in sheep, and changes in acid base balance and respiratory oxidative stress biomarkers along with systemic biomarkers, were investigated in the second study. This study suggested that the hydrogen peroxide concentration in exhaled breath condensate (EBC) can be utilized as a novel biomarker to demonstrate respiratory oxidative stress induced by HS in sheep. The study also highlighted the potential of Se to reduce respiratory oxidative stress. While Vit E improved the physiological responses of heat stressed sheep; combined supplementation of Vit E and Se was required to prevent the acid base imbalance in heat stressed sheep.
Finally, optimization of dietary levels of Vit E and Se to improve the performance and oxidative status of lambs finished during hot conditions was undertaken. This study suggested that supranutritional levels of dietary Vit E and Se increased average daily feed intake and the average daily gain in lambs during finishing and maintained the oxidative balance during exposure to HS.
Thus it is suggested that heat stress leads to oxidative stress in sheep and supranutritional supplementation of dietary Vit E and Se can be used as a nutritional strategy to ameliorate negative effects of HS in sheep. Further research is required to elucidate the effects of dietary Vit E and Se on…

▼ It has been reported that microalgae can be found in the air, but aerial microalgae have not been investigated seriously. Microalgae lives in watery and moist environments. When dispersed in the air, these cells have to tolerate drought
stress, UV radiation, and either high or low temperature in order to survive. For the cells that can survive these environmental stresses, they have a chance to quickly expand their habitats by using wind as a means to spread. To investigate what microalgal species can survive these stresses and what mechanisms they use, four new species of aerial microalgae were isolated on Dongsha Island in South China Sea in the seasonal northeast wind. Based on 18S rDNA and ITS sequences and morphological analyses, the four new species were named Scenedesmus sp. DSA1, Coelastrella sp. DSA2, Coelastrella sp. DSA3 and Desmodesmus sp. DSA6, which are members in the family Scenedesmaceae. Their tolerance to environmental stresses were assessed, and the potential mechanisms were studied. The cell wall thickness of the four species and two controls positively correlates to their UV tolerance. The tolerance to drought and low temperature of DSA1, DSA2 and DSA3 is extremely high. Freeze-drying (lyophilization) could not kill these cells, and this phenomenon could not be explained by water content in the dried cells or their antioxidation capacities in these cells. Thermotolerance of DSA1, DSA2 and DSA6 is among the highest in the literature. These cells in liquid culture could survive at 50 â. The carotenoid levels in the stressed DSA2 and DSA3 cells were higher than in the DSA1 cells, followed by that in the DSA6 cells. These carotenoids contained astaxanthin, adonirubin, lutein,canthaxanthin, and ï¢-carotene analyzed by using HPLC.

▼ Soil salinity and
heat stress are two major abiotic stresses affecting plant growth and yield. Transcription factors (TFs) are key regulators in
stress responses. They link
stress sensing with many tolerance mechanisms by translating
stress signals into changes in gene expression that ultimately contribute to
stress tolerance. The NAC (NAM, ATAF and CUC) TF family have been found to be involved in responses to biotic and abiotic stresses. In this PhD project, the role of NAC TFs in response to
heat and salt
stress was studied in the model system Arabidopsis thaliana (Arabidopsis), and in two agriculturally relevant species, Solanum lycopersicum (tomato) and Chenopodium quinoa (quinoa).
Plants have the ability to acquire thermotolerance if they are pre-exposed to a mild, non-lethal high temperature. The maintenance of acquired thermotolerance for several days is known as thermomemory. Here we investigated the role of NAC TFs in thermotolerance. The expression profiles of 104 Arabidopsis NAC TFs were measured and compared between primed and unprimed plants. Some NACs with a distinctive expression pattern in response to thermopriming were selected for further phenotypic analysis. Knock-out (KO) mutants of the ATAF1 gene showed an enhanced
thermomemory phenotype compared with wild type plants (WT) and from this work, the functions of the ATAF1 gene were studied further. RNAseq co-expression analyses of ATAF1 overexpressor and ataf1 KO plants found that ANAC055 expression was co-regulated with that of ATAF1.
JUBGBRUNNEN1 (JUB1) is another NAC TF involved in responses to
heat, drought and salinity. In this study, the role of AtJUB1 overexpression in salinity was investigated in tomato plants. AtJUB1 overexpression resulted in higher proline levels and improved maintenance of water content and biomass in AtJUB1-overexpressing plants grown hydroponically under salinity compared with WT plants.
Quinoa has recently gained much attention because of its high nutritional value and high tolerance to several stresses including drought and salinity. NAC TFs are hypothesized to play a major role in quinoa’s tolerance to abiotic stresses. In this study, the NAC TFs family were identified and investigated in the genome of quinoa. 107 NAC TF genes were identified and their transcriptional responses to different stresses including salt, drought and
heat were investigated.

