摘要
采用CRS-RFLP技术对中国荷斯坦牛PRL基因第4外显子C8377G位点及第4内含子T8510C位点进行单核苷酸多态性分析。最小二乘分析表明:在8377位点GG基因型个体产奶量最小二乘均值显著高于CC基因型(P<0.05),GC基因型个体乳蛋白率最小二乘均值显著高于CC基因型(P<0.05);在8510位点CC基因型个体产奶量最小二乘均值显著高于TT基因型(P<0.05)。
Single nucleotide polymorphisms of exon 4 C8377G and intron 4 T8510C of PRL gene were detected in Chinese Holstein cows by CRS-RFLP. At 8377 site, the least square mean of milk yield of this population was higher for individuals with genotype GG than that for individuals with genotype CC （P〈0.05） ; The least square mean of protein percentage of this population was higher for individuals with genotype GC than that for individuals with genotype CC （P〈0. 05）. At 8510 site, the least square mean of milk yield of this population was higher for individuals with genotype CC than that for individuals with genotype TT （P〈0.05）.
