烯丙孕素在猪场批次化生产中的应用效果

The Effect of Altrenogest on Batch Management in Pig Farm

自2018年非洲猪瘟疫情给我国养猪业造成巨大损失,经过1年多的摸索和验证,国内养猪集团公司总结出了多点饲养、猪场硬件“铁桶计划”、三级生物安全支持体系等技术将非洲猪瘟病毒拒之场外,因此猪场采用批次化生产方式,一次断奶就让肥育场放满猪苗,饲养150~180 d后全部出栏,真正做到以肥育场为单位的全进全出,成为多点饲养防控非洲猪瘟的关键。目前,烯丙孕素是批次化生产的关键外源激素,主要应用于后备母猪和乏情经产母猪的同期发情[1]。此文统计2019年11月至2021年8月数据,烯丙孕素在后备母猪批次化生产中的应用效果表明,烯丙孕素+查情的简式同期发情配种模式在养猪生产中具有推广意义。

The epidemic of African Swine Fever in 2018 led to huge losses of Chinese pig industry.After more than one year of exploration and practice,some large-scale group company have summarized the multi-point feeding,improving biosecurity system,such as"iron bucket plan",three levels biosecurity cycle,those technology and methods keep the African Swine Fever virus out of the field.Therefore,the pig farm adopts batch management.The finish building will be filled with weaned piglets,and the piglet will be raised 150-180 days in the same building.All-in,all-out and multi-point feeding has become the key points to prevent and control the African swine fever.At present,altrenogest is the key exogenous hormone for batch management,and it is mainly used in the estrus of gilts and anestrus sows for synchronous oestrus[1].This article counts the data from November 2019 to August 2021.The application effect of altrenogest in batch management of gilts shows that altrenogest+synchronous oestrus breeding and simple checking-model could be popularized in pig production.
