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)。

Abstract: 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 35.5 g during 30~90 days, while New Zealand Rabbit is 27.5 g(P<0.05); Feed conversion efficiency and surviving rate of Tianfu Black Rabbit are higher than that of New Zealand Rabbit, but differences are not significant(P<0.05).

Key words: GROWTH INTENSITY, FEED CONVERSION EFFICIENCY, SURVIVING RATE, TIANFU BLACK RABBIT, NEW ZEALAND RABBIT
