Increased content of monounsaturated fatty acids with low melting points in cattle milk and meat known to strongly affect their taste and nutritional value. Steroyl-CoA-desaturase (SCD) is a key enzyme in the biosynthesis of monounsaturated fatty acids. The gene encoding SCD in cattle is located on chromosome 26 and consists of 6 exons and 5 introns and is expressed in the cells of cow udder, adipose, muscles and other tissues. To date, several SNPs in cattle SCD gene have been found. For SNP rs41255693 (g.10329T > C), a correlation was shown between the content of monounsaturated fatty acids in cattle milk/meat and milk productivity. This article describes the development of a real-time PCR assay for genotyping SNP rs41255693 in cattle SCD gene with allele-specific TaqMan probes. The use of this assay allows to significantly reduce the time needed for cattle genotyping compared to the commonly used PCR-RFLP method.
