非特异性卵黄抗体对雏鸡生长性能、免疫机能及微生物数量的影响
Effects of Nonspecific IgY on Growth Performance,Immune Function and Microbiota Number of Chicks
摘要
Abstract
This experiment was conducted to study the effects of dietary nonspecific IgY on growth performance,immune function and microbiota number of chicks,to provide the theory basis for practical application as feed additive in livestock and poultry.240 one-day-old Roman rooster hens with same batch of hatching and similar body weight were randomly divided into 2 groups (control group and experimental group),with 6 replicates in each group and 20 chicks in each replicate.Chicks in the control group were fed with a basal diet,and the others in the experimental group were fed the basal diet supplemented with 0.1% nonspecific IgY.The experiment lasted for 6 weeks.At the age of 6 weeks,2 chicks from each replicate were weighed and slaughtered,and the development of internal organs,immune index and microbiota number were determined.The results showed that:Comparing with the control group,the weight of chicks at the age of 1 and 5 weeks,the glandular stomach weight,spleen weight,serum IL-2 content,jejunal sIgA content and cecal Lactobacilli number in experimental group were significantly increased (P<0.05).In conclusion,dietary supplementation of nonspecific IgY could enhance growth performance,digestive organ development,immune function,and intestinal bacteria number.关键词
