益生素YS对三黄鸡生长性能和免疫功能的影响

选用1日龄三黄鸡100只，分为五组，每组设两个重复，各10只雏鸡。对照组饲喂基础日粮；抗生素组饲喂添加0.2%恩诺沙星的基础日粮；试验组饲喂添加有益生素YS的基础日粮，添加量分别为0.5%、1.0%、1.5%；试验进行8周。试验结果表明，益生素YS有提高三黄鸡平均日增重和显著降低料重比的作用，以1.0%益生素YS添加组的平均日增重为最高；比对照组提高22.39%；益生素YS可以使三黄鸡血清中的钙、磷、总蛋白、白蛋白、球蛋白、溶菌酶、IgG、IgA的含量增加，并能提高淋巴细胞转化率及胸腺、脾脏和法氏囊指数；益生素YS在三黄鸡日粮中的适宜添加量为1.0%～1.5%。

Effect of Probiotics YS on the Growth Performance and Immune Function in Three Buff Chickens

In the paper, effect of Lactic acid Bacillus SC and Lactobacillus rhamnosus LT22 coculture (probiotics YS) on the growth performance and immune function in three buff chickens was studied.100 one-day-old three buff chickens for an experimental period of 8 weeks, were randomly allotted into 5 groups each with two replicates, each replicate was ten chickens. The control group was provided with the basal diet, the antibiotic group was fed with basal diet supplemented with enrofloxacin at the level of 0.2%, the...
