Aim. To study the genetic structure of populations of cattle Polish Red breed genes for kappa-casein and beta-lactoglobulin. Methods. Identification of individual genotypes of animals studied breed was performed by PCR-RFLP analysis. Results. Investigated populations were characterized by high frequency of desired alleles A for gene CSN3 and B for gene BLG. Conclusions. For Red Polish breed found significant genetic potential for milk production indices.
Key words: Polish Red breed, kappa-casein, beta-lactoglobulin, heterozygosity.
