The aim of this study is to estimiate the associations between the ANXA9, FABP3, and FABP4 genotypes and the breeding value for milk production traits (yields of milk, protein, and fat, as well as protein and fat percentage) in 975 Polish Holstein-Friesian cows. The frequencies of genotypes and alleles were determined. Statistically significant relations between the ANXA9 SNP and the breeding value for fat content, as well as the FABP4 SNP and the breeding value for protein content were found. The results indicated that selection for the ANXA9 GG and FABP4 GG animals might contribute to an decreased fat content and increased protein content in milk, respectively, in Polish Holstein-Friesian cows. Although verification in the further studies is needed.
本研究旨在估计975头波兰荷斯坦-弗里生奶牛中ANXA9、FABP3和FABP4基因的基因型与产奶性状（产奶量、蛋白质产量、脂肪产量以及蛋白质和脂肪百分比）育种值之间的关联。确定了基因型和等位基因的频率。发现ANXA9 SNP与脂肪含量育种值之间以及FABP4 SNP与蛋白质含量育种值之间存在统计学上的显著关系。结果表明，选择ANXA9基因GG型和FABP4基因GG型的奶牛可能分别导致波兰荷斯坦-弗里生奶牛乳中脂肪含量降低和蛋白质含量增加。不过还需要进一步研究进行验证。
