3、 challenges to Chinas pig industry.In order to quickly restore the production capacity of pigs,large number of tik-tak sows to fill the gap in breeding sows.n 回交二元母猪缺乏管理标准，如何确定回交二元母猪最佳的背膘值，是生产管理者需要面对的问题之一。As lack of management standards for tik-tak sows,how to determine the optimal backfat value for

4、 tik-tak sows is one of the issues that production managers facing currently.背景介绍INTRODUCTIONINTRODUCTIONn 分析回交二元母猪，在不同阶段背膘厚度与繁殖性能之间的关系，探讨生产中各阶段母猪最佳背膘厚度和整个妊娠阶段背膘厚度的最佳范围,为实际生产中的妊娠母猪精准管理和背膘控制提供参考依据 The relationship between backfat thickness and reproductive performance of tik-tak sows at different sta

5、ges is analyzed to explore the optimal backfat thickness of sows at each stage and the optimal range of backfat thickness throughout the gestation stage,and to provide a reference basis for accurate management and backfat control of gestating sows in actual productionn 由于背膘测量工作量相对较大，通过对同一母猪体况使用背膘卡尺、

6、眼观评分、背膘仪进行测量，并分析数据的相关性，研究体况评估是否能够代替背膘仪测量。Due to the relatively large workload of backfat measurement，the same sow body condition is measured by backfat calipers,5 score assessment and backfat meters to explore the correlation between these three methods and investigate whether body condition assessm