▼ Athletic trainers must consider environmental conditions when making decisions concerning football practices. Those working in southern settings are faced with stressful environmental conditions often associated with the late summer and
early fall. Strategies to minimize heat stress include proper acclimatization, hydration, conditioning, heat illness recognition, and weather monitoring. The purpose of this study was to evaluate the rate of exertional heat illness (EHI) in athletes
during a three month period (August-October) at five southeastern universities. The Heat Stroke Checker (KEM Kyoto Electronics Manufacturing Ltd; Japan) was used to measure environmental conditions three times a day at each location. The American College
of Sports Medicine (ACSM) and Department of Defense (DOD) Wet Bulb Globe Temperature (WBGT) Heat Stress Index Charts were used to identify the levels of heat illness risk. Heat cramps, heat syncope, heat exhaustion, heat stroke, and hyponatremia were
evaluated based on the NATA Exertional Heat Illness position statement. A reportable injury was any athlete who incurred a heat related illness evaluated by the medical staff. A total of 139 heat-illnesses were reported with an EHI rate of 4.19/1000
athlete-exposures (AE) during the three-month period. No cases of heat stroke or hyponatremia were reported. Evaluating each month individually, the greatest number of EHI’s occurred during August (88%) with an EHI rate of 8.95/1000 AE. During August,
the EHI rate was 6.31/1000 AE for heat cramps, 2.06/1000 AE for heat exhaustion and 0.58/1000 AE for heat syncope. Pearson correlations between the ACSM and DOD Heat Stress Index Charts and specific heat illnesses were not statistically significant
relationships (p>.05). In our study we found a higher heat exhaustion injury rate compared to the NCAA surveillance data possibly due to differences in EHI definitions and reporting mechanisms. The incidence of heat illness in the months of September
and October decreased dramatically, suggesting football athletes are at greatest risk of heat illness during August. Our data suggests that during the late summer, previously reported guidelines may overstate the risk of heat illness in highly trained
football athletes practicing with the southeastern United States. The development of regionally specific heat index guidelines is recommended.

▼ This thesis examined the extent to which type 2 diabetes (T2D) affects the body’s ability to dissipate heat during passive and exercise heat stress. Three experimental studies were performed to examine 1) whole-body heat loss and heat storage in habitually active older adults with and without T2D during a 3-hour resting exposure to extreme heat, 2) local and whole-body heat loss responses between older habitually active males with and without T2D during exercise at increasing fixed exercise intensities (and therefore level of heat stress) in the heat, and 3) whether short-term heat acclimation could reduce T2D-mediated impairments in whole-body heat dissipation. The first study showed that older adults with T2D did not have impaired whole-body heat loss (T2D: 75±25 W; Control: 71±22 W, P=0.90) and heat storage (T2D: 344±111 kJ; Control 346±139 W, P=0.98) and thus experienced similar thermal strain compared to their healthy counterparts during a 3-hour passive extreme heat exposure. The second study showed that T2D impaired whole-body evaporative heat loss in a heat load-dependent manner, such that a lower response was observed during moderate (211±26 vs. 229±23 W.m-2, P=0.04) and high (234±36 vs. 261±30 W.m-2, P=0.03), but not low (172±23 vs. 184±17 W.m-2, P=0.12), intensity exercise in hot, dry conditions. This led to the T2D group storing progressively more heat with each successive exercise bout relative to their healthy counterparts, leading to a 27% greater change in body heat storage for T2D (651±204 kJ) compared to Control (476±157 kJ, P=0.01) over the three exercise bouts. In the third study, short-term heat acclimation increased evaporative heat loss by as much as 13±5% for T2D, whereas it was only increased by as much as 6±6% for Control (P=0.01). As a result, evaporative heat loss was similar between groups during moderate (239±25 vs. 254±16 W.m-2, P=0.15) and high (T2D: 279±27; Control: 294±19 W.m-2, P=0.21) intensity exercise following heat acclimation, leading to similar body heat storage between groups (T2D: 380±172 kJ; Control: 297±116 kJ, P=0.14). Altogether, the results of this thesis showed that habitually active older adults with well-controlled T2D do not display an impaired capacity to dissipate heat during passive heat exposure, albeit impairments in heat dissipation became evident at exercise-induced heat loads ≥200 W.m-2 when performed in dry heat, with the magnitude of that impairment becoming greater with increases in heat load. These impairments in evaporative heat loss capacity can be mitigated by short-term heat acclimation and possibly reduce the risk of heat-related illness during exercise and/or work in the heat.

