摘　　要：羊属于季节性发情动物,发情时间主要集中在每年5—10月。在品种改良中,如果沿用自然交配生产模式,会使整体的配种周期和产羔周期大大延长,极大影响繁殖母样的利用效率和养殖场的经济效益。在非繁殖季节,通过推广应用诱导发情技术,可实现繁殖母羊集中发行,缩短繁殖周期,提高肉羊的产高率。通过集中发情集中配种,集中生产,有利于实现集约化规模化管理,提高养殖场的整体繁殖效率。为进一步验证肉羊反季节诱导发行技术的配种效果,从2018年6月到2019年6月,连续2年在山东省平阴县的一个良种繁殖场中开展非季节繁殖试验,对更好地推动肉羊品种改良,提升养殖效益有一定帮助。Sheep belong to seasonal estrus,the estrus time is mainly concentrated in 5~10 months every year.If the natural mating production mode is used,the breeding cycle and lambing cycle will be greatly prolonged,which will greatly affect the utilization efficiency of breeding mother and the economic benefit of the farm.In the non-breeding season,through popularizing and applying estrus induction technology,we can realize the centralized issue of breeding ewes,shorten the breeding cycle,and improve the yield and high rate of mutton sheep.Through centralized oestrus centralized breeding,centralized production,is conducive to the realization of intensive scale management,improve the overall breeding efficiency of the farm.In order to further verify the breeding effect of out-of-season inducing and issuing techniques of mutton sheep,the off-season breeding experiments were carried out in a fine breed breeding farm in Pingyin county of Shandong province for two consecutive years from June 2018 to June 2019,it is helpful to improve the breed of mutton sheep and raise the benefit of breeding.
