摘 要:为研究水貂的繁殖率,避免母貂空怀,2010年3月320日对大连名威貂业有限公司配种期种貂精液进行了检查,结果表明:2 933只种公貂中有103只无精或死精,占种公貂总数的3.51%。说明做好精液检查是提高水貂妊娠率和产仔率的关键。如果采用同一只公貂复配,可降低母貂空怀率17.55%,能有效提高水貂的繁殖率。All sperm of breeding minks were examined in breeding period in Dalian Mingwei Mink Limited Corporation from 3rd to 20th Mar.2010.The results indicated that 103 aspermia or necrospermia animals were observed from 2 933 breeding minks,it accounted for 3.15% of the total breeding minks.Sperm examination is one of the most important works in mink production.To improve pregnancy rate and parturition rate,the key step is to examine the sperm.If the same male mink was rebreed,nonpregnant rate was decreased 17.55% of female mink,and reproduction rate was increased effectively.
