abstract
The nucleotide variation of Diacylglycerol acyltransferase 1 (DGAT1) and Stearoyl-CoA desaturase 1 (SCD1) were reported to correlate to beef quality parameter. This study aimed to investigate and analyze the Single nucleotide polymorphism (SNPs) of DGAT1 and SCD1 in Vietnamese native cattle, Sindhi cattle and Brahman crossbred cattle. The PCR-RFLP was applied to analyze SNPs of DGAT1 for total 209 cattle (including 84 Vietnamese native cattle, 69 Sindhi cattle and 56 Brahman crossbred cattle). The results demonstrated that the Single nucleotide polymorphism of DGAT1 was located at K232A position. The frequency of A allele in Vietnamese native cattle was 56.03% which was lower than Sindhi cattle (62.83%).
