Two polymorphisms at STAT5A gene were investigated in a sample of Agerolese cows. The aims of the present study were to estimate the allele and genotype frequencies and to investigate the relationship among genotypes and milk production traits. Milk production traits were analyzed for each animal in the first, second, third, and fourth lactation. No genetic variability was found at STAT5A/AvaI locus. At STAT5A/MslI locus, the frequencies of T and C alleles were 0.875 and 0.125, respectively. Significant differences between genotypes were found: TT cow produced a milk with a higher content of fat and protein when compared with TC.
在阿杰罗莱塞奶牛样本中研究了STAT5A基因的两个多态性。本研究的目的是估计等位基因和基因型频率，并研究基因型与产奶性状之间的关系。对每头奶牛在第一、第二、第三和第四泌乳期的产奶性状进行了分析。在STAT5A/AvaI位点未发现遗传变异性。在STAT5A/MslI位点，T和C等位基因的频率分别为0.875和0.125。发现基因型之间存在显著差异：与TC基因型奶牛相比，TT基因型奶牛所产牛奶的脂肪和蛋白质含量更高。
