| 摘 要： | 试验采用完全随机试验设计,将1日龄的罗斯308肉鸡360只分成6组,每组3个重复,每个重复20只鸡,研究蛋氨酸锌(ZnMet)对肉鸡平均日增重(ADG)、平均日采食量(ADFI)和料重比(F/G)以及免疫器官指数和ND抗体效价的影响。日粮处理组为在不添加锌的玉米-豆粕型基础饲粮基础上分别添加20、40、60、80和100mg/kg水平的蛋氨酸锌(以锌计),结果表明,饲粮中添加蛋氨酸锌能提高肉鸡的平均日增重,改善料重比和免疫功能,60～80mg/kg为适宜添加量。

| Abstract: | The experiments used complete random experiment design.360 Luo Si broilers at 1-day age were divided into 6 groups with three depiicates of 20 broilers.The effect of ZnMet on broiler's average daily gain,average daily feed intake,feed gain ratio,immune organ index and ND antiboby titer were studied.Corn-soybean meal basic diet(with on Zn) supplemented with 20,40,60,80 and 100 mg/kg Zn-Met were as diet treatment groups.The results showed that diet containing ZnMet could increase broil-er's average daily gain... |
