摘 要:对母猪采取人工授精,使用不同精子数会影响母猪繁殖性能。试验选择里岔黑猪经产母猪为实验对象,按照随机分组原则进行组合测试。实验结果显示,使用精子数20亿和40亿的母猪情期受胎率、分娩率、平均产仔猪数、平均产活仔猪数、仔猪平均初生重差异不显著(P>0.05)。artificial insemination was performed on sows.Different sperm counts would affect the reproductive performance of sows.In this experiment,the sows of licha black pig were selected as the experimental objects,and the combined test was carried out according to the principle of random grouping.The results showed that there was no signifi cant diff erence in gestation rate,delivery rate,average number of piglets,average number of live piglets and average birth weight between sows with sperm counts of 2 billion and 4 billion(P>0.05).
