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 …
