摘要：

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%。

Abstract:

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 other groups were fed basal diet supplemented with probiotics YS at the level of 0.5%,1.0%,1.5% respectively. The results showed that probiotics YS could increase average daily gain and markedly reduce ratio of feedingstuff and gain weight; the maximum of average daily gain was probiotics YS at the level of 1.5% , was more 22.39% than control group; to three buff chickens, probiotics YS could increase the content of calcium, phosphorus, total protein, albumin, globulin, lysozyme, IgG, IgA in serum, and convert ratio of lymphocyte, and idexes of spleen, thymus, bursa; the suitable additive amount of probiotics YS in the basal diet of three buff chickens was 1.0%～1.5%.
