Effects of tea polyphenols and saponin on growth performance, intestinal microflora and antioxidant function of broilers with coccidian challenge
摘要
Abstract
This study was to investigate the effects of tea polyphenols and saponin on growth performance,intestinal microflora and antioxidant function of broilers with coccidian challenge.675 one-day-old yellow feather broilers,which confirmation no coccidian in stool at 14-day-old,were randomly assigned to 9 treatments with 5 replicates per group and 15 chickens per replicate,and at 21-day-old,all chickens were treated with coccidian challenge.The test ended on 42-dayold.The test control group was fed the basal diet,the treatments supplementation of 250,350 mg · kg-1 tea polyphenols (TP),100,200,300 mg · kg-1 tea saponin (TS),350 mg · kg-1 TP+150 mg · kg 1 TS,250 mg · kg-1 TP+150 mg · kg-1 TS on the basis of the basal diet,and the antibiotic control group.The results showed that compared with the control group,supplementation of 350 mg · kg-1 TP,300 mg · kg 1 TS and 250 mg · kg-1 TP+150 mg · kg-1 TS significantly improved performance of broilers,decreased the number of E.coli and increased the number of Lactobacillus in cecum of broilers (P ＜ 0.05);And there were no significant difference with the group supplementation of 200 mg · kg 1 Narasin.Supplementation of 250 mg · kg-1 TP+1S0 mg · kg 1 TS also significantly increased serum and duodenum T-AOC,SOD,CAT and decreased MDA of broilers (P＜0.05).Overall,under the conditions of this trial,a certain concentration level tea polyphenols and saponin increased the growth performance and antioxidant properties,improved the cecum microbial structure of broilers with coccidian challenge.In comparison,250 mg · kg-1 TP+150 mg · kg-1 TS was better.关键词
