舍温对獭兔繁殖性能的影响

Eeffects of House Temperature on Reproductive Performance of Rex Rabbit

选出体重、日龄、胎次相近的法系白色发情母獭兔75只,随机分成5个处理组,分别在人为控制舍温(Ⅰ组:1~15℃;Ⅱ组:8~20℃;Ⅲ组:12~25℃;Ⅳ组:16~28℃;Ⅴ组:19~32℃)的温度下交配妊娠,测定其繁殖力。结果表明:Ⅳ组母兔的产仔数显著高于Ⅰ组、Ⅱ组、Ⅴ组,产活仔数显著高于其他4组(P【0.05),仔兔断奶个体重显著高于Ⅰ组,仔兔断奶日增重显著高于Ⅰ组;Ⅴ组仔兔断奶成活率最高,显著高于Ⅰ组、Ⅳ组(P【0.05),仔兔断奶个体重、断奶日增重均显著高于其他组。

75 oestrous white rex rabbits were selected with the similar body weight,age and birth,randomly divided into 5 groups,mating and feeding in the artificial house temperature respectively(Group I:1 ~15℃;Group II: 8~20℃;Group III:12~25℃;Group IV:16~28℃;Group V:19~32℃),detected the reproductive capacity.The results indicated that the litter size of group IV was significantly higher than the group I,II,V,the number of live littermate significantly higher than the other 4 groups(P<0.05),the weaned individual body weight signifi-cantly higher than group I;The weaned survival rate of group V was significantly higher than group I,IV(P<0.05),the weaning individual weight and weaning daily gain weight was significantly higher than the other groups.
