Abstract

The objective of this study was to estimate the effect of single-nucleotide polymorphisms (SNPs) on the breeding value of fertility (BVF) and the breeding value of beef (BVB) in Hungarian Simmental cattle. Genotypes were determined on a high-density Illumina Bovine DNA Chip. Data screening and data identification were performed by multi-locus mixed-model. Statistical analyses were carried out to find associations between individual genotypes and the investigated quality values. Three loci showed considerable association with BVF (–log10 P = 9.5, 9.9 and 14.5, respectively) on chromosomes 9, 28 and 29, respectively. The frequencies of their minor alleles (MAF) were 0.375, 0.355 and 0.354, respectively. Two loci showed association with BVB (–log10 P = 25.3 and 22.7) on chromosomes 2 and 11, respectively (their MAF were 0.438 and 0.229). The abovementioned loci provide a straightforward possibility to assist selection by molecular tools.
