Abstract

Sows (n=1205) were artificially inseminated with semen from single sires (n=166). Semen was previously analysed for sperm concentration, motility, velocity, morphology (using DIC microscopy) and membrane integrity, sperm clump score, temperature on arrival and pH. Percent normal sperm influenced both numbers of pigs born alive (P<0.01) and litter size (P<0.05) which, in turn, was also influenced by abnormal sperm head morphology (P<0.05) and retained distal cytoplasmic droplets (P<0.01). Percent stillbirths were influenced by sperm flagellar beat cross frequency (P<0.05) and semen arrival temperature (P<0.05).

摘要

母猪（n=1205）接受了来自单个公猪（n=166）精液的人工授精。此前对精液进行了精子浓度、活力、速度、形态（使用相差显微镜）和膜完整性、精子团评分、到达时的温度和 pH 值的分析。正常精子的百分比影响活产仔猪的数量（P<0.01）和窝产仔数（P<0.05），而这又受到精子头部形态异常（P<0.05）和保留的远端胞质小滴（P<0.01）的影响。死胎的百分比受到精子鞭毛摆动交叉频率（P<0.05）和精液到达温度（P<0.05）的影响。
