MENDELNET <strong>2013</strong>ASSOCIATION OF SINGLE NUCLEOTIDE POLYMORPHISM IN TG,LEP AND SCD1 GENES WITH CARCASS TRAITS IN HIGHLANDAND GALLOWAY CATTLEHorecký Č., Knoll A.Department of Animal Morphology, Physiology and Genetics, Faculty of Agronomy,Mendel University in Brno, Zemedelska 1, 613 00 Brno, Czech RepublicE-mail: cenek.horecky@mendelu.czABSTRACTThis work deals with the influence of selected polymorphisms in TG, LEP and SCD1 genes onquality of beef (composition and fatty acids content).Testing of selected polymorphisms for meat quality was carried out on 19 bulls and 58 mothers ofextensive breeds of cattle (Galloway and Highland). For detection of SNPs PCR-RFLP method wasused. In a group of 19 bulls and 58 mothers the frequency of alleles and genotypes was detected.Based on the association analysis no significant influence was found on meat composition withemphasis on IMF content. The polymorphisms in TG, LEP and SCD1 genes differs significantly infatty acid composition. C422T polymorphism of the TG gene has a significant effect (p
