Global studies show the effect of polymorphism of selected genes on dairy production and fatty acid spectrum. The aim of the diploma thesis was genotyping of candidate FASN locus with a focus on milk yield and fatty acid spectrum depending on genotype. The thesis describes the characteristics of cow's milk, milk fat and fatty acids in milk fat. Furthermore, the thesis deals with the genome of cattle and the potential influence of polymorphism of candidate genes affecting fatty acids of milk fat. Genotypes for FASN were determined by the PCR-RFLP method, the milk yield of selected dairy cattle was statistically evaluated according to the milk production indices for 1st lactation in individual breeds, and the determination of fatty acids was performed by spectrophotometry followed by statistical evaluation. The resulting genotypes in selected breeds were only two, the GG genotype with a higher relative frequency than the genotype AG. There is no statistically significant difference between FASN genotypes depending on the milk yield and the fatty acids spectrum.
