Genetic Structure’s Investigation of the Ukrainian Population of the Polish Red Breed Cattle by Quantitative Trait Loci

Abstract

Aim. To investigate the genetic structure of the Polish Red breed cattle population that is being reproduced in Ukraine by 5 genes participating in the formation of qualitative and quantitative performance indicators of cattle. Methods. Defi nition of individual genotypes of the animals was performed using polymerase chain reaction (PCR) followed by determination of restriction fragment length polymorphism (RFLP analysis). Results. The high frequency of desirable alleles in the genes of kappa-casein and beta-lactoglobulin has been reported for the investigated population. Conclusions. The signifi cant genetic potential of the Polish Red breed cattle by milk production was stated.
