| 摘 要： | 将40只初生体质量相近的无角陶赛特与小尾寒羊F1代羔羊随即分成A、B、C、D 4组。A、B、C组羔羊在10~15日龄同时断奶,分别喂以A、B和C 3种代乳料,D组羔羊则继续由母羊哺乳饲喂。结果表明,在整个试验阶段(10~55日龄),A组平均日增质量(0.224±0.03)kg,极显著高于B组、C组和D组(P<0.01);B组和C组差异不显著(P>0.05),两组极显著高于D组(P<0.01);试验组和对照组体高、体长和胸围基本一致。3个试验组羔羊粪中干物质含量均高于20%,因此,各组羔羊均处于正常生长范围。

| Abstract: | 10 hybrid F1 lambs of Poll Dorset×Small Tailed Han sheep with similar body weight were allocated to 4 groups,and the lambs of group A,B and C were weaned at the age of 10-15 days,then fed on milk replacer for group A,B and C,respectively,but the group D fed by their mothers.The results showed that the average daily gain of group A was(0.224±0.03)kg,dominantly higher than the others(P<0.01),and there was no obvious difference between group B and group C(P>0.05)but both were significantly higher than that of group D(P<0.01).The body sizes of 4 groups were almost the same.The fecal dry matter content in group A,B and C was above 20%.It was confirmed that lambs from the 3 groups grew normally. |
