▼ Understanding the enzymatic activity in ruminant digestive systems is essential for securing adequate growth, reproduction and overall metabolism. In order to evaluate the impact of various nutritional sources and dietary strategies on enzymatic activity, five experiments were designed. Experiment 1 examined the influence of nutrient restriction and melatonin supplementation on maternal and fetal pancreatic development. Experiment 2 explored various phases of the reproductive cycle and the impact of intravenous arginine infusion amid differing levels of feed intake. Experiment 3 determined the effectiveness of realimentation during advancing stages of gestation. Experiments 4 and 5 examined the impact of variable rations on ruminal pH, NH3, VFA, total gas and methane concentration and enzymatic activity in steers consuming rations of fine- vs coarse-rolled corn and 20% vs 40% DDGS (Experiment 4) and corn vs barley based diets with low- vs moderate-oil DDGS (Experiment 5). Overall, nutrient restriction caused reduced BW, pancreatic mass and pancreatic enzyme activity in mature animals. In Experiment 1, the addition of dietary melatonin diminished the impact of nutrient restriction on maternal pancreatic mass and α-amylase activity while reducing the secretion of insulin and size of insulin-containing cell clusters. Fetal pancreatic enzymes were unaffected by treatment, however, pancreatic morphology exhibited greater insulin-containing cell cluster size in fetuses from adequately fed dams. In Experiment 2, arginine infusion did not alter pancreatic exocrine or endocrine function during the various luteal stage phases. In Experiment 3, realimentation during different stages of gestation decreased the impact of reduced feed intake and, in some cases, allowed for compensatory gain of the exocrine pancreas. The maternal and fetal endocrine pancreas was unaffected. Mature animals had greater changes in pancreatic exocrine secretions whereas fetuses differed mainly in endocrine function as a result of improper nutritional status. Comparison of pancreatic tissue revealed a greater quantity, and larger size, of insulin-containing cell clusters in fetuses which appear to separate as the animal matures. Differences in rumen enzymatic activity was found in Experiments 4 and 5, however, despite changes in lag time of gas production or ruminal degradation rates, the concentration of greenhouse gases (CH₄ or CO₂) produced were unaffected.

▼ The overall objective of this study was to determine if the level of growth promotant technology used among production systems influence animal and carcass performance, meat quality, production economics, the environmental impact, and determine consumer preferences and perception. Angus Х Simmental steer calves (n =120) were stratified by birth date, birth weight, and dam age in a completely randomized design and assigned to one of four treatments: 1) no antibiotics (NA, receiving no technology); 2) non-hormone treated (NHTC, fed monensin and tylosin); 3) implant (IMPL, administered a series of three implants), and 4) implant plus fed a beta-agonist (IMBA, administered the same implant strategy as IMPL plus, fed ractopamine-HCI for the last 30 d prior to harvest). Animal weight, production expenses, and environmental factor data were collected from the production segments including: cow-calf, backgrounding, and finishing. During the finishing segment, animal feed intake, average daily gain (ADG), and efficiency was obtained. Carcass meat quality and yield performace was assessed. Striploins were collected for analyses post fabrication. Steaks were designated to specific postmortem aging periods, utilized for Warner-Bratzler shear force (WBSF), crude fat, and consumer sensory analyses. The consumer analyses evaluated beef production system information undisclosed and disclosed or simiply, without and later with information to assess palatability only, perception only, and perception plus palatability among untrained consumer panelists. IMPL had the greatest (P < 0.01) ADG and gain to feed (G:F). The final calculated body weight and hot carcass weight was similar (P > 0.05) and heavier (P < 0.01) for IMPL and IMBA in comparison to NA and NHTC, which were similar (P > 0.05). The actual branded carcass value was similar ( P > 0.01) for NA and IMPL and greater (P < 0.05) than NHTC and IMBA, which was similar (P > 0.05). Excluding the cost of the calf, production costs were similar (P > 0.05) and lowest (P < 0.05) for NA and IMPL, NHTC was intermediate (P < 0.05), and IMBA had the greatest ( P < 0.05) production cost. Net return was similar (P > 0. 01) between NA and IMPL, which was greater (P < 0.01) than NHTC and IMBA, which were similar (P > 0.01). In the environmental analysis, IMPL reduced GHG (CO₂e/kg HCW) emissions by 8%, energy use (MJ/kg HCW) by 6%, water use (kg H₂O/kg HCW) by 6%, and reactive N loss (g N/kg HCW) by 6%. The IMBA reduced GHG emissions by 7%, energy use by 3%, and reactive N loss by 1%. Meat quality analyses for marbling score and crude fat among NA and NHTC did not differ (P > 0.05) but were greater (P < 0.05) than IMPL and IMBA, which were similar (P > 0.05) and lower in crude fat. Steaks from NA and NHTC did not differ (P > 0.05) for WBSF though were more tender (P ≤ 0.05) than…

▼ Given the limited knowledge surrounding calf-rearing systems a series of studies were developed to address some of the aspects regarding colostrum and whole milk (non-saleable or hospital milk) physical process (Chapter 1), supplementation of trace minerals (Chapter 2), non-antimicrobial alternatives to prevent and control neonatal calf diarrhea (Chapter 3 and 4), to evaluate antimicrobial metaphylactic interventions in high-risk group of animals (Chapter 5), and finally to determine if pulmonary lesions in dairy heifers at weaning were associated with survival and reproductive performance (Chapter 6). Alternatives to heat-treatment of colostrum and non-saleable milk using ultraviolet light herein explored showed decreased levels of immunoglobulins in colostrum. Ultraviolet light and heat treatment decreased microorganism contamination. However, colostrum and non-saleable milk treatments were not associated with calf survivability, incidence of diseases (diarrhea and pneumonia), and average daily weight gain during the pre-weaning period. Injectable trace minerals supplementation improved leukocyte function and oxidative stress levels in dairy calves. However, these benefits did not translate to improved growth performance and health status for dairy calves in the first 60 days of life. Enteric-coated crofelemer extract, a natural-product with anti-secretory properties exhibited a significant increase in fecal dry matter in diarrheic neonatal calves in a challenge study. Furthermore, when the natural extract was administered prophylactically for the first two weeks of life, milk fed calves experienced significantly fewer events of diarrhea and reduced use of fluid therapy when compared to non-treated calves. A metaphylactic intervention using synthetic long acting macrolide significantly decreased the combined incidence of respiratory disease and otitis in high-risk group-housed replacement heifers during the pre-weaning period. Finally, nulliparous heifers suffered consequences from lung consolidation detected at weaning through a decrease in reproductive performance and an increase in culling risk. There are many important aspects on prevention and treatment of diseases affecting replacement dairy heifers. Strategically, different approaches can be used to improve replacement heifers’ health and performance.

