摘要
以16头蓝白花种公牛为对象,对其采精适宜年龄及不同年龄对冻精质量的影响进行了研究。结果表明,蓝白花种公牛最初采精以20月龄为宜,3～6岁精液质量最好,7岁后精液质量呈下降趋势。
The effects of age on frozen sperm quality of Blue-White beef cattle were studied in this paper. The result showed that the optimum age of collecting sperm was 20 months old. And the sperm quality of Blue-White beef cattle was better from 3 to 6 years old than other periods, and it took on a decline tendency with the increasing of age.
