摘要
选取３日龄艾维菌健康雏鸡４００只，随机分成４组。Ⅰ组为对照组，Ⅱ组添加维生素Ｃ，Ⅲ组添加粗酶制剂，Ⅳ组添加粗酶制剂与维生素Ｃ，饲喂３５ｄ。结果表明：１０日龄时，Ⅱ，Ⅲ，Ⅳ组体增重显著高于Ⅰ组；１７日龄和３５日龄时，各组间体增重差异不显著。Ⅰ，Ⅱ，Ⅲ，Ⅳ组的３５日龄全程料肉质量比分别为２０９８，１９９５，１９９７，１９０４。说明在肉鸡生长早期（１４ｄ前）添加粗酶制剂和维生素Ｃ能显著促进生长，但在中后期促生长作用不显著。饲料中添加粗酶制剂与维生素Ｃ还可降低全程料肉质量比。
three day old chicken were randomly divided into four groups, contrast group was group Ⅰ, group Ⅱ,Ⅲ,Ⅳ were respectively added vitamin C, coarse enzyme preparation, coarse enzyme preparation and vitamin C. The results showed that the increasing weights of group Ⅱ, Ⅲ, Ⅳ was higher than group Ⅰ at the tenth day; In the period of experiment the mass ratio of forage and meat of each group (Ⅰ, Ⅱ, Ⅲ, Ⅳ) was 2.098, 1.995, 1.997, 1.904, and that added coarse enzyme preparation and vitamin C could promote broiler chicken's growing in two weeks after hatching, but no significant effects after two weeks. The results also showed that coarse enzyme preparation and vitamin C added to the forage could decrease the mass ratio of forage and meat.
