Abstract

The objective of this study was to estimate the effect of leptin, thyroglobulin (TG) and acylCoA-diacylglycerol-acyltransferase 1 (DGAT1) loci and linoleic acid supplemented diet on the marbling of meat in the Hungarian Angus population. All genotypes were determined by PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) assay. At leptin and TG loci TT bulls showed the highest fat percentage values in the musculus longissimus dorsi (LD) and musculus semitendinosus (ST), the difference between CC and TT genotypes was significant (p<0.05). DGAT1 AA/AA bulls had significantly higher (p<0.05) intramuscular fat content values than other genotypes. The sunflower supplemented group of bulls presented significantly higher (p<0.05) fat percentage values for LD, than the control group.
