| 摘 要： | 目的]为研究安徽省内地方牛种的精液品质差异,方法]试验对皖东牛、大别山牛、皖南牛3种种公牛的冬春季节所采集的精液质量进行分析与比较。结果]结果表明:射精量方面,大别山牛射精量低于皖东牛和皖南牛,差异显著(P0.05);3种牛的精液颜色都为乳白色;精子活力方面,皖南牛的原精活力相对最高,其次是皖东牛,大别山牛最低,不同牛种间差异不显著(P0.05);皖东牛的冻精解冻后活率最低,与大别山牛和皖南牛差异显著(P0.05);皖南牛冻精解冻后精子直线运动的数量最高,与皖东牛和大别山牛差异显著(P0.05);精液细菌数方面,大别山牛的每剂冻精细菌数最高,与皖东牛和皖南牛差异显著(P0.05);畸形率方面,皖东牛的精子畸形率最低,与大别山牛和皖南牛差异显著(P0.05)。结论]3种种公牛中,皖东牛与皖南牛的射精量高,皖东牛解冻后精子畸形率低,皖南牛与大别山牛解冻后精子活率高。

| Abstract: | Objective] To study the difference of semen quality of local cattle breeds in Anhui province, Method] this experiment analyzed and compared the raw and frozen semen collected from three kinds of cattle in winter and spring, namely Wandong cattle, Dabieshan cattle and Wannan cattle. Result] The results showed that the ejaculation quantity of Dabieshan cattle was significantly lower than that of Wandong cattle and Wannan cattle (P< 0.05). The semen of all three breeds was milky white. In terms of sperm motility, the sperm motility of Wannan cattle was the highest, followed by that of Wandong cattle, and that of Dabieshan cattle was the lowest. There was no significant difference between different breeds (P> 0.05). After thawing, the activity rate of Wandong cattle was the lowest, which was significantly different from Dabieshan cattle and Wannan cattle (P< 0.05). After thawing, the number of sperm moving in a straight line was the highest in Wannan cattle, which was significantly different from that in Wandong cattle and Dabieshan cattle (P< 0.05). In terms of the number of bacteria in semen, Dabieshan cattle had the highest number of bacteria in each dose of frozen semen, which was significantly different from Wandong cattle and Wannan cattle (P< 0.05). In terms of malformation rate, the sperm malformation rate of Wandong cattle was the lowest, which was significantly different from Dabieshan cattle and Wannan cattle (P< 0.05). Conclusion] Among the three kinds of bulls, Wandong cattle and Wannan cattle had high ejaculation quantity, low sperm malformation rate after thawing of Wandong cattle, and high sperm motility rate after thawing of Wannan cattle and Dabieshan cattle. |
