SLC27A1 SNPs in relation to breeding value of milk production traits in Polish Holstein-Friesian cows
Journal Title: Animal Science Papers and Reports - Year 2013, Vol 31, Issue 4
Abstract
The aim of the study was to investigate associations between SLC27A1 genotypes and estimated breeding value of milk production traits (milk, fat and protein yield, kg; fat and protein content, %) in the Polish Holstein-Friesian cows’ herd. Three single nucleotide polymorphisms were genotyped, the g.14996C>G. in the exon 3, g.14791C>T in exon 4 and g.14589A>G in exon 5 of SLC27A1 gene. The genotype and allele frequencies for each polymorphism and the SLC27A1 haplotype frequencies were estimated in the examined herd. Significant relations between the SLC27A1 g.14791C>T SNP and breeding value for protein content were found. The results indicate that selection for the SLC27A1-CC individuals might contribute to increased protein content of milk in Polish Holstein- Friesian cows. Further studies are needed to confirm these results.