▼ Purpose: The purpose of this study was to determine heat acclimatization across a 4-month fire season in the western United States. Methods: Wildland firefighters (WLFF) (n =12) and non-WLFFs (n =14) completed a 60-min heat stress trial (treadmill walking at 50% peak VO2) in a climate controlled chamber (43.3°C, 33% RH) prior to and following the fire season (May through September). Peak VO2, body composition, core (Tc) and skin (Tsk) temperatures, heart rate (HR), physiological strain index (PSI), plasma volume change, sweat rate and perceived exertion (RPE) were measured during the heat stress trials. Results: Average peak VO2 was similar between groups (54.1 ± 1.3 and 57.3 ± 2.0 ml.kg-1.min-1, WLFFs and non-WLFFs respectively, p>0.05) and did not change over the season. During the heat trial, WLFFs demonstrated a season-by-time reduction in Tc at 45 and 60-min (38.3 ± 0.3°C vs. 38.1 ± 0.3°C and 38.5 ± 0.3°C vs. 38.2 ± 0.4°C at 45 and 60-min, pre- vs. post- season, respectively, p<0.05), and PSI for the last 30-min (5.6 ± 0.9 vs. 4.9 ± 1.0; 6.5 ± 0.9 vs. 5.8 ± 1.2; 7.1 ± 1.1 vs. 6.3 ± 1.3 at 30, 45, and 60- min, pre- vs. post- season, respectively, p<0.05), as well as a decrease in RPE (11.2 ± 2.1 vs. 10.2 ± 1.6, pre- vs. post- season, main effect for season, p<0.05). In contrast, there was no difference in Tc, PSI or RPE for non-WLFFs. Conclusion: WLFFs demonstrated less physiological strain with significant decreases in Tc and PSI despite no change in aerobic fitness (peak VO2), suggesting that heat acclimatization adaptations are accrued due to long-term environmental/occupational heat exposure.

▼ A set of 37 strains including 13 serotypes of <I>Listeria monocytogenes</i> (<i>Lm</i>) were
analyzed for
heat tolerance at 60°C for 10 min and further categorized into three groups;
low (strains with <2 log survival), medium (2-4 log survival), and high (4-6 log survival)
heat tolerant. When <I>Lm</I> strains representing each group were subjected to sub-lethal heatstress
at 48°C prior to 60°C, the survivals of all strains were increased by at least 5 log
CFU/ml when compared to controls. Sub-lethal
heat-
stress at 48°C for 30-60 min
increased the
heat-
stress resistance of <I>Lm</I> strains by doubling D
60°C values from 1.9-4.3 to
5.0-10.4 min. When <I>Lm</I> cells were cooled after sublethal
heat-
stress at 48°C prior to 60°C
treatment, such acquired
heat-
stress adaptation was unstable at 22°C but was found to be
highly stable for up to 24 h at 4°C. These results will have potential implications in food
safety risk analysis for <I>Lm</I>.

▼ Scratch test and scanning electrochemical microscopy
(SECM) were applied to study the effects of thiosulfate on stress
corrosion cracking (SCC) of Alloy 800 in simulated crevice
solutions. The results showed that thiosulfate cathodically shifted
the pitting potential of Alloy 800 significantly and the pitting
morphology on the electrode surface was also different from that
formed in the absence of thiosulfate. The synergistic effect
between thiosulfate and stress was also observed, which was mainly
promoting enhanced anodic dissolution at active sites. In the
lead-induced stress corrosion crackings (PbSCC) work, the crack
propagation rate (CPR) of Alloy 800 double cantilever specimen were
estimated in neutral crevice chemistries solutions at 300 degree
Celsius. The PbSCCof alloy 800 at high temperature were
investigated by comparing the CPR rate of Pb-contaminated and
Pb-free conditions. A repetitive behavior of crack advance was
observed from the measurement. This observation is consistent with
the film rupture model.

