中国白兔生长发育特性的研究

A Study of Growth Traits in Chinese White Rabbit

本研究对初生、２１、２８、３０、６０、９０、１２０、１５０、１８０日龄和１２月龄等不同阶段中国白兔的增重、成活率和繁殖性能进行测定，结果如下：窝均产仔８．０７只，初生产４９．１６克，２８日龄断奶产２８５．９６克，断奶成活率９４．９２％；９０日龄产９７１．１０克，成活率８２．２２％；１８０日龄产１７３２．７８克，成活率９１．２２％；成年体重２２７３．３３克。结果显示：中国白兔成年体重小，生长速度较慢，但繁殖能力强。

Measurements of Livability,reproductive performence and Liveweight gain at birth,21,28,30,60,90,120,150,180 days and yearling wt.of Chinese White Babbit were collected,Some results are as follows:number bornalive 8.07,birth wt.49.16g,weaning wt.at 28 days 285.96g and weaning Livability 94.92%,body wt.at 90 days 971.10g and Livability 82.22%,body wt.at 180 days 1732.78g and Livability 91.22%,and mature wt.2273.33g.It showed that Chinese White Rabbit have traits of Light body size and lower growth rate,but be possess of high-fecundity and high-Livability.