▼ Dry lots, or small paddocks bare of vegetation, are commonly used to manage over- conditioned equids in order to restrict the diet by offering hay lower in digestible energy and non-structural carbohydrates (NSC) compared to unrestricted pasture access. However, the lack of vegetation in dry lots often caused by overgrazing and heavy traffic has been associated with negative environmental impacts such as soil erosion. Turfgrasses may be suitable as ground cover in dry lots because they are tolerant of traffic and close mowing (e.g. grazing) and may be low to moderate in both yield and NSC. The objective of this body of work was to 1) characterize the prevalence of over-conditioned equids in MD and whether dry lots were being used for their management, and 2) to assess the relative traffic tolerance, nutritional composition, and palatability of commercially available seeded cultivars of cool- season (CS) and warm-season (WS) turfgrasses for their potential use on horse farms. An online survey of licensed stable operators revealed that ~ 40% of horses in MD were over-conditioned and feeding hay in dry lots was a preferred practice despite requiring more maintenance and management time. Two additional studies evaluating wear tolerance of 8 CS and 6 WS cultivars exposed to either no, low, or high simulated horse traffic found that soil compaction increased as treatment level increased in CS and WS traffic trials (P <0.0001). Persistence was reduced in response to traffic in CS cultivars (P = 0.0003), but not in WS cultivars. Overall, tall fescue and zoysiagrass cultivars were most traffic tolerant, but only zoysiagrass had a more ideal NSC concentration. In the final study, horses exhibited no grazing preference among CS cultivars, whereas among WS cultivars they prefered common bermudagrass and crabgrass (P < 0.02). Several cultivars, including Maestro and Regenerate tall fescue, Zenith zoysiagrass, and Riviera bermudagrass cultivars were closest to meeting desired goals of being traffic tolerant, moderate in yield, and relatively low in NSC, and are thus recommended to be evaluated in future studies for on-farm persistence in dry lots and heavy use areas and for long-term effects of grazing by equids.

▼ Livestock production in general is a very small contributor to GHG emissions. However, swine producers will continually be faced with a series of challenges to minimize the environmental impact of swine production. The main objectives of the the studies in this thesis were to evaluate the effects of reducing dietary CP with the supplementation of synthetic AA and the effects of feeding diets with or without antibiotics on manure generation and excretion of N and C. In Exp. 1, thirty-two barrows were used in a metabolism study to evaluate the effect of feeding reduced CP, amino acid (AA) supplemented diets on nutrient excretion. Pigs were assigned to one of four dietary treatments: 1) Control: Corn-SBM-DDGS diets with no synthetic AA, 2) 1X reduction in CP, 3) 2X reduction in CP, and 4) 3X reduction in CP. Diet 4 was balanced on the 7th limiting AA, phenylalanine. Diets 2 and 3 were then formulated to have a stepwise reduction in CP between Diets 1 and 4. Diets 2-4 were supplemented with synthetic amino acids as needed to meet amino acid needs based on NRC 2012 AA minimum ratios for the 7 age phases tested. Low-CP AA supplemented diets significantly reduce N excretion by up to 45%. In addition, VFA concentrations were reduced between 9-17% when dietary CP content was reduced up to 3X levels. Overall fecal C excreted (g/pig/d) was greatest for the lowest CP (3X), largely due to the % C digested being the lowest for that diet. Both DE and ME, were linearly (P < 0.0001) decreased by approximately 6 and 5% respectively with increasing reductions in dietary CP. In Exp. 2, seven hundred twenty-three pigs were placed into eleven identical, environmentally controlled rooms for a wean-to-finish study. Pigs were allotted to one of two dietary treatments: 1) Control: Corn-SBM-DDGS diets with Antibiotics, and 2) Antibiotic Free; treatment 1 less the antibiotics but with alternative supplements. Diets were fed in nine dietary phases. There was a tendency for greater final BW and BW gain per manure pit when pigs were fed the control antibiotic treatment. No significant differences were observed between the two dietary treatments for manure volume (L), manure volume per kg BW gain, DM (g/kg BW gain), N (g/kg BW gain), and AmmN (g/kg BW gain). Manure pH tended to be lower for pigs fed the antibiotic free diet (P < 0.06) compared to the control diet. There were no differences observed for manure total C (kg), manure C per kg BW gain, manure C g/pig/d, and manure C g/pig wean-to-finish. In summary, Exp. 1 low CP diets with synthetic AA supplementation result in lower DE and ME values and C digestibility for the lowest CP diets, but significantly reduce N and VFA excretions. In Exp. 2, the antibiotic free diets had similar manure nutrient excretion and generation with lower manure pH which may affect transformation of N2O during manure land application. The adoption of technologies like these evaluated in this thesis will be of the utmost importance in remaining proactive in finding a way to meet the demands of a growing world… Advisors/Committee Members: Brian T Richert, Brian T Richert, John S Radcliffe, Brad C Joern, Tamillee Nennich.

▼ The objectives of this study were to determine the apparent metabolizable energy (AME), nitrogen corrected AME (AME_n) of soy protein concentrate (SPC), and standardized ileal amino acid digestibility (SIAAD) of (SPC) and dehulled soybean meal (SBM) in broiler and turkey poults. Soy protein concentrate and SBM was the only source of CP in their respective semi-purified diets used for estimating SIAAD in 7 and 21 d-old broiler chicken and turkey poults. Two experiments (Exp 1 and 2) were conducted with 6 replicate cages of 20 (d 7) and 6 (d 21) birds/cage. In Exp.1, experimental diets containing 0, 7, 14, and 21% of SPC replaced the energy contributing ingredients in the diet. Excreta were collected from d 5 to 7 and d 19 to 21, frozen, and dried. In Exp. 2, two semi-purified diets were formulated to contain 20% CP. Experimental diets were fed for 5 d (d 2 to 7) and (d 16 to 21) and ileal digesta was collected on d 7 and 21.In Exp.1, increasing dietary SPC had no effect on AME or nitrogen-corrected AME (AME_n) at 7 d of age in broiler chicken. However, increasing SPC linearly improved AME (P=0.002) and AME_n (P=0.019) at 21 d. The AME and AME_n for SPC containing diets based on linear regression was 2,784 and 2,622 Kcal/Kg at 7 and 3,676 and 3,473 kcal/kg at 21 d, respectively. In Exp. 2, apparent DM and N digestibility for SPC and SBM based diet increased (P=0.0001) from d 7 to 21. There was a soy source by age interaction (P<0.05) for SIAAD, where SBM digestibility increased only slightly from d 7 to 21, while digestibility of SPC increased quite remarkably. In turkey poults, increasing SPC linearly improved AME and AME_n on d 7 and 21 (P ≤ 0.028). The AME and AME_n for SPC containing diets based on linear regression was 3,385 and 3,152 at 7 and 3,666 and 3,409 on d 21, respectively. In Exp. 2, apparent DM digestibility for SPC-and SBM-based diets were not significantly different between ages (P >0.10) and diets (P=0.097). Apparent N digestibility was different between ages (P<0.05) but not different between diets (P>0.10) with no age by diet interaction. The SIAAD were not significantly different between ages and diets. ^ In conclusion, replacing the energy contributing ingredients of a corn/SBM basal diet with graded levels of SPC resulted in significant improvement in AME and AME_n in both broiler chicks (21d) and turkey poults (7 and 21d). SBM has a slightly higher SIAAD compared to SPC in broiler chicks and the digestibility of DM, N, and amino acids were substantially less at 7 versus 21 d of age. In turkey poults, the amino acid content of SPC was well utilized by the young poults compared to the broiler chicken. Nevertheless, SPC has considerably higher energy and amino acid density than SBM in both species. Advisors/Committee Members: Todd J Applegate, Todd J Applegate, Jon Schoonmaker, Tamilee Nennich.

