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 Lipolysis To Reduce Fatness And Improve Carcass Composition In Commercial Broilers, Rodney Barnett Ray
Masters Theses
Betaine has been studied as an osmolyte and methyl group donor for many species. Recent studies have found that betaine is able to increase muscle mass and reduce adiposity in meat type broilers birds. In experiment one, eight-hundred Cobb 500 broiler chicks were supplemented with betaine at 0.6 g/kg and 1.2g/kg. Birds had access to feed and water for ad libitum consumption for forty-two, forty-four, and forty-nine days. Birds and feed were weighed weekly. Carcass parameters (dress weight, breast percentage, and leg percentage) were taken at slaughter on days forty- two and forty-nine. Blood was taken at day forty-four to …
