摘  要：
选用120只1日龄艾拔益加(arbor acres,AA)肉鸡随机分为2组,每组6个重复,每重复10只。对照组饲喂基础日粮,实验组在基础日粮中添加750 mg/kg甜菜碱。结果表明,甜菜碱显著提高了肉鸡胸肌率和胸肌中粗蛋白含量(P<0.05),并显著提高胸肌p H24 h值,降低48 h滴水损失(P<0.05),但对肉色无显著影响(P>0.05);甜菜碱显著提高了胸肌中总超氧化物歧化酶活力和谷胱甘肽含量,降低了丙二醛含量(P<0.05)。结果提示,甜菜碱能有效提高胸肌率,且能提高胸肌肉中粗蛋白含量和胸肌p H值、增强胸肌系水力及胸肌的抗氧化功能。

摘  要：
A total of 120 one-day-old Arbor Acres broilers were randomly divided into 2 dietary treatment groups with 6 replicates of 10 broilers in each cage. The control broilers were fed a basal diet and those in the treatment group were fed a basal diet supplemented with 750 mg/kg betaine until 42 days of age. The results showed that betaine supplementation increased significantly(P < 0.05) breast muscle percentage and crude protein content. Betaine increased significantly(P < 0.05) p H24 h and decreased(P < 0.05) drip loss at 48 h postmortem, but had no effect on meat color. Moreover, betaine increased significantly(P < 0.05) superoxide dismutase activity and glutathione content, and decrease(P < 0.05) malondialdehyde content in breast muscle. These results suggested that betaine was effective in improving breast muscle percentage and the crude protein content in breast muscle. Moreover, betaine has positive effect on p H, water-holding capacity and antioxidant function in breast muscle of broilers.
