茶多酚对高酒糟日粮肉鸡生产性能和抗氧化特性的影响
Effects of dietary tea polyphenols on growth performance and antioxidant activity in broilers fed with high levels of DDGS diets
摘要
Abstract
This study was to evaluate the effect of dietary tea polyphenols ( TP) on growth performance and antioxidant performance in broilers. A total of 400 broilers at 21- day- old were assigned to 5 treatments with 4 replicates of 20 birds. Positive control was corn-soybean meal diet, negative control was corn-soybean-DDGS meal diet (15% DDGS) and treatments were supplemented with 100, 300 and 500 mg/ kg TP, respectively. The results showed that compared to positive control, the addition of 15% DDGS had no significant influence on growth performance of broilers, while GSH-Px level decreased by 8. 31% ( P>0. 05 ) ; T-AOC levels of thigh and breast meat decreased slightly ( P >0. 05 ) ; TP supplementation improved blood T-AOC, GSH-Px activity ( P<0. 05 ) , but there were no significant differences among different TP levels. More than 300 mg/kg TP could significantly decrease MDA of breast and thigh meat ( P>0. 05 ) and improve T-AOC levels. The results of current research suggested that dietary TP supplementation could improve antioxidant activity in body and meat of broilers fed with high levels of DDGS diets.关键词
