定制化饲料对从岭藏鸡生长性能、抗氧化能力、免疫功能及盲肠菌群的影响
Effects of Customized Feed on Growth Performance,Antioxidant Capacity,Immune Function and Cecal Microbiota of Congling-Tibetan Chickens
摘要
Abstract
The study aimed to investigate the effects of customized feed on the growth performance,antioxi-dant capacity,immune function and cecal microbiota of Congling-Tibetan chickens.One thousand two hundred newly hatched chicks,were randomly assigned into two experimental treatments,with six repli-cates in each treatment and 100 chickens in each replicate.The control group was fed with ordinary broiler feed together with part of unprocessed grain according to the local breeding pattern in Zhouqu,while the testing group was fed with customized complete feed on the basis of the growth law of Congling-Tibetan chicks.The feeding experiment lasted for 60 d.The differences of growth performance,feed con-version and immune function between the two groups were observed and analyzed.The results showed that the customized feed significantly increased the average body gain from 1 to 28 and average feed intake from 29 to 60(P<0.01).The results of 16S rDNA sequencing for microbiota in the cecum of Congling-Tibetan chickens showed that the abundances of Rumen coccus and Barnesia spp.were up-regulated,and that of Faecalibacte-rium spp.was down-regulated.In summary,the customized feed improved the growth performance of Congling-Tibetan chickens,improved the serum bio-chemical indexes,enhanced the antioxidant capacity of serum,jejunal mucosa and liver,and the immune function of serum and jejunal mucosa,reduced intestinal inflammatory response,and optimized the struc-ture of cecal microbial flora.关键词