▼ The objective of this research was to compare different expressions for the digestibility of Ca in both pigs and chickens, and to determine the true total tract digestible (TTTD) Ca requirement for 10- to 20-kg and 20- to 40-kg pigs. In the first study, two experiments were conducted to compare apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of Ca in pigs. In Exp. 1, three semi-purified diets with soybean meal, canola meal or sunflower meal as the sole source of Ca were formulated. Eighteen cannulated pigs (initial BW = 66 ± 5 kg) were assigned in a randomized complete block design to 3 treatments and 6 replicates per treatment. Results indicated that for either Ca or P, the ATTD was not different from AID in three diets. In Exp. 2, diets with four Ca concentrations were formulated with calcium carbonate as the Ca source. Sixteen cannulated pigs (initial BW = 73 ± 4 kg) were assigned in a randomized complete block design to 4 treatments in 2 experimental periods. The results indicated that the ATTD of Ca was not different from AID for all diets, and the Ca digestibility was not affected by the dietary Ca concentration. The results of these two experiments indicated that both AID and ATTD can be used to describe the digestibility of Ca for growing-finishing pigs. Total tract digestibility was used to express digestibility of Ca in later studies. A second series of studies was conducted to decide whether ATTD or TTTD should be used to estimate Ca digestibility of limestone and dicalcium phosphate (DCP). Two pig experiments were conducted to determine the ATTD and TTTD of limestone and DCP, and their additivity in a semi-purified diet for pigs. In Exp. 1, forty eight barrows with an average initial BW of 19.2 ± 1.1 kg were assigned to 1 of 6 dietary treatments in a 2 × 3 factorial arrangement of two Ca sources, including limestone or DCP, with three dietary Ca concentrations each. Diets were fed for a 5-d adjustment period followed by a total collection period of 5 d. The results indicated that the increased dietary Ca concentration linearly increased Ca intake, digested and retained, but did not affect the ATTD of Ca when using limestone and DCP as Ca sources. In Exp. 2, seventy-two barrows with an average initial BW of 20.8 ± 1.3 kg were used to test the additivity of TTTD for Ca in limestone and dicalcium phosphate (DCP) in pigs. All pigs were assigned to 1 of 9 dietary treatments in a 3 × 3 factorial arrangement of three Ca sources, including limestone, DCP, or a mixed diet at a ratio of 1:1; and three dietary Ca concentrations. Feeding and sample collection procedures were as in Exp. 1. The results indicated that the average ATTD were 66.46, 70.34, and 69.32% for limestone, DCP, and their mixed diet, respectively. By regressing daily digested Ca against daily Ca intake, the TTTD of Ca was determined at 70.06, 76.42, and 73.72% for limestone, DCP, and their mixed diet, respectively. The endogenous losses of was estimated…

▼ In pigs, litter size and developmental competence are crucial for successful production of the meat product. However, the ability of the placenta to produce a developmentally competent pig is vital in the production of meat animals. Placental efficiency (fetal weight divided by placental weight) has been studied as a measure of placental function and litter size. Selection for increased placental efficiency has been shown to increase placental efficiency as well as litter size. Furthermore, formative muscle development occurs entirely during gestation, so that the number of muscle fibers the pig is born with is reflective of the number of fibers of the pork product after harvest of the animal. Following parturition, hyperplasia no longer occurs and muscle growth is entirely hypertrophic. The ratio of secondary to primary muscle fibers is an important marker for pork quality as well. The number of fibers and the size to which the muscle fibers grow, particularly the secondary muscle fibers can affect pork quality. Additionally, the growth of the secondary muscle fibers can be affected by environmental conditions (e.g., housing, stress). As shifts in industry trends take place, the effects these changes will have on the development of the fetuses of pregnant sows and gilts need to be studied. The objectives of the work here were: 1) to determine the effect of placental efficiency on in utero muscle development, 2) to determine the influence of placental efficiency on the postnatal growth performance and muscle development of pigs at market weight, and 3) to investigate the effects of exercise of second parity sows during gestation on fetal development and metabolism. For the first objective, pregnant females were ovariohysterectomized at day 95, fetal blood and muscle samples were collected and used to determine fetal metabolite concentrations and muscle fiber number and size, respectively. On day 95 of gestation, primary and secondary muscle fiber size of both loin and ham muscle samples were increased in fetuses of low placental efficiency compared to high placental efficiency fetuses. For the second objective, pregnant females farrowed naturally and pigs were caught, umbilical cords tagged and ears notched so placental efficiency could be determined following expulsion of placentae. Pigs were then fed to market weight (120 kg) and slaughtered. Muscle samples were collected following a 24 hour chill and used to determine muscle fiber number and size. Placental efficiency at birth decreased the secondary to primary ratio of muscle fibers in loin muscle samples in low placental efficiency pigs at market weight. Finally, in accordance with the third objective, second parity sows were exercised from day 44 to day 94 of gestation. On day 94, sows were ovariohysterectomized and euthanized. Fetal blood samples and muscle samples were collected to determine fetal metabolite concentrations and fetal muscle fiber number and size, respectively. Exercise during gestation decreased fetal body and muscle weights as well as… Advisors/Committee Members: Matthew E. Wilson..

▼ Obesity causes a multitude of metabolic issues in the horse, yet stepwise alterations in glucose and lipid metabolism, mitochondrial capacity and oxidant status during weight loss have yet to be analyzed. Skeletal muscle contains subsarcolemmal (SSM) and interfibrillar (IFM) mitochondria, which respond differently to physiological stimuli, impacting tissue and whole body oxidant status. We hypothesized that 8 light-type horses would display improvements in skeletal muscle mitochondrial subpopulation function and decreases in circulating oxidant status markers during weight loss from an obese (7 to 8) to moderate (5) body condition score (BCS). Additionally, we hypothesized improvements in morphometric measurements, circulating metabolic markers, along with glucose tolerance and insulin sensitivity would also be seen. Change in BCS and percent weight loss were related to decreases in all morphometric measurements (p<0.05) except for abdominal circumference (p<0.10). Measurements of body composition also decreased with regard to both weight loss parameters (p≤0.001). Circulating markers of lipid metabolism evaluated from non-fasting samples revealed no changes in non-esterified fatty acid (NEFA) or triacylglyceride concentration, yet ex vivo lipolysis media was decreased in response to weight loss (p=0.07) and BCS change (p=0.01). Insulin sensitivity calculated from baseline and post-weight loss intravenous glucose tolerance tests was improved after weight loss and corresponding BCS decline (p≤0.05) while the disposition index, reflecting beta-cell responsiveness, also increased due to weight loss (p=0.09). Plasma nitrate decreased in response to BCS reduction (p=0.06) and percent weight loss (p=0.06), whereas erythrocyte total glutathione (p=0.06) concentration increased with decreasing BCS, signifying improvements in oxidant status. Mitochondrial electron transport chain complex I and IV displayed greater activity in SSM than IFM (p≤0.05), while I, III, and IV in SSM had decreased activity due to BCS change and percent weight loss (p≤0.01). Interactions between SSM and IFM complex IV activity and both weight loss markers (p<0.05) were displayed. Citrate synthase activity, indicating mitochondrial number, was greater in SSM than IFM (p<0.0001) but remained unchanged with weight loss parameters. Lipid peroxidation was decreased due to BCS change (p=0.01) and weight loss (p=0.02), with greater concentration in SSM, but a larger decrease in IFM (p≤0.05). Alterations in complex activities and lipid peroxidation suggest IFM are more affected by weight loss, with large contributions from complex IV byproducts. Mitochondrial component flexibility may contribute individually to development and disease propagation along with athletic performance of the equine athlete. Lack of changes in circulating markers along with minimal changes in minimal model parameters suggest that while horses were obese, metabolic function was conserved. Further evaluation of metabolically healthy but obese horses may provide insight… Advisors/Committee Members: Kimberly M. Barnes, Stephen E. Alway, John M. Hollander.

