伊拉配套系商品代母兔与父母代种兔系列后代生长性能对比试验

Comparative Study on the Grouth Performance the Commercial Surrogate Male Rabbit and the Parent Surrogate Rabbit of IRA Rabbit

在同一环境下开展伊拉配套系父母代种兔与伊拉商品代兔中选留母兔的性能测定工作,随机选取伊拉配套系父母代种兔和商品代母兔各65只,开展连续3个胎次的繁殖性能和生产性能测定。试验结果显示,除21日龄平均窝重存在显著差异(父母代种母兔高于商品代母兔)以外,其他繁殖性能各项指标无显著差异。

In the same environment,the performance of the female rabbits selected from the parents and the commercial rabbits were determined.The reproductive performance and production performance of the three consecutive parity were measured.The experimental results showed that there was no significant difference in reproductive performance except for 21 days old average litter weight(parental female rabbit was higher than commercial female rabbit),and there was no significant difference in reproductive performance.
