家庭牧场绵羊非繁殖季节诱导发情试验

【目的】在放牧条件下,对处于非繁殖季节的473只家庭牧场的细毛羊进行同期发情处理,以期提高非繁殖季节绵羊繁殖率,从而增加农牧民的收入,为家庭牧场的牧户提供技术指导。【方法】采用阴道栓埋植的方法,诱导细毛羊发情。【结果】在家庭牧场中的细毛羊且在放牧条件下能够在非繁殖季节发情,三批试验羊的情期受胎率分别为75.5%、88.64%、80%。【结论】在非繁殖季节细毛羊同期发情的成功为绵羊实现高效生产奠定基础;增加牧户规模化养殖的信心。

Study on Estrus Induction of Fine - wool Sheep in Non - breeding Season

Objective]The purpose of this research was to enhance reproduction rate of fine - wool sheep in non - breeding season by studying the estrus synchronization of the fine - wool sheep under grazing condition,thereby increasing the income of herdsmen,and providing technical guidance for the family ranch of the herders.Method]Vaginal suppository was used to be implanted to induce fine -wool sheep estrous.The results show that fine - wool sheep can estrus in non - breeding season.Result]The pregnancy rate of the three times test sheep is 75.5%,88.64%,80%,respectively.Conclusion]The success of estrus synchronization in non - breeding season of fine - wool sheep made the efficient production of sheep and increased the confidence of the herdsman to large - scale breeding.