▼ There are various methods of processing avian diets. However, the two common methods of processing include grinding, batching, mixing, and feeding the resultant mash that is not thermally processed, extrusion processing, baking, and steam conditioning and pelleting. The method of processing utilized can greatly affect nutrient availability, therefore affecting the health and/or performance of the avian. The objective of the first study was to transition cockatiels (Nymphicus hollandicus) that were housed in a controlled experimental setting, with a standardized transition strategy, using two different commercially available cockatiel diets that were advertised as nutritionally complete. The transition strategy consisted of gradually increasing the ratio of complete diet to seed-based diet over a 12d period. True amino acid digestibility was determined for each complete diet and demonstrated that both diets contained highly digestible amino acids. Fourteen cockatiels individually housed in acrylic cages were transitioned to one of the complete diets (Diet A or B). Diet A and B differed in ingredient composition, ingredient particle size, analyzed nutrients, and method of processing (baked or extruded). It may be speculated that cockatiels were more accepting of baked Diet A during transition and Diet A more efficiently maintained BW. The objective of the second study was to determine the effects of pelleting, inclusion of a Bacillus derived keratinase, and bird sex on broiler performance. The keratinase was batched and mixed prior to steam conditioning and pelleting and therefore must be thermally stable to demonstrate efficacy. This study consisted of a 2 x 2 x 2 factorial arrangement of treatments in a randomized complete block design; there was either a ground pelleted or mash diet with or without keratinase supplementation fed to a pen of either male or female Cobb x Cobb 500 broiler chicks. Mash feed was short-term conditioned to a temperature of 82°C and extruded through a 38.1 x 4.76 mm pellet die using a 40 HP California Pellet Mill. Males had enhanced broiler performance as compared to females. The thermal conditions of the pelleting process decreased broiler performance likely due to decreasing nutrient availability. Keratinase activity was reduced due to thermal conditions of pelleting that may have contributed to the lack of enzyme efficacy with respect to broiler performance.

▼ Lysine is thought to be oxidized primarily by lysine alpha-ketoglutarate reductase (LKR) and saccharopine dehydrogenase (SDH), which are restricted to the mitochondrial matrix. Lysine is presumably transported through the plasma membrane by isoforms(s) of a cationic amino acid transporter (CAT). Although the mechanism(s) of lysine transport through the inner mitochondrial membrane is not known, it is presumptively transported by one or both mitochondrial "ornithine transporters" (ORC-1/ORC-2). Tissue distribution of LKR and the mechanism(s) responsible for alterations in hepatic lysine catabolism in swine are unclear. Also, the roles of the alternative pathways of lysine degradation, the L-amino acid oxidase-dependent (LAAO), in poultry, and the lysyl oxidase-dependent pathway (LO), in mammals and poultry, have not been established. Genetic effects on lysine degradation were evaluated throughout the production-cycle in 2 strains of commercial turkey. Hepatic LKR activity (P<0.05), LKR mRNA (P<0.01), SDH activity (P<0.05), lysine oxidation (LOX, P<0.0001), LAAO activity (P<0.05), LO activity (P<0.01) L-amino acid oxidase (P<0.0001), and CAT1 mRNA abundance (P<0.05) differed throughout the production cycle. Differences in indices of lysine catabolism due to strain in these 2 commercial lines of turkey were not detected. The LAAO and LO activities represented only 0.21 and 0.03% of the activity of enzymes involved in the saccharopine-dependent pathway. These data support that the saccharopine-dependent pathway is the predominant pathway of lysine degradation in turkey liver and that indices of hepatic lysine catabolism vary throughout the production cycle. Next, studies were conducted in swine to characterize the tissue distribution and evaluate possible mechanisms of alterations in lysine degradation. In growing pigs, LKR activity (P<0.001) was highest in liver, intestine and kidney samples and SDH activity (P<0.0001) and LKR (P<0.0001) and SDH mRNA (P<0.0001) were highest in liver. Interestingly, tissue distribution of LKR activity was correlated with ORC-1 and ORC-2 mRNA (r2=0.32, P<0.05 and r2=0.41, P<0.05, respectively). Average LO activity across tissues represented only 0.5% of the activity of enzymes involved in the saccharopine-dependent pathway. These data indicate that extra-hepatic tissues play a role in whole-body lysine degradation, ORC transporters may play a role in the transport of lysine into the mitochondrial matrix for its catabolism, and the saccharopine-dependent pathway is the predominant pathway of lysine degradation in pig tissues. To further investigate the role of ORC in lysine catabolism and to discern the mechanisms responsible for alterations of lysine catabolism, weanling pigs (n=35) were fed either a control (C), high protein (HP), low protein (LP), high lysine (HL) or low lysine (LL) diet. Liver LKR activity (P<0.05) and AASS protein expression (P<0.01) were reduced in pigs consuming the LL diet compared to C. Liver SDH mRNA expression was reduced (P<0.08) with the consumption of the LL… Advisors/Committee Members: Kenneth P Blemings.

▼ Successful commercial turkey production requires proper genetic strain selection to optimize live performance and profit. In addition, sustainable practices relative to manure disposal are essential due to perceptions that land application of poultry manure is a primary contributor to watershed eutrophication. The objective of our research was to assess genetic strain and finisher diet non-phytate phosphorus (nPP) level effects on large tom performance and litter composition using a research facility that mimics commercial production. Experiments were 2x2 factorial designs utilizing 2 strains (Nicholas and Hybrid) and 2 levels of dietary nPP (normal and low) in finishing diets. Two experiments of similar concept and design were conducted in sequence. In experiment (Exp) 1 Hybrid Converter and Nicholas 88x700 strains were compared, and dietary nPP was reduced during the last finisher diet [calculated percent nPP: normal (0.37) and low (0.31)]. In Exp 2, Hybrid Converter and Nicholas TP5 strains were compared, and dietary nPP was reduced in the last 2 finisher diets [calculated percent nPP: normal (0.58) and low (0.55) in the finisher 1 diet, and normal (0.40) and low (0.38) in the finisher 2 diet]. Live performance measurements were recorded from d 1-136 and from d 1-126 for Exp 1 and 2, respectively. Liver enzyme assays associated with lysine degradation were quantified and litter phosphorus (P) levels were determined. In Exp 1, both strains had similar ending weight (EW). The Hybrid Converter strain had improved feed conversion ratio (FCR) as compared to the Nicholas 88x700 strain. The initial enzyme of the primary pathway of lysine oxidation/degradation, lysine alpha-ketoglutarate reductase (LKR), had greater activity in Nicholas compared to Hybrid toms. Changes in dietary nPP in the finisher diet did not affect performance or litter P, thus indicating potential to decrease feed cost but not environmental impact. In Exp 2, Nicholas TP5 had greater EW but increased FCR as compared to Hybrid Converter toms. However, regression equations that standardized strain EW, predicted a decreased time of production and FCR for Nicholas TP5 toms. Hybrid Converter and Nicholas toms did not differ in LKR activity; although, a decrease in activity over time was observed. Manipulation of dietary nPP level did not affect tom performance. However, the low nPP diet decreased total litter P, thus indicating potential to decrease feed cost and environmental impact. Advisors/Committee Members: Josephh Moritz..

