二色胡枝子提取物对肉仔鸡生产性能及抗氧化指标的影响

探讨日粮中添加二色胡枝子提取物(Extractive of Lespedeza bicolor,LBE)对肉仔鸡生产性能及抗氧化作用的影响。试验选用500只健康1日龄商品代艾维茵肉仔鸡随机分为10组,每组5个重复,试验期42d。对照组(CK)饲喂基础日粮,试验1～3组饲喂基础日粮加二色胡枝子粗提物90,100和110mg/kg;试验4～6组饲喂基础日粮加二色胡枝子乙酸乙酯萃取物60,70和80mg/kg;试验7～9组饲喂基础日粮加二色胡枝子正丁醇萃取物60,70和80mg/kg。试验结果表明:日粮中添加二色胡枝子乙酸乙酯萃取物、正丁醇萃取物对肉仔鸡生产性能有促进作用,可提高肉仔鸡的抗氧化功能。

Effects of extractive of Lespedeza bicolor on growth performance and antioxidant indices in the broiler

The study was conducted to investigate effects of the extractive of Lespedeza bicolor (LBE) on growth performance and antioxidant indices in the broiler. A total of 500 healthy Avian broilers of 1-day-old were randomly assigned to ten treatments with five replicates. The experimental period prolonged for 42 days. The control group (CK) was fed basal diet, group 1 to 3 fed basal diet supplemented with 90, 100 and 110 mg/kg of Lespedeza Bicolor crude extract, group 4 to 6 fed basal diet supplemented with 60, 70 and 80 mg/kg of ethyl acetate extractive, and group 7 to9 fed basal diet supplemented with 60, 70 and 80 mg/kg of n-butanol extractive. The results showed that supplemented ethyl acetate extractive and n-butanol extractive of LBF can significant elevate performance of broilers and elevate antioxidant functions in the broiler.
