This study investigated the effects of adverse environmental conditions on the muscle properties of poultry meat. Analyses of water-holding properties of chicken meat showed that breast meat was more sensitive to antemortem temperature than leg meat. Meat from chickens exposed t…
Three experiments were conducted to address the validity of an inherent fatness hypothesis in chickens and turkeys. In chicken experiments, one third of chicks were fattened with a low protein: energy ratio diet (12% CP; LP). The second and third groups, were made lean by either…
A relatively new instrument known as a Sperm Quality Analyzer ® (SQA) offers a rapid assessment of sperm quality and quantity by providing a sperm quality index (SQI). The SQA measures the intensity of sperm activity and motile concentration by determining the number and amplitu…
The present study evaluated effects of in vitro treatment of gossypol (GP) on testosterone (T) secretion in rat, dog, boar, and bull testicular interstitial cells as well as progesterone and estradiol secretion in porcine granulosa cells. In addition, changes in progesterone sec…
Donkeys survive under conditions inhospitable to horses and cattle. Energy intake and expenditure was studied using 12 donkeys at Cornell (4 male, 2 female, body weight (BW) 200 ± 18 kg) and at the Institute for Crops Research in the Semi-Arid Tropics in southern Niger (6 female…
The Acehnese are an ethnic group living in Aceh Province of far western Indonesia, who consider themselves ethnically distinct and righteous Muslims. They are very active in raising livestock, principally cattle, buffalo and goats, on common lands found throughout the province. …
Three experiments were conducted to evaluate the influence of phosphorus sources and level, Ca:P ratio, fluorine and heat stress on performance of turkey poults and broiler chicks. Two additional experiments were conducted primarily to measure the bioavailability of fluorine in …
Ingestive and ruminative chewing, meal and dorsal rumen contractions were measured in yearling beef steers offered forage diets based on either Coastal bermudagrass (Cynodon dactylon (L.) Pers) or sorghum X sudan (Sorghum bicolor (L.) Moensch) hays. Diets were supplemented with …
Thiaminase-I was purified from the growth medium of Clostridium sporogenes by salt precipitation, dialysis and/or column chromatography. The modified thiaminase radioassay used in this study was based on extracting the ('14)C thiazole, released by thiaminase action on a ('14)C(,…
In Exp. I the effect of mineral supplementation on reproductive performance of cows grazing native range at two locations (McCulloch--supplemented prior breeding season and Edwards--supplemented throughout breeding season) was monitored by tissue (serum and liver) parameters, bo…
This dissertation uses agent-based computer simulation to examine general processes that generate patterns of social organization among nomadic pastoral populations in Inner Asia. Of particular interest are processes related to the formation of nomadic states and empires, such a…
Developmental patterns of tissue ornithine decarboxylase (OCD) activity and nucleic acid concentrations were evaluated in breast and leg muscle in a randombred control population (RBC2), a line selected for increased 16-week body weight (F), and a commercial sire line selected f…
The main objective of this research was to assess the nutritional status of sheep and goats grazing two rangeland types in Baluchistan, Pakistan. These types were Artemisia maritima/Haloxylon griffithii association represented by the Zarchi Field Station and Cymbopogon shoenanth…
Two experiments were conducted with beef steers to determine the potential of dried silvacel apple pomace (DSAP) as roughage sources in both maintenance and growing finishing diets. The first experiment was a replicated Latin square design with eight long yearling steers. The di…
Young turkeys weighing 13.6 kg were electrically stunned for 5 seconds with a current of 250 mA. Samples of the Biceps femoris and Pectoralis major were taken at 0, 4, 8, and 24 hours postmortem. No differences in postmortem muscle structure between stunned and nonstunned muscle…
This study was designed to determine whether propranolol or digitalis would modify the congestive cardiomyopathy in turkey poults fed furazolidone. Even though all birds fed furazolidone whether given digoxin or not developed cardiomyopathy, none of the birds fed furazolidone pl…
Two random complete block experiments were conducted to determine the silage yield and quality of forage sorghum cultivars. In Experiment 1, 80 cultivars were used; in Experiment 2, 60 of the 80 were compared. Year by hybrid interaction was significant (P =.05). Significant diff…
