Novel Dan-line replacement gilt estrus inducing mode

The invention provides a novel Dan-line replacement gilt estrus inducing mode. The novel Dan-line replacement gilt estrus inducing mode comprises the following steps: S1, breeding in S2, adjusting the initial estrus period; s3, precise feeding adjustment; s4, inducing estrus and mating. According to the novel estrus inducing mode for the Dan-line replacement gilts provided by the technical scheme, the estrus inducing starting time is adjusted to 140 days old, the Dan-line replacement gilts with excellent reproductive performance are better bred, the lifelong NPD accumulation of swinery is reduced, the use space of an animal house, the feed input and the labor input cost are reduced, and therefore the production benefit and the feeding management efficiency of a pig farm are improved. 本发明提供一种新型丹系后备母猪诱情方式，包括如下步骤：S1.育成期饲养；S2.初情期调整；S3.精确饲喂调节；S4.诱情配种。本技术方案提出的一种新型丹系后备母猪诱情方式，调整诱情启动时间至140日龄，更好的培育繁殖性能优异的丹系后备母猪，减少猪群终身NPD的蓄积，降低畜舍使用空间、饲料投入及人工投入成本，从而提高猪场的生产效益及饲养管理效率。
