复方中草药饲料添加剂替代抗生素对肉仔鸡生产性能的影响

Effect of Compound Chinese Medicinal Herb Additive on Broiler Growth Performance

采用随机单位组设计,将1 000羽白羽肉仔鸡随机分为五组。Ⅰ组(基础日粮+黄霉素75mg/kg和洛克沙胂45.75mg/kg),Ⅱ组(基础日粮+中草药0.3%水平),Ⅲ组(基础日粮+中草药0.4%水平),Ⅳ组(基础日粮+中草药0.3%水平+甜菜碱),Ⅴ组(基础日粮)。结果表明:中草药添加剂0.3%水平组(Ⅱ、Ⅳ组)与抗生素组、对照组的活重、料重比、日增重、采食量的差异极显著(P<0.01),该中草药组方的0.3%水平为最适添加量。

1000 broiler chickens were randomly divided into five groups with unit group design.Ⅰgroup（basal diets＋ 75mg/kg flavomycin＋ 45.75mg/kg roxarsone）;Ⅱ group（basal diets＋0.3% Chinese medicinal herb additive）;Ⅲ group（basal diets＋ 0.4% Chinese medicinal herb additive;Ⅳ group（basal diets＋0.3% Chinese medicinal herb additive＋ lycine）;Ⅴ group（basal diets）.The results showed that live weight,feed gain ratio and feed intake of the group with 0.3% Chinese medicinal herb additive（Ⅱ group and Ⅳ group） were significantly different with antibitics group and control group（P〈0.01）,the optimal amount of Chinese medicinal herb additive is 0.3%.