▼ Early pregnant ewes, 5 or 6 day post coitus (dpc) were used as a model to study early embryonic loss via gram-negative bacterial infections, such as mastitis. Ewes 5/6 dpc were injected with a gram-negative bacteria cell wall component, lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-&agr;), to induce an innate immune system acute phase response (APR). The induction of the APR and its reactant molecules, such as TNF-&agr; and acute phase proteins (APP), haptoglobin (Hp) and serum amyloid A (SAA), were initiated to study their effects on embryonic loss. In addition, ewes were also injected with LPS plus dexamethasone (Dex) to study its effects on indirectly altering embryonic loss through toll-like receptor 4 (TLR4). Thirty-eight Dorset x Texel ewes were synchronized for estrus and bred by fertile rams. On 5 or 6 dpc, ewes were assigned to one of four treatment groups per pen and received via the jugular vein either 2.5 mL of 0.1% BSA/PBS (controls, n=9), 2.5 mL of 2.5 &mgr;g/kg of LPS (n=9), 5 mL of 1 &mgr;g/kg of TNF-&agr; (n=10) in two bolus injections given thirty minutes apart, or 2.5 mL of solution containing 2.5&mgr;g/kg of LPS after having received 3.5 mL of solution containing 0.14 mg/kg BW im dexamethasone (Dex, n=10) at -12 and 0 hours. Plasma was collected from the jugular vein before challenge, followed by post challenge samples every 30 minutes until 3 hours and every hour until 12 hours, and once at 24, 36, and 48 hours. In addition, behavioral changes and rectal temperature were also documented before challenge injections followed by every hour for 12 hours post challenge, and processed soon after collection for total white blood cell counts, and plasma was stored at -80°C. A white blood cell differentiation was determined by staining and counting one hundred cells classified among monocyte, lymphocyte, eosinophil, neutrophil, or basophil cell types. Assays were conducted for APR reactants, TNF-&agr;, SAA, Hp. Jugular samples were collected in EDTA treated tubes on days 9 or 10 and 25 or 26 pc for determination of concentrations of progesterone (P4) for evaluation of luteal function. At day 25 or 26 pc, detection for pregnancy was examined. Intoxication of day 5 or 6 pregnant ewes treated with LPS, TNF-&agr;, or LPS+Dex did not differ in pregnancy status among treatment groups (p=0.298) and more control ewes plus ewes treated with TNF-&agr; tended to remain pregnant than ewes treated with LPS or LPS+Dex (p=0.05). Total white blood cell count differed by treatment (p<0.0001), hour (p<0.001), and treatment by hour (p<0.0001). There was an effect of treatment on lymphocytes (p<0.0001) and monocytes (p=0.0103). There was an effect of hour on lymphocytes (p<0.0001), neutrophils (p<0.0001), and monocytes (p<0.0001). There was an effect of treatment by hour on neutrophils (p=0.0047). There was no difference in Hp concentration by treatment (p=0.0859), hour (p=0.4317), and treatment by hour (p=0.0996). There was a difference in SAA concentration by treatment (p<0.001), hour (p<0.001), and… Advisors/Committee Members: Dr. Robert Dailey, Dr. Scott Bowdridge, Dr. Ida Holaskova.

▼ Silver carp (Hypophthalmichthys molitrix) is one of the main freshwater fish species with a high nutritional value; however, it is hard to process the fish due to its boney carcass. Therefore, isoelectric solubilization and precipitation (ISP) processing was applied to headed gutted silver carp to separate the protein from the bones, scales, skin, fins, etc. Different solubilization strategies (pH 2.5, 3.0. 11.5 and 12.0) using organic acids, either acetic acid (AA) or a 30% formic and lactic acid combination (F&L), were applied during ISP and the different effects of treatments on the materials recovered from the initial silver carp were compared. The recovered carp proteins were then used to make protein gels similar to surimi with the use of standard food additives. To further assess the effect of using different solubilization pH values and organic acids on the protein quality of the recovered fractions, the functional, texture and color properties were analyzed.;Proximate composition of the recovered proteins showed that processing at basic pH using AA was most effective at removing impurities (i.e. bones, scales, skin, fins) (p<0.05) and the impurities were effectively removed from recovered lipids regardless of processing pH or acid type. Functional properties of gels made from protein recovered by ISP processing using organic acids as the processing acid had typical gelation characteristics. Moreover, it was seen that isoelectrically recovered carp proteins were not denatured and retained functionality. Thermal denaturation and dynamic rheology of the protein gels revealed that using AA under acidic conditions and F&L with alkali treatments yielded improved gel structure. In addition to that, color analysis presented data showing that gels made using F&L were whiter for all solubilization conditions (p<0.05) and were similar to the whiteness of Alaska Pollock surimi gels under acidic treatments. Texture analyses highlighted that gels made from protein solubilized at basic pH values had firmer texture (p<0.05) and were harder and more cohesive, gummy and chewy (p<0.05) than proteins solubilized under acidic conditions. Moreover, gels made from proteins recovered using AA as the processing acid under basic conditions had similar shear stress responses as Alaska Pollock surimi.;This research shows that organic acids have the potential to recover protein and lipid from otherwise hard to process fish by ISP processing. The gels made from recovered carp protein show similar or improved functional, texture and color properties compared to Alaska Pollock surimi depending on the treatment and might be used for the development of restructured fish products for human consumption.

▼ Using exogenous gonadotropins as part of an estrous induction protocol can have beneficial effects on fertility in ewes bred out-of-season. Few studies have evaluated the efficacy of P.G. 600RTM, a mixture of gonadotropins with FSH-like and LH-like activity, to increase fertility in anestrous ewes and, in particular, following pre-treatment with progesterone delivered via controlled internal drug releasing (CIDR) devices. The objective of this study was to evaluate the effects of P.G. 600RTM on reproductive success in progesterone-treated non-lactating anestrous ewes. Ewes, which had been separated from rams for at least one month prior to the beginning of the experiment, received CIDR inserts five days prior to introduction of rams. In the first experiment, ewes were assigned randomly to receive either a 3 mL injection of P.G. 600RTM [i.m., 240 IU equine chorionic gonadotropin (eCG) and 120 IU human chorionic gonadotropin (hCG)] at CIDR insert removal or no further treatment. In the second experiment, ewes were assigned randomly to receive either a 3 mL injection of P.G. 600RTM one day prior to insert removal or no further treatment. In experiment 1, incidence of estrus was significantly greater for treated ewes than control ewes, while prolificacy (number of lambs born per ewe lambing) tended to be higher in treated ewes. In experiment 2, treated ewes had significantly higher conception rates and pregnancy rates to first service and tended to have higher overall pregnancy rates than control ewes. A greater percentage of ewes lambed in the treated group than in the control group; however, prolificacy was not different between the groups. In addition, overall lambing rates in ewes treated with P.G. 600RTM were significantly higher than those of the control group. An injection of 3 mL of P.G. 600RTM (240 IU eCG and 120 IU hCG) one day prior to CIDR removal significantly increased reproductive success in progesteronetreated non-lactating anestrous ewes. Further, the gonadotropin injection was determined to be economically beneficial. Advisors/Committee Members: Marlon Knights..

