2、传播病原的风险增加;且新冠疫情的不且新冠疫情的不确定性对精液的供应物流运输产生了影响。确定性对精液的供应物流运输产生了影响。Under the influence of the ASF epidemic,the pig farms introduced semen from outside,and the risk of the transmission of pathogens by the semen itself and the semen packaging increased;and the uncertainty of the corona virus epidemic had a
