摘要/Abstract

摘要： 为研究湘沙猪配套系母系母本XS3 系和父母代母猪的繁殖性能，试验选择了湘沙猪配套系选育场2018 年至2023年期间部分繁殖性能数据，经分析发现：⑴在纯繁模式下，XS3 系母猪在第1～7 胎次中，以第4～7 胎次的繁殖性能最好；⑵在杂交模式下，XS3 系母猪与新美系长白公猪或新美系大白公猪配种，其繁殖性能明显优于与新美系巴克夏公猪配种；⑶湘沙猪配套系父母代母猪在第1～4 胎次，以第4 胎次的繁殖性能最好。综上，胎次对湘沙猪配套系XS3 系和父母代母猪的繁殖性能有显著影响，与不同品种公猪配种，对湘沙猪配套系XS3 系母猪的繁殖性能也有显著影响，这为湘沙猪配套系的持续选育提供数据依据。

Abstract: To investigate the reproductive performance of XS3 line sows and the parental generation sows of Xiangsha pig commercial lines, some reproductive performance data of Xiangsha pig commercial lines breeding farm from 2018 to 2023 were selected. After analysis, it was found that: ⑴ Under the pure breeding model, among the XS3 line sows in parity 1 to 7, the reproductive performance was optimal in parity 4 to 7. ⑵ Under the hybrid model, when the mating boars were Yorkshire or Landrace pigs, the reproductive performance of XS3 line sows were significantly better than when the mating boars were Berkshire pigs. ⑶ Among the parental generation sows of Xiangsha pig commercial lines in parity 1 to 4, the reproductive performance was optimal in the 4th parity. In summary, parity had a significant impact on the reproductive performance of the XS3 line sows and the parental generation sows of Xiangsha pig commercial lines, and different breeds of boars also had a significant impact on the reproductive performance of the XS3 line sows. It provided data basis for the continuous breeding of Xiangsha pig breeding lines.