▼ Broiler chickens reared in the United States are mainly fed corn-soybean based diets. Most of the phosphorus in these diets is bound to a molecule called phytate; this source of phosphorus is unavailable to the bird because they lack adequate amount of endogenous phytase enzyme. Since the 1990's exogenous phytase enzymes have been incorporated in broiler diets to liberate the phytate-bound phosphorus. These enzymes must be able to resist thermal denaturation associated with pelleting and maintain high efficacy in the bird. Most of the literature focuses on single aspects of phytase efficacy. More specifically, experiments evaluate phytase based on either in vitro retention or in vivo measures, but rarely are both considered simultaneously. Therefore, six experiments were conducted at West Virginia University to elucidate variable effects in order to demonstrate how to properly assess the efficacy of microbial expressed phytase variants. The authors believe that several testing experiments are essential to properly assess phytase and sequence is important. The following variables were considered: 1) in vivo assays using lead candidates in mash feed; 2) optimization of enzyme production based on a specific expression host; 3) in vivo dosing assay using the best enzyme/host combination; 4) in vivo assay using incrementally increased pelleting temperatures. In vitro activity was determined for each experiment and in vitro retention using increasing pelleting temperatures was determined for experiments 1 and 2. All experiments utilized Cobb 500 broiler chickens and included a standard curve, generated by feeding incrementally increased non-phytate phosphorus (nPP) via inorganic phosphorus. Linear and quadratic regressions of the standard curve were tested to determine nPP sparing effects. Four experimental phytases were determined from in vitro activity; two of the four enzymes were chosen after the in vivo assay using mash feed. These two enzymes were expressed in yeast and bacterial hosts. The best enzyme/host combination was chosen for in vivo testing at various doses. Finally the enzyme/host combination at an appropriate dose was pelleted at incremental temperatures for in vivo testing. The best enzyme expressed in the yeast host at 750 FTU/kg was found to perform similar to a positive control diet. However, conditioning temperature during pelleting decreased performance compared to mash feed despite similar in vitro activity.

▼ Resveratrol, a naturally occurring phytocompound is known to exert numerous health benefits including improved insulin sensitivity and glucose tolerance, along with decreased tissue damage due to reactive oxygen species (ROS). This compound is incorporated in a multitude of supplements targeted to performance horses, yet no research in an athletic equine model has been completed to date. Therefore, this study was performed to test the hypothesis that resveratrol supplementation would improve glucose tolerance and insulin sensitivity, while reducing oxidant damage in an exercising model. Six, healthy, fit aged (10.5+/-1.5yr, ~500kg) Quarter Horse geldings were assigned to three treatment groups in a Latin Square random crossover design with one week between crossovers. Horses either received no supplementation (control, C) or one of two treatments (T); low dose (L, 2.5g of trans-resveratrol) and high dose (H, 5g of trans-resveratrol) administered on a daily basis for 14 days. Body weights (BW), blood samples, and muscle biopsies were collected on day 0 and day 14 of each supplementation period. All horses were moderately exercised 3 times a week for 60 minutes with an average heart rate of 90 bpm. A frequently sampled intravenous glucose tolerance test (FSIGT) was conducted on day 10 of supplementation during each treatment period. Feed intake data was collected daily. Samples from day 0 and 14 were analyzed for thiobarbituric acid reactive substances (TBARS), while FSIGT samples were analyzed for plasma insulin and glucose. The null hypothesis was rejected when P<0.05, and trends were identified when P < 0.10. Minimal model analysis of FSIGT, along with evaluation of baseline inulin and glucose concentrations, and area under the glucose and insulin curve showed no effect of resveratrol supplementation (P > 0.05). Plasma TBARS was unaffected by resveratrol supplementation (P > 0.05) within this model. Body weight did not change due to T, yet contrast between C and T displayed trends toward increased feed intake as % BW of both hay and concentrate (P < 0.10). In conclusion, resveratrol supplementation in the moderately exercised horse does not improve insulin sensitivity or glucose tolerance, or overall lipid peroxidation. Increased feed intake displayed by T over C may have a potential application for a high performance animal. These observations display a need to further evaluate the effects of resveratrol in other equine models, and a more in depth assessment of resveratrol within the athletic horse.

▼ Residual feed intake (RFI) class differences in gut function and grazing intake were evaluated using 14 crossbred steer progeny of first parity dams with known RFI phenotypes and a commercially available Angus sire. Steers were housed in a drylot facility and fed a forage based complete feed ad libitum, a forage diet at maintenance (1.5% BW as fed), and a concentrate diet at maintenance in Exp. 1, 4, and 5 respectively. Voluntary DMI and solid and liquid passage rate were evaluated while grazing (Exp. 2 and 3, respectively). Plasma concentrations of albumin (ALB), urea nitrogen (UN), cholesterol (CHOL), glucose (GLU), triglycerides (TG), and VFA were assessed immediately pre- and at 3 h intervals for 12 h post-feeding as indicators of nutrient absorption in Exp. 1, 4, and 5 respectively. Rumen pH, ammonia (NH4), and VFA were evaluated 12 h post-feeding. Steers were classified as either positive (POS; n = 8) or negative ( NEG; n = 6) according to dam RFI (mean 0.46 kg TND/d; range -4.27 to 5.70 kg TDN/d). Rumen pH, ammonia, and VFA's did not differ based on RFI classification (P > 0.05) in any of the experiments. Plasma metabolite and VFA concentrations did not differ between RFI classes in Experiment 1 (P > 0.05); however, UN was greater in POS (12.80 vs. 12.14 mg/dL; P = 0.02) steers when fed a forage diet at maintenance (Exp. 4) and greater in NEG (16.74 vs. 15.42 mg/dL; P = 0.01) steers when fed a concentrate diet at maintenance (Exp 5). Plasma valerate and butyrate (P = 0.02 and 0.02, respectively) were greater in NEG steers in Exp. 1 and 5, respectively. Evaluation of RFI group differences by collection time revealed a significant (P = 0.04) interaction of RFI and Time for TG and plasma isobutyric acid in Exp. 1. Concentrations of TG were greater (P = 0.04) in NEG steers at 3 hours after feeding but did not differ at any other time points. Plasma isobutyric acid concentrations rarely differed from zero but were greater in POS steers 6 hours post-feeding. The opposite was true at 12 hours post-feeding. No other interactions between RFI and collection time were significant. Negative RFI steers consumed numerically 8.9% less DM per day while grazing than POS steers but did not differ in voluntary DMI (P = 0.74). Liquid passage rate was greater in NEG (7.16 vs. 6.32 % marker/hour; P = 0.04) steers but solid passage rate was not different (P = 0.88). These data indicate that RFI classification may be associated with variation in the regulation and absorptive capacity of the gastrointestinal tract. Advisors/Committee Members: Eugene E. D.

