POLIMORFIZM W GENACH BMAP-27 I BMAP-28 ORAZ ICH ZWIĄZEK Z CECHAMI PRODUKCJI MLEKA U BYDŁA

Abstract

The study aimed to analyze polymorphisms located in exon 4 of the CATHL5 gene encoding the BMAP-28 protein and in exon 4 of the CATHL6 gene encoding the BMAP-27 protein concerning milk performance parameters, such as milk yield, fat, protein, and lactose content and somatic cell count in milk. The PCR-RFLP method using the ACRS technique was used in the study to create a cleavage site for enzymes. Based on the results of genotyping, results for individual SNPs were obtained, with statistically significant differences at the P ≤ 0.05 and P ≤ 0.01. Between individual genotypes of the studied polymorphisms and selected traits of milk production.
