| 摘 要： | 采用PIRA-PCR和RFLP法检测204头中国荷斯坦母牛生长激素受体(growth hormone receptor,GHR)基因F279Y突变,并分析其与产奶性状的关系。结果在中国荷斯坦母牛中检测到GHR基因F279Y突变,3种基因型TT、TA和AA的频率分别为0.461、0.495和0.044,等位基因T和A的频率分别为0.708和0.292。分析表明,AA基因型个体305天产奶量显著高于TA和TT基因型(P0.05);TT基因型个体乳脂率显著高于AA基因型个体(P0.05),乳蛋白率极显著高于TA和AA基因型个体(P0.01)。A等位基因对305天产奶量有正加性效应,显性度相对较高;而对其他4个乳成分性状有负加性效应,显性度相对较低。等位基因A具有提高产奶量的效应,等位基因T具有提高乳成分的效应。本研究初步表明F279Y突变可以用于中国荷斯坦牛产奶性状的标记辅助选择。

| Abstract: | milk composition traits with a lower dominance. A is the dominant allele for milk yield, while T is the dominant allele for milk composition. These results preliminarily indicated that the F279Y mutation of the GHR gene could be used in molecular marker-assisted selection programs of milk production traits in Holstein cows. |