▼ Compelling clinical reports indicate that emotional/behavioral stress alone is sufficient to cause profound, but completely reversible myocardial dysfunction in selected individuals. A rodent cardiomyopathy model was previously reported by combining pre-natal and post-natal behavioral/restraint stress (Stress). A decrease in % FS (the ratio between the diameter of the left ventricle when it is relaxed and when it is contracted) by echocardiogram was previously reported, along with both systolic and diastolic dysfunction by catheter-based hemodynamics, as well as attenuated hemodynamic and inotropic responses to the beta adrenergic agonist, isoproterenol (ISO) in Stress compared with matched Controls. The p38mitogen-activated protein (MAP) kinase inhibitor, SB203580, both prevented and reversed the baseline reduction in systolic and diastolic dysfunction, as well as the blunted ISO response in cardiac myocytes from Stress animals in vitro and in vivo. p38 MAP kinase has been reported to be activated by oxidative stress. Previous work showed that the sulhydryl donor and substrate for glutathione, N-acetylcysteine (NAC), reversed myocardial dysfunction in 2 different genetic proteinopathy models (Syrian Hamster and Tat mouse). In the current studies, cardiac myocytes isolated from Stress revealed evidence of mitochondrial dysfunction and oxidative stress as indicated by decreased ATP concentration and decreased GSH/GSSG ratio, respectively. Stress cardiac myocytes also displayed blunted inotropic and [Ca2+ ]i responses to extracellular Ca2+ ([Ca 2+]out) and ISO (p<0.05, for each), as well as altered inotropic responses to the intracellular calcium regulator, caffeine (10mM),which causes sacroplasmic reticulum Ca2+ depletion (p<0.01). Treatment of cardiac myocytes with NAC (10-3 M) normalized calcium handling in response to ISO and [Ca2+]out and inotropic response to caffeine (p<0.01, for each). NAC also normalized the blunted inotropic response to ISO and Ca2+ (p<0.01, for each). Surprisingly, NAC did not reverse the changes in GSH, GSSG or GSH/GSSG ratio. These data indicate that NAC may reverse cardiac myocyte dysfunction by a glutathione-independent effect on intracellular calcium signaling. Elucidating the molecular mechanisms responsible for the salutary effects of NAC may provide novel insights into potential therapeutic targets for the reversal of myocardial dysfunction in patients with cardiomyopathies and heart failure.

▼ The objective of this study was to identify feed manufacture techniques that alter lysine availability as indicated by broiler performance in the finishing phase, diet furfural content, and true amino acid digestibility. Production rate, pellet die specification, and level of mixer-added fat (MAF) influence feed exposure to pellet die frictional heat and pressure that may alter chemical structure of ingredients. Lysine has been indicated as a nutrient with potential to be structurally altered, especially in the presence of heat and reducing sugars, as in Maillard reactions; decreasing nutrient availability. A practical diet containing 7.5% bakery by-product meal and 0.13% lysine HCl was formulated to 90% of the lysine recommendation by Cobb-Vantress to be below the perceived safety margin associated with breeder recommendations and best demonstrate lysine availability differences when manufactured and fed. This diet was utilized in a 2 x 2 x 2 factorial design that evaluated the main effects of production rate (0.5 or 0.8 tonne/hr), pellet mill die thickness (38.1 or 44.5 mm), and MAF level (0.5 or 3%) on feed manufacture, broiler performance, and processing yield. Two additional treatments: unprocessed mash and double pelleted (exposed twice to 0.5 tonne/hr production using a 4.5mm die after 0.5% MAF) were also manufactured and fed. All diets, excluding mash, were steam conditioned at 82°C and ground prior to feeding. Pellet mill electrical energy usage, pellet quality, and bulk density were increased with 0.5 tonne/hr production rate, 44.5 mm pellet die, and 0.5% MAF processing treatments (P=0.0001); indicating greater feed exposure to pellet die frictional heat and pressure. Bird performance and carcass characteristics were not affected by main effects (P>0.05); however, contrasts demonstrated that mash fed birds had decreased feed conversion ratio (FCR) compared with double pelleted fed birds, with birds fed diets from the factorial treatments being intermediate (P<0.05). To determine if the mechanism of action responsible for the FCR effects included lysine digestibility, diets were analyzed for furfural, an intermediate of the Maillard reaction pathway, and assessed for true amino acid digestibility using cecectomized roosters. Furfural concentration was not altered due to processing treatment (P > 0.05). In addition, no differences in lysine digestibility or the digestibility of any other tested amino acid were apparent (P > 0.05). Therefore, lysine availability, as assessed with this specific methodology, does not appear to be decreased due to pelleting. Advisors/Committee Members: Joseph S. Moritz..

▼ Effects of oxytocin on the ovine corpus luteum have been controversial for a number of years. The present study investigated the effects of atosiban, a combined oxytocin and vasopressin 1A antagonist, administered systemically to ewes on post estrus day 8 to 10. Atosiban was given in four bolus intravenous injections at 0, 60, 120 and 180 minutes with blood sampling every 15 minutes from -60 through 480 minutes. Concentrations of serum progesterone ng/ml were measured via radioimmunoassay. A log10 transformation of progesterone values was conducted to account for the heterogeneity of variance of the values. During the treatment interval (0 to 240 minutes), log10 concentrations of progesterone were lower in ewes treated with 20 mg (0.99) than in the 5 or 10 mg treated groups (1.00; P < 0.05). Control ewes (P < 0.0001) differed from ewes treated with atosiban (5, 10 or 20 mg). During times greater than 240 minutes (hours 4 to 24), log10 concentrations of progesterone decreased in control ewes (1.04) and were lower in the ewes treated with 5, 10 or 20 mg (1.01) of atosiban (P < 0.005). There was also a significant difference (P < 0.05) when comparing the 20 mg group (1.01) to the ewes treated with 5 and 10 mg of atosiban (1.02). Over the entire sampling period, mean log10 progesterone concentrations were lower (P < 0.001) in ewes treated with atosiban (1.00) compared to the control group (1.05). Among doses of atosiban, log10 concentrations of progesterone were lower (P < 0.0001) in ewes treated with 20 mg (0.99) atosiban than in ewes treated with 5 mg or 10 mg (1.01) atosiban. The overall effect of systemic treatment with atosiban in this study was to decrease mean log10 concentrations of progesterone relative to control ewes, which is in agreement with earlier findings using intraluteal infusion. The most effective dose of atosiban was 20 mg. In conclusion, systemic treatment with atosiban decreased concentrations of progesterone during the treatment phase of the experiment. Atosiban delivered in 20 mg maintained the lowest values in contrast to the control ewes and ewes treated with 5 or 10 mg of atosiban throughout the duration of the experiment.

