| 摘 要： | 目的]研究季节、品种两大因素对成年公猪精液量及精子活力的影响效应。方法]对21头长白猪和26头大白猪在一年内不同季节的精液量和精子活力进行观察和测定，并对这些精液品质进行统计学分析。结果]季节对成年公猪精液量的影响达到显著水平（P〈0．05），但2个品种对精液量的影响没有显著差异（P〉O．05），其中长白猪的精液量在春季最多，秋、冬、夏依次减少，而大白猪的精液量在秋季最多，夏、春、冬三季则依次减少；季节和品种对成年公猪精子活力的影响均不显著（P〉O．05），但是长白猪和大白猪的精子活力均在春季最高，而夏季最低，此外一年四季长白猪的精子活力明显高于大白猪。结论]结果为提高猪场的繁殖效率和生产水平奠定基础。

| Abstract: | Objective] The research aimed to study the effects of season and variety on the semen volume and sperm motility of adult boar. Method] The se- men volume and sperm motility of 21 Landrace pigs and 26 Yorkshire pigs in different seasons were observed and de- termined. And the statistical analysis was made on these quality indices of semen. Result] The effects of different seasons on the semen volume of adult boar reached significant level （P〈0.05）, but the effects of two varieties on the semen volume were not significant （P〉0.05）. The semen volume of Landrace pigs in spring was the most, and that in autumn, winter and summer was decreased in succession. The semen volume of York- shire pigs in autumn was the most, and that in summer, spring and winter was decreased in succession. The effects of season and variety on the sperm motility of adult boar were not significant （P〉 0.05）, but the sperm motility of Landrace pigs and Yorkshire pigs reached the maximum values in spring and reached the minimum values in summer. Further- more, the sperm motility of Landrace pigs in four seasons was obviously higher than that of Yorkshire pigs. Conclusion] The results laid the foundation for im- proving the reproductive efficiency and production level of pig farms. |
