Association between Stearoyl CoA Desaturase (SCD) Gene Polymorphisms and Milk Production in Holstein Cattle Breed

The SCD gene is a significant component of the leptin signaling pathway. has also been suggested as candidate essential that can change ratio saturated to unsaturated fatty acids in milk and increase amount conjugated linoleic acid, which thought have anti-cancer properties. current research was carried out on Holstein cows determine association between (Stearoyl-Coenzyme A Desaturase) polymorphism total yield at 305 days (TMY305) daily (DMY). identified using PCR-RFLP technique SatI restriction enzyme for genotyping SNP c.878T>C exon 5. TT, TC, CC genotype frequencies were 0.21, 0.50, 0.29 respectively. While allele T C 0.46 0.54, According Chi-square test results, SCD/c.878T>C distribution Hardy-Weinberg disequilibrium (P<0.05). Statistical analysis indicated TMY305 TC genotypes showed higher mean compared TT genotypes.
