Abstract:
The SNP loci of ACOX1 gene in 83 China Holstein cows were detected by PCR amplifica-tion and direct sequencing,and the association between the genetic polymorphism loci of ACOX 1 gene and milk quality traits of China Holstein cows was analyzed by SPSS 25.0 software.The re-sults showed that a SNP locus I3-2 267 G→C was found in the third intron of ACOX1 gene,it was moderately polymorphic and in Hardy Weinberg equilibrium in the population.By correlation anal-ysis,it was found that the SNP locus was significantly related to the somatic cell content and cor-rected milk quantity of dairy cows.The I3-2 267 G→C locus of ACOX1 gene can be used as a mo-lecular marker of quality traits of Holstein cows in China,and provide reference for the study of quality traits of Holstein cows in China.
