The Buffaloes are domestic animals belonging to Bubalus genus, Bovidae family and Artiodactyla order. Provide meat, milk and workforce. Are quite adapted to the climatic conditions of the state of Pará, producing well in those conditions. However, producers still need tested animals for production characteristics. There were used the technique of SSCP (single-strand conformation polymorphism) and SNP markers (single nucleotideo polymorphism), in order to characterize the 83 buffaloes from murrah and Mediterranean breeds. For the DGAT1, occured allelic frequency of 0.741 for the allele A, 0.253 for the allele B and 0.01 for the allele C. The genotypic frequencies were 0.54 for the AA genotype, 0.39 for the AB genotype, 0.06 for the BB genotype and 0.01 for the AC genotype. For the GH gene was found only one genotype. The DGAT1 gene showed considerable genetic variation and detects the presence of SNPs.