▼ Heat and drought
stress are two of the most
significant abiotic stresses limiting wheat production in the Great
Plains and worldwide. Introgression of novel tolerance genes from
wild relatives is a strategy which presents promise. This study
examined both
heat and drought tolerance from the tetraploid
species Aegilops geniculata (U[superscript g]U[superscript
g]M[superscript g]M[superscript g]). Additional screening for
heat
tolerance was conducted with the US genome species Aegilops
peregrina (Hack) and Aegilops kotschyi (Boiss). A comprehensive
screening system for drought tolerance was also constructed to
evaluate wheat and its wild relatives.
Previous reports suggested
that Ae. geniculata accession TA2899 was moderately tolerant to
heat stress. It had also previously been used to develop a full set
of wheat-Ae. geniculata chromosome addition lines in a Chinese
Spring background. To identify the chromosome(s) carrying the
heat
tolerance, all addition lines, as well as wheat check genotypes,
were screened for post-anthesis
heat tolerance in two growth
chamber experiments. No chromosome addition lines were
significantly different (p<0.05) from Chinese Spring, and none
were found to have superior performance to the positive check
cultivars.
Forty-five accessions of Ae. peregrina and its close
relative, Ae. kotschyi were screened in a post-anthesis
heat
experiment. A follow-up experiment compared the genotypes in a
split-plot temperature treatment with
heat and optimal growth
chambers. Many accessions were similar to the control genotypes for
grain fill duration, and some exceeded the wheat controls for
relative chlorophyll index values on Day 12 and Day 16. TA1889 and
TA1904, both Ae. peregrina accessions originating from Israel, had
a higher grain fill duration across experiments than the best wheat
control, and warrant further investigation.
Previous reports
suggested drought tolerance in Ae. geniculata. After preliminary
screenings, six genotypes were selected for advanced screening and
compared with three wheat cultivars. The advanced greenhouse
screening system was conducted in 152cm tall PVC growth tubes. The
experiment measured multiple plant responses, and had a datalogging
system automatically collecting water content and matric potential
of the growth media. Multiple accessions warranted further
investigation, and showed potentially different modes of drought
tolerance, with varying levels of stomatal resistance, biomass, and
osmotic adjustment.

▼ Cotton (Gossypium hirsutum L.) crops usually experience some type of environmental
stress during the season. Soil moisture deficits along with high temperatures pose the biggest constraints for crop productivity. Although usually hard to distinguish between drought and high temperature
stress effects, it is important to develop means to help mitigate the negative impacts of such stresses on crop productivity. The 1-methylcyclopropene (1-MCP) is an ethylene antagonist that acts by binding to ethylene receptors, thus delaying and/or diminishing its effects on plants. Recently 1-MCP became the focus of several studies due to its potential to mitigate negative impacts of abiotic stresses. The main objective of this research was to assess the impact of 1-MCP on field grown cotton. The secondary objective was to investigate the association of canopy temperature (CT), canopy temperature depression (CTD),
stress degree day (SDD), thermal
stress index (TSI), and crop water
stress index (CWSI) with crop yield. Field studies were conducted at the Texas A&M University Field Laboratory in Burleson County, TX from 2012 to 2014. Plots were arranged in a randomized complete block design and replicated four times. Treatments consisted of 1-MCP application (25 g a.i. ha
-1) triggered by canopy temperature (28 °C) and forecasted ambient temperatures (35 and 27.8 °C). For the secondary objective treatments were two irrigation levels, namely, dryland and irrigated.
Results indicated that 1-MCP had little to no effect on the physiology and morphology of cotton at different stages of crop development. Daily plant canopy temperature, net photosynthesis, transpiration, and photosystem II quantum yield were affected by 1-MCP treatment when plants were irrigated, but not under dryland conditions. Effects of 1-MCP applications during different seasons were inconsistent. Ultimately, 1-MCP treatment effects were not enough to increase final seedcotton yield under the conditions tested. Negative relationships between yield and CT (r
2 = 0.66), yield and TSI (r
2 = 0.70), and yield and CWSI (r
2 = 0.58) were found. CTD and SDD showed great distinction between the humid (2012 and 2014) and dry (2013) years, and to a lesser extent, this was also apparent for CWSI. Evidence suggests that CTD, SDD, and CWSI models should be interpreted with caution, particularly in locations where great inter-annual weather variability occurs.

