Conteúdo:	A new, quick, and inexpensive method for detecting the bovine acyl-CoA:diacylglycerol acyltransferase1 (DGAT1) polymorphism (K232A) through tetra-primer amplification refractory mutation system by PCR (ARMS-PCR) was developed in the present investigation. The DGAT1 gene was recently identified as underlying variation in milk production traits. To date, PCR techniques such as PCR-RFLP have been used for detecting the DGAT1 K232A polymorphism, despite being expensive and laborious. The method proposed here, a tetra-primer ARMS-PCR, showed 100% sensitivity and specificity when compared with PCR-RFLP results obtained in a sample of 80 animals tested in a double-blind system. Our results suggest that the use of tetra-primer ARMS-PCR for DGAT1 K232A polymorphism genotyping could greatly reduce costs providing information for both research purposes and for dairy cattle breeders who perform DGAT1 genotyping for gene-assisted selection.
