In this study, we conducted a single-nucleotide polymorphism (SNP) survey of DGAT1 and CAPN1 genes on pure Australian imported Brahman (BRA) and crossbred cows between Brahman cows and Blanc Blue Belge bulls (BBB), Charolais (CHA) and Red Angus (RA). The SNP were made using the restriction enzyme shear pcr cleavage (PCR-RFLP). A total of 142 cows including: 37 BRA cows, 34 BRAxBBB crosses, 38 BRAxRA crosses, and 33 BRAxCHA crosses. The results showed that K232A polymorphism of DGAT1 gene allen type mainly K all accounted for 68.42% (BRAxRA) to 93.24% (BRA). The AA genotype only occurred in an individual in the BRAxBBB crossbred group (4.04%). For the g.5709 C> G polymorphism point in the CAPN1 gene, the CC genotype also appeared only in an individual of BRAxBBB cross-bred cow and was not found in other groups. Besides, the G allele frequency is quite high, from 66.73% (BRAxBBB) to 88.64% (BRAxCHA). The present study shows the prevalence of genotypes in imported Brahman and crossbred cattle between Brahman and other foreign beef breeds. The obtained results can be applied in selecting the superior genotype cows in the future
