摘 要:遗传缺陷病对奶牛的生产和繁殖能力具有重要影响,如果不及时检测和筛选,可能会导致胚胎死亡和犊牛畸形,进而影响牛场的经济效益。为了保障荷斯坦牛的良种选择和群体遗传改良,加强对遗传缺陷病的检测是非常关键的。本研究利用微流控SNP芯片技术,对河北省种公牛站的38头荷斯坦种公牛冻精进行了9种遗传缺陷基因筛查,并对其分布情况进行探析。结果显示,CVM、HH1、HH3、BS、HH5、HH6遗传缺陷的携带率分别为2.60%、2.60%、10.50%、2.60%、7.90%和5.30%,未发现HH4、BLAD和HCD的携带者。结果表明,河北地区种公牛群体中存在一定比例的遗传缺陷携带者,为避免遗传缺陷给奶牛生产带来不利影响,建议牛场在使用冻精时,应采取科学的选种选配措施。Embryonic mortality and calf malformations due to genetic defective diseases are among the most important causes of dairy production.Strengthening the detection of genetic defect disease has a crucial role in the selection of improved varieties of Holstein cattle in China.In this study,we used the established molecular detection method of 9 defective genes to detect the genetic defects of 38 bull frozen sperm from the breeding station of Hebei province,and analyzed the distribution of genetic defects in Holstein bulls.The results showed that the carrying rates of CVM,HH1,HH3,BS,HH5 and HH6 were 2.60%,2.60%,10.50%,2.60%,7.90% and 5.30%,respectively,and no carriers of HH4,BLAD and HCD were found.The results showed that there were a certain proportion of genetic defect carriers in breeding bulls in Hebei area.It was suggested that scientific seed selection and selection measures should be taken to avoid the negative effects of genetic defect on dairy cow production when using frozen sperm.
