摘要
为了研究光照与药物控制同期发情对母兔窝产仔数的影响,试验选用150日龄体质相近的父母代伊拉母兔80只,随机分为2组,每组40只。试验组连续7 d人工光照后人工授精繁殖;对照组自然光照,注射孕马血清促性腺激素(PMSG)后人工授精繁殖。结果表明:经168 d,2种方法对母兔窝产仔数影响不大,经t检验,平均窝产仔数和平均窝产活仔数差异不显著(P>0.05),说明光照控制母兔同期发情技术完全能应用到商品肉兔的繁殖生产中。
To study the difference between the effects of lighting and drug to control estrus synchronization on the litter size of female rabbits, 80 Ira female rabbits of parent generation with the age of 150 days and the similar constitution, were randomly divided into two groups of 40 rabbits each. The rabbits in the experimental group were artificially inseminated for reproduction after using continuous artificial lighting for 7days. The rabbits in the control group with natural lighting were artificially inseminated for reproduction after injecting pregnant mare serum gonadotropin （PMSG）. The results showed that there waS no big difference between the effects of the two methods on the litter size of female rabbits after a 168 d, and there was no significant difference （P 〉0.05） in the average litter size and live litter size by t - test. The results indicate that the tech- nology of lighting to control estrus synchronization of female rabbits can be completely applied to the breeding production of commercial rabbits.
