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.
