摘要
为探究不同品种牦牛种公牛间的精液品质差异,本试验对青海省牦牛繁育推广服务中心饲养的野牦牛、大通牦牛和阿什旦牦牛的采精量、鲜精活力、精子密度、冻后活力、前进运动精子数和精子畸形率6项指标进行对比分析。结果显示,不同品种牦牛种公牛的精子密度差异显著(P<0.01);鲜精活力差异极显著(P<0.05)。其中,野牦牛精子密度最高(15.00±5.00)亿/毫升,大通牦牛鲜精活力最优70.00%±3.49%;而采精量、冻后活力、前进运动精子数和精子畸形率在品种间无显著差异(P>0.05)。大通牦牛冻后活力40.72%±2.04%略高于其他品种,且精子畸形率最低12.00%±2.66%,综合精液品质表现最佳。
In order to explore the differences in semen quality among different breeds of yaks and bulls,this study compared and analyzed six indicators,including semen collection,fresh sperm vitality,sperm density,post freezing vitality,forward movement sperm count,and sperm deformity rate,of wild yaks,Datong yaks,and Ashdan yaks raised by Qinghai Yak Breeding and promotion Service Center.The results showed that there were significant differences in sperm density(P<0.01)and fresh sperm vitality(P<0.05)among different breeds of bulls,with wild yak having the highest sperm density(15.00±5.00)hundred million/mL and Datong yak having the best fresh sperm vitality 70.00%±3.49%;However,there were no significant differences(P>0.05)in sperm collection volume,post freezing vitality,forward movement sperm count,and sperm deformity rate among the varieties.The frozen vitality of Datong yak 40.72%±2.04%is slightly higher than other breeds,and the sperm deformity rate is the lowest 12.00%±2.66%,with the best overall semen quality performance.
