Influência da mutação K232A do gene DGAT1 na deposição de gordura intramuscular em bovinos

Abstract

This literature review aims to bring information about the K232A mutation, which is related to the deposition of intramuscular fat and milk. With the data acquired by other authors, it was possible to collect information, identifying the allele frequency in relation to the K232A locus, where the A allele is wild for taurine breeds and the K allele in zebu breeds. In addition, some zebu breeds such as Nelore and Guzerá are monomorphic, but in the case of the Nelore breed, crossing with taurine breeds, brought significant levels of heterozygosity, together with differences in the carcass, such as shear force and marbling, where there were significant changes.
