摘　　要：为了研究繁殖母猪妊娠期间背膘厚对繁殖性能的影响,通过跟踪监测270头长大(或大长)二元杂交母猪于断奶时、妊娠中期(妊娠50 d)和临产前(妊娠112 d)的背膘厚度及产仔性能数据,分析妊娠母猪不同阶段背膘厚度与产仔性能的关联性。结果表明:母猪背膘厚度为14~17 mm时产仔性能(总产仔数、活仔数及健仔数)均高于背膘厚度小于14 mm或大于17 mm的母猪,且窝平均产弱仔数、死胎数和产木乃伊胎数均低。结果提示,养猪生产中可通过营养调控母猪背膘厚度提升繁殖母猪群的体况达标率,背膘厚度控制在14~17 mm有利于发挥母猪的产仔性能。This study was to investigate how the backfat thickness of a pregnant sow affects its reproductive performance. In this study, we monitored the backfat thickness in weaning, mid-term pregnancy(50 d) and near parturition(112 d) and reproductive performance of 270 Landrace × Yorkshire(or Yorkshire × Landrace) sows, and analyzed the correlation between their backfat thickness and their reproductive performance at different stages of pregnancy. The results showed that the reproductive performance(total litter size, living piglets and healthy litter size) of the sows with backfat thickness of 14 to 17 mm was the best, and their numbers of weak piglets, stillborn foetus of litter size and mummies were fewer, than the sows with backfat thickness of less than 14 mm or more than 17 mm. These results suggested that appropriate backfat thickness in gestational sows under proper nutritional management could improve their reproductive performance and reduce the number of weak litters, stillbirths and mummies. And the recommended backfat thickness of pregnant sows was 14 to 17 mm.
