Associations of polymorphisms in bovine DGAT1, FABP4, FASN, and PPARGC1A genes with intramuscular fat content and the fatty acid composition of muscle and subcutaneous fat in Fleckvieh bulls

Popis výsledku v původním jazyce

Allelic and genotypic distribution of polymorphisms in diacylglycerol acyltransferase 1 (DGAT1), fatty acid binding protein 4 (FABP4), fatty acid synthase (FASN), and peroxisome proliferator-activated receptor-γ coactivator-1α (PPARGC1A) genes were assessed in 679 Fleckvieh bulls. Single-locus genotype effects and the combined effect of the two polymorphisms within the FASN gene were evaluated for association with the intramuscular fat content and fatty acid profile determined in muscle and subcutaneous fat. The FASN (g.16024GNA) and FASN (g.17924ANG) polymorphisms were significantly associatedmainlywith C14:0, C16:0, and C18:1 n-9 concentrations aswell as with the atherogenic index. The proportion of explained phenotypic variation markedly increased when the effect of a combination of the two polymorphisms within the FASN gene was tested, with the highest values of 8.6% and 14.8%, respectively, observed for C14:0 in muscle and subcutaneous fat. With a focus on improving the fatty acid composition of beef, the results of this study provide valuable information about the markers applicable in marker-assisted selection.