▼ A study, conducted in two replicates, examined the effects of an artificial photoperiod on puberty in fall-born ewe lambs. Replicate I was initiated in December 2011 with prepubertal Dorset ewe lambs (n = 44). Replicate II was initiated beginning in December 2012 and included prepubertal Dorset, Suffolk x Dorset and Texel x Dorset ewe lambs (n = 52). All lambs were weighed at the initiation of each replicate and randomized to one of two treatments, control or treated, based on age, weight, breed and type of birth and rearing. Control ewe lambs were housed in a barn with exposure to natural photoperiod from December 16, 2011 until March 24, 2012 in replicate I and from December 17, 2012 until March 17, 2013 in replicate II. Treated ewe lambs were housed in a section of the same barn, but exposed to natural and supplemental light (~100 lux at lamb eye level) to produce an artificial photoperiod of 16 hours light and 8 hours dark for 14 weeks, from December 16, 2011 until March 24, 2012 in replicate I and from December 17, 2012 until March 25, 2013 in replicate II. Following completion of light treatment, each treated female received a silastic implant containing 20 mg of melatonin (Melovine), subcutaneously in the ear. Light intensity during the artificial lighting period for the treated group was measured, at random intervals, throughout the experiment and had an average value of ~100 lux, at ewe lamb eye level as measured by a Digital Light Meter (LX1010B). Growth of the lambs was monitored, as both weight and age are integral components of puberty. All ewe lambs were weighed at four time points during the study, including onset for each replicate, weaning, light termination and CIDR insertion. Ewe lambs were synchronized for estrus with the use of CIDR-G inserts, administered on May 18 of each year. On May 23 of each year CIDR implants were removed and intact fertile rams introduced. Rams were removed on June 19, 2012 or June 25, 2013 after allowing a breeding period of two opportunities for behavioral estrus. Pregnancy was determined by transrectal ultrasonography 25 days after removal of the rams. Progesterone was assayed, on all animals at four time points, using a radioimmunoassay. Plasma melatonin was assayed, in a subset of both treated and control females in replicate I prior to light termination, using an ELISA method. At light termination; treated females, in replicate I, weighed an average of 52.9 +/- 1.6 kg compared to 48.1 +/- 1.6 kg for control females (P < 0.05). Extended light photoperiod increased weight gain in Replicate I, but not in Replicate II. Overall, fall-born Dorset ewe lambs (56 to 57%) conceived their first spring with no effect of the artificial photoperiod/melatonin treatment. Suffolk- and Texel-sired lambs from Dorset ewes did not have the out-of-season breeding ability seen in the purebred Dorset ewe lambs, even with the artificial photoperiod/melatonin treatment; only 2 0f 14 (14%) of Suffolk-sired ewe lambs conceived.

▼ A study was conducted to investigate the effect of rigor development, at time of processing, on weight and length changes, proximate analysis, pH, K-value, color, and texture of rainbow trout (Oncorhynchus mykiss ) fillets. Texture of cooked fillets was characterized using two instrumental methods: Allo-kramer and Variable blade. Forty-five rainbow trout were harvested and immediately slaughtered using percussive stunning they were stored, following evisceration, at 4°C on ice. Fish were processed at 0, 24, and 48 h postharvest, and fillets were vacuumed packaged and stored for 2 days at 4°C. These storage treatments were applauded in the context of a randomized complete block design. Condition factor, whole body weight, head – on gutted (HOG) weight, length, percent butterfly fillet, HOG weight, and separable muscle were not affected (P > 0.05) by processing time. After cooking, dimensional changes were not different as a function of processing time. At 48 h postharvest, fillets were wider and longer (P>0.05), in value than the other groups. The 0-h, postharvest fillets were thicker (P<0.05) than those filleted at 24 and 48h, indicative of dimensional changes associated with muscle contraction in the absence of skeletal restraint.;At 0 h, fillet pH was (P.0.05) higher than at 24 or 48h; it is likely that all tissue glycogen had not been metabolized to lactic acid. Fillets moisture content and cook loss were (P > 0.05) lower at 0 h than at 24 and 48 h fillets, and higher cooked moisture was observed for fillets processed at 0 h. A higher fat content in raw (6.44 +/- 0.40) fillets and a lower fat content in cooked fillets (4.38 +/- 0.35) were measured for 0 h fillets compared to 24 and 48 h product. Ash and protein content was (P ≤ 0.05) higher at 0 h postharvest than at 24 and 48 h. A significant rapid decline in rigor angle from 0-24 h was observed, which is indicative of rigor resolution. Fillets L* value increased (P ≤ 0.05) as processing time, postharvest, increased; it was highest at 48 h processing. Meanwhile, 0 h fillets exhibited a (P ≤ 0.05) higher redness and yellowness value. The 0 h fillets had shorter sarcomere length than fillets produced at 24 or 48 h postharvest. ATP (Adenosine triphosphate) catabolizes and shear force were measured at 48 h postharvest for all processing treatments. Texture of trout fillet were affected (P ≤ 0.05) by time of processing, which might be due to the activity of myofibrillar proteolysis within the fillets' muscle. During rigor development, ATP concentration decreased as fillets went into rigor. Adenosine triphosphate (ATP) gradually decreased (P ≤ 0.05) with processing time. Adenosine diphoshate (ADP) and adenosine monophosphate (AMP) were not affected by processing time. Inosine monophosphate (IMP) and inosine (INO) increased (P ≤ 0.05) to 48 h postharvest. Hypoxanthine remained constant after 0 h postharvest. In conclusion, rainbow trout could be processed at 0 h postharvest without negatively affecting product quality. Advisors/Committee Members: P.

▼ Very few authors have studied the effect of the sire on the outcome of pregnancy in sheep beyond differentiation, development, spermatogenesis, fertilization and early embryo survival. A major limitation in direct selection for increased sire competence is that males need to be selected mainly on the performance of their female relatives and females do not express lambing traits until at least one or two years of age. This selection process can be accelerated by studying prenatal survival ability of individual ram's progeny.;The objective of the present study was to identify occurrence of late embryonic and fetal mortality in relation to individual sires. The data set included 980 ewes on 10 farms; each ewe pregnant to one of 67 rams of 12 breeds. Number of embryos or fetuses was determined by transrectal or transabdominal ultrasonography. Records of lambs born showed that potential litter size was underestimated in at least 166 of the ewes. Factors investigated for effects on numbers of lambs born were number of embryos at diagnosis (single or multiple), individual ram, breed of ram, month ewe was bred, breed of the ewe, age of the ewe, embryo type (purebred or crossbred), farm and interactions among these factors. The GLM procedure of SAS was used to examine the main effects and interactions of these factors on the pregnancy outcome. Individual rams that ewes were bred to had a significant effect on the number of lambs born from the pregnancy.;Individual rams sired from 0.70 lambs to 2.45 lambs born per pregnant ewe. In addition, litter size varied with the interaction of breed-type of ram and number of diagnosed embryos. Ewes diagnosed with twins were more often underestimated due to an unusually high number of triplet and quadruplet births. The number of lambs born increased linearly with the age of the ewe. The number of lambs born varied significantly (<0.05) with farm as well as with the farm by number of diagnosed embryos interaction.;Losses of embryos and fetuses sired by hair-type rams (42%) or black-faced rams (30%) were greater than for white-faced rams (20%) or dairy-type rams (21%). Fewer partial losses were observed among embryos and fetuses sired by white-faced rams, but complete losses were greater for the hair-type and white-faced rams. Hair-type ewes (46%) lost significantly more documented embryos or fetuses from the time of examination to birth than black-faced (27%), white-faced (20%), or dairy-type (25%) ewes. Surprisingly, purebred embryos had fewer documented deaths than crossbred embryos. Losses varied with farm and the farm by number of diagnosed embryos interaction (P<0.001), reflecting both expected flock differences and the variation in breed-type composition of the flocks.;In conclusion, the sire influenced the conceptus's ability to develop to term. Although, much of the paternal role is still a mystery, careful ram selection based upon previous records of pregnancy losses in ewes they were bred to may decrease embryonic and fetal wastage by improving conceptus competence genetically.… Advisors/Committee Members: E.
