摘  要：
为揭示弗莱维赫(德系西门塔尔)与荷斯坦杂交牛(以下简称弗荷杂交牛)与荷斯坦牛在抗病力遗传的差异,利用Igenity?Select Profile (ISP)奶牛遗传评估项目,选取弗荷杂交牛与荷斯坦牛各100头,以临床常见的存活力、酮病、胎衣不下、产乳热、乳房炎、真胃移位、子宫炎、牛奶体细胞数等主要性状开展遗传评估检测.结果显示弗荷杂交牛在存活力、产乳热、真胃移位、乳房炎、胎衣不下抗性遗传评估值上显著优于荷斯坦牛,统计学差异极显著(P<0.01),在体细胞数、酮病、子宫炎等抗性遗传育种值上抗性相当,统计学差异不显著(P>0.05),在生产寿命遗传评估值上显著低于荷斯坦牛,统计学差异极显著(P<0.01).本研究从基因及遗传育种角度初步揭示弗荷杂交牛与荷斯坦牛在抗病性遗传方面的差异,为弗莱维赫牛改良奶牛实现乳肉牛融合发展提供参考.

摘  要：
In order to reveal the genetic differences of disease resistance between Freivik and Holstein cattle,100 Freivik and Holstein cattle were selected by Igenity? Select Profile(ISP).The common clinical traits such as survival vigor,ketosis,fetal retention,milk fever,mastitis,transposition of the true stomach,metritis and milk somatic cell count were evaluated.The results showed that the genetic evaluation value of resistance to survival vigor,milk production fever,true stomach displacement,mastitis,and fetal overgrowth of Frank-Dutch hybrid cattle was significantly better than that of Holstein cattle,with significant statistical difference(P<0.01).The resistance was similar in genetic breeding value of resistance to somatic cell count,ketosis,metritis,etc.,with no statistically significant difference(P>0.05).The genetic evaluation value of production life was significantly lower than that of Holstein cattle,and the statistical difference was extremely significant(P<0.01).This study revealed the genetic differences of disease resistance between Frank-Dutch hybrid cattle and Holstein cattle from the aspects of genes and genetic breeding,and provided a reference for the development of milk-meat fusion in the improved dairy cows of Flevich cattle.
