Dietary Supplementation Of Choline And Betaine In Heat-Stressed Broilers, Kouassi Remi Kpodo
Dietary Supplementation Of Choline And Betaine In Heat-Stressed Broilers, Kouassi Remi Kpodo
Masters Theses
A study was conducted to determine the effects of supplemental choline (CHO) and betaine (BET) on broiler performance, carcass characteristics, corticosterone levels, immune organ weights, intestinal morphology and choline metabolites under thermoneutral (TN: 23.9oC) and heat stress (HS: 28-36oC) conditions. Eight hundred day-old chicks (400 per temperature treatment) were assigned in groups of 10 to each of five dietary treatments: 1 (CON) the basal diet; 2 (CHO500), basal diet plus 500 ppm methyl equivalents added CHO; 3 (CHO1000), basal diet plus 1000 ppm methyl equivalents added CHO; 4 (BET500), basal diet plus 500 ppm methyl equivalents …
Manipulating Adipose Tissue Fatty Acid Oxidation To Reduce Fatness In Broiler Chickens, Tania Emmanuelle Torchon
Manipulating Adipose Tissue Fatty Acid Oxidation To Reduce Fatness In Broiler Chickens, Tania Emmanuelle Torchon
Masters Theses
Compared to rodents, broiler chickens, those reared for meat, are an attractive model for studies of adipose biology, and obesity development in children. The broiler chicken lacks the gene for uncoupling protein 1, the hallmark for brown adipose tissue making them a useful model to study lipid metabolism in white adipocytes. Two studies were performed to investigate if white adipose tissue had the metabolic ability for fatty acid oxidation (FAO), and to investigate the effects of dietary fatty acids on abdominal fat development of young broiler chickens as a model for childhood obesity. In study one, chickens were fasted for …
Development And Evaluation Of Novel Vaccination Strategies For Campylobacter Control In Poultry, Xiang Liu
Development And Evaluation Of Novel Vaccination Strategies For Campylobacter Control In Poultry, Xiang Liu
Masters Theses
Chicken is the primary natural host of Campylobacter, the leading bacterial cause of human enteritis in the US and other developed countries. Thus, mitigation of Campylobacter in chicken using innovative approaches, such as vaccination, will have a significant impact on food safety and public health. Our previous studies have demonstrated that the two outer membrane proteins, CmeC (the essential component of the CmeABC multi-drug efflux pump) and CfrA (a ferric enterobactin receptor), are feasible candidates for immune intervention against Campylobacter. DNA vaccine has appeared to offer various advantages for poultry, particularly when combined with in ovo vaccination. Chitosan-encapsulated …
