摘　　要：为研究母猪品种和体况对其繁殖性能的影响,对杜洛克、长白、大约克和长大、大长母猪的繁殖期体况变化和窝产仔数进行了统计分析,同时对母猪体况和繁殖性能进行了相关分析。结果表明,母猪品种显著影响其繁殖性能,长白和大约克母猪的总产仔数、21日龄仔猪数、出生窝重、21日龄窝重均显著高于杜洛克母猪,其中总产仔数、21日龄仔猪数分别多0.96头和1.98头（P〈0.05）,出生窝重、21日龄窝重增加7.19%和25.37%（P〈0.05）,而与长大和大长二元母猪间差异不显著（P〉0.05）。母猪繁殖期背膘厚均显著影响母猪的繁殖性能,长白和大约克母猪配种、孕30d、分娩和21日龄仔猪断奶背膘厚均显著高于杜洛克母猪,提高6.63%-12.31%（P〈0.05）,但与长大和大长二元母猪4个节点背膘厚差异不显著（P〉0.05）。母猪妊娠期和哺乳期背膘厚与总产仔数、产活仔数、出生窝重、21日龄窝重等繁殖性状均呈极显著相关（P〈0.01）。由此可见,母猪品种与其繁殖期体况变化显著影响繁殖性能,提示在种猪繁殖性能方面应对这些因素加以优化和改善。To study the effect of sow breeds and its physical condition in breeding on reproductive performance,the statistical analysis to breeding body condition changes and TNB of 751 Duroc,Landrace,Yorkshire,Landrace×Yorkshire and Yorkshire×Landrace sows were collected to explore the impact of sow breed on reproductive performance and analyze the correlation between body condition and reproductive performance of sows.The results showed that sow breeds significantly influenced its reproductive performance.To be specific,the TNB,NHB of 21 d,LWB and litter weight of 21 dof Landrace and Yorkshire sows were all significantly higher than that of Duroc sows.Among them TNB and NHB of 21 dsows were respectively increased 0.96 and 1.98（P〈0.05）,LWB and litter weight of 21 dimproved 7.19%and25.37%（P〈0.05）,and no significant difference（P〈0.05）was detected of that between Landrace×Yorkshire and Yorkshire×Landrace.The backfat thickness of sow in breeding significantly influenced the reproductive performance of sow.The backfat thicknesses of Landrace and Yorkshire in hybridation,pregnancy of 30 d,delivery periods and weaned piglets of 21 dwere all significantly higher than that of Duroc,improving 6.63～12.31%（P〈0.05）4pitch nodes higher than that of the binary sows,Landrace×Yorkshire and Yorkshire×Landrace,and the differences were not significant（P〈0.05）.The backfat thickness of sow in gestation and lactation periods were significantly related（P〈0.01）with reproductive traits such as TNB,number of born alive,LWB,21 dlitter weight,etc.In conclusion,sow breeds and its body condition changes in reproducing period influences the reproductive performance significantly,implying that improvement and optimization of these can affect the reproductive performance of sows.
