| 摘 要： | 为研究妊娠母猪膘情与繁殖性能的关系,试验随机选用32头妊娠母猪,用B超活体测定其产前3 d倒数3、4肋骨间、胸腰椎结合处、腰荐椎结合处偏离背中线5~8 cm处背膘厚,并与其窝产仔数、产活仔数、死胎数、、仔猪初生重、初生窝重、18日龄断奶重、断奶窝重及断奶后发情天数等指标进行比较。结果显示,背膘厚度较薄组各项繁殖指标普遍优于背膘厚组,说明保持适当膘情对妊娠母猪繁殖性能的提高具有促进作用。

| Abstract: | This experiment was carried out with the relationship between the back-fat thickness of pregnant sows and reproductive performance.Choosing 32 pregnant sows,alive determined the back-fat thickness at the points among backwards 3,4 rib,the connection between thoracic and lumbar vertebrae,and the the connection between the lumbar vertebrae and sacrum by type-B ultrasonic device,and compared with litter size,number of born alive,number of dead embryo,brith weight,brith wt.of litter,weaning wt.at 18 d,weaning w... |