▼ Appropriate microclimates are essential for the development of embryos in avian eggs. Physical demands of incubating adults would also be affected by microclimate. The breeding areas of the Roseate Tern (Sterna dougallii) overlap with intense solar radiation and the presence of tropical cyclone and they prefer nest structure with vegetation or rock walls, as these may provide concealment to the surrounding weather. The objectives of this study were to examine the effect of nest structure on the nest microclimate and hatching success. In addition to nest structures, the effect of nest materials and parental incubation behavior on microclimate were also investigated. Results showed that the average temperature of vegetation-removed nests was higher than that of the control group. Rock walls seemed to prevent moisture formed from dew and rain. Incubation behavior can prevent eggs from overheating. However, there were no differences in parental thermal behavior and hatching success between nest types. To sum up, vegetation next to the nest can prevent the eggs from overheating while parents were temporarily absent. Parental incubation can insulate the eggs from surrounding weather stresses, and compensate the negative effect of nest structure with harsh conditions.

Heat stress affects pig growth performance, carcass
composition, and immune status. The present study was conducted to
evaluate the effects of heat stress and adding bacitracin methylene
disalicylate (BMD, 30g/ton) to a 10% DDGS commercial diet on growth
performance, carcass characteristics, physiological parameters,
small intestine morphology, and hindgut volatile fatty acid (VFA)
production of finishing pigs. Four groups of 32 finishing pigs (n =
128) with initial BW between 80 to 90 kg were used in this study.
Pigs were randomly assigned to diets and environmental temperature
treatments in a 2 x 2 factorial arrangement. Pigs were fed a
control (CON) or BMD (30g/ton) diet and exposed to a constant
thermal neutral temperature (23°C) or cyclical heat stress
conditions (37°C from 10:00 to 19:00 and 27°C from 19:00 to 10:00)
in environmental chambers for a 28-d experimental period. Pigs
housed under heat stress conditions had significantly lower average
daily gain (ADG, P < 0.0001), average daily feed intake (ADFI, P
< 0.0001), gain:feed (G:F, P < 0.001), and higher average
daily water intake (ADWI, P = 0.03), compared with pigs housed in
the thermoneutral environment. Supplementation of BMD in the diet
did not improve growth performance of pigs. Average daily gain
tended (P = 0.07) to be lower for pigs fed the BMD diet, while
ADFI, G:F, and ADWI were not affected by dietary treatment. Carcass
characteristics did not differ between dietary treatments. However,
pigs assigned to the heat stress environment had lower live BW (P
< 0.0001) and lower hot carcass weight (P < 0.0001) than pigs
housed in the thermal neutral environment. Dressing %, 10th rib
back fat depth, loin eye area, and lean % were not affected by
temperature treatment. Saliva cortisol concentration did not differ
between dietary treatments during the experimental period, but the
initial level was lower (P < 0.05) for pigs fed the BMD diet.
Heat stress led to an increased (P < 0.05) level of saliva
cortisol on d 1, but no effects were observed on the following
days. Serum haptoglobin concentration was not different between
dietary treatments, while heat stressed pigs showed a higher (P
< 0.05) level of haptoglobin on d 1, and levels tended to remain
higher (P < 0.1) on d 13 of heat stress. Cytokines IL-1β and
TNF-α were not affected by heat stress, but pigs fed the BMD diet
had an initial lower (P < 0.0001) level of serum IL-1β, and
tended to be lower (P < 0.1) on d 13 of heat stress as compared
to pigs fed CON. Small intestine morphology was not affected by
temperature treatment, but pigs fed the BMD diet tended to have
greater (P = 0.07) villi height at duodenum, and greater crypt
depth at duodenum (P = 0.09) and jejunum (P = 0.07), respectively.
Dietary treatment did not affect VFA production in the cecum, while
pigs housed under heat stress conditions tended to have less
propionate (P = 0.08) concentration,…
