Abstract
ObjectiveTo estimate effect of single nucleotide polymorphisms on the intramuscular fat content (IMF) of Hungarian Simmental bulls.MethodsGenotypes were determined on high-density Illumina Bovine DNA Chip. After slaughtering of animals, chemical percentage of intramuscular fat was determined from longissimus dorsi muscle. A multi-locus mixed-model was applied for statistical analyses.ResultsAnalyses revealed four loci (rs43284251, rs109210955, rs41630030, and rs41642251) to be highly associated (−log10P>12) with IMF located on chromosome 1, 6, 13, and 17, respectively. The frequency of their minor alleles was 0.426, 0.221, 0.162, and 0.106.ConclusionThe loci above can be useful in selection programs and gives the possibility to assist selection by molecular tools.
