摘要
随机选择天府黑兔和新西兰兔各60只作为试验动物,对两个品种的家兔早期生长性能和饲料转化率进行比较研究。结果表明:天府黑兔和新西兰兔在30～75日龄阶段,其生长速度呈上升趋势,75日龄后生长速度呈下降趋势;天府黑兔生长强度比新西兰兔大,30～90日龄平均日增重天府黑兔35 5g,新西兰兔27 5g,差异极显著(P<0 01);饲料报酬和成活率天府黑兔高于新西兰兔,但差异不显著(P>0 05)。
60 Tianfu Black Rabbits and 60 New Zealand Rabbits were randomly selected to compare their growth rate and feed conversion efficiency. The results show that both breeds have a rapid growth during 30～75 days, but growth rate declines after 75 days of age; Growth intensity of Tianfu Black Rabbit is higher than New Zealand Rabbit, daily gain of Tianfu Black Rabbit is 355?g during 30～90 days, while New Zealand Rabbit is 275?g (P＜005); Feed conversion efficiency and surviving rate of Tianfu Black Rabbit are higher than that of New Zealand Rabbit, but differences are not significant (P＜005).
