Abstract
Casein is a highly digestible protein in milk. CSN2 is one of the most abundant proteins in total casein at 35%. CSN2 is CSN2 is important gene for milk properties. The aim of this study is observe the effect of these SNPs on milk quality such as Solid Non-Fat, Fat, Density, Lactose, Solid, and Protein in exon 6. The CSN2 gene polymorphism was analyzed using sanger sequencing method. In this study, the SNP (g.6683G>A) in exon 6 did not change amino acids or in other words synonymous mutation. We found the effect of lactation but no effect of genotype (GG, GA, AA). Therefore, we suggested that research on composite genotypes in CSN2 is carried out to obtain better results.
