摘要
本次实验选用体重为15kg左右的三元(大白×长白×杜洛克)杂种商品仔猪35头,随机分为三个处理,A饲料重复5次,B饲料重复5次,C饲料重复7次,每个重复2头猪(A饲料有一个重复为3头猪)。分别喂养A、B、C三种赖氨酸(含量分别为1.1%、1.05%、1.25%)配比的商品饲料。实验表明:A、B、C三种饲料在日增重和料肉比这两个生长性状之间差异显著,增重效果为C>A>B,料肉比大小为B>A>C,建议15kg左右阶段的仔猪的饲料赖氨酸需要量为1.25%。
35 hybrid piglets with weighed 15 kg were randomly divided into three groups. Feed A was fed 5 times, feed B was fed 5 times , feed C was fed seven times, each treatment including 2 piglets. Feed A, B, C with lysine content of 1. 1%, 1.05%, 1.25% were fed respectively. The experimental results showed that there is significant difference in daily gain and feed conversion ratio. C 〉 A 〉 B in daily gain, B 〉 A 〉 C in feed conversion ratio. It is recommended that piglets weighed 15 kg need lysine content of 1.25% in feed.
