AbstractThe study analyzed three SNP polymorphisms located in exon 2 of the corticotropin-coding genes (rs110167397, rs381116984, rs109244394), later referred to as CRH1, CRH2, CRH3, respectively. The research was conducted in a Salers cattle herd. Identification of genotypes of individual animals was carried out using polymerase chain reaction - restriction fragments length polymorphism (PCR-RFLP). The heterozygous genotypes of all analyzed polymorphisms they determined the most extensive body mass of the analyzed animals. Other traits, such as cow size, muscularity, hip height and chest girth, were the most favorable for homozygous GG individuals concerning CRH1 polymorphism. Studying the relationship between CRH2 polymorphism and the animals with the genotype TT was preferred for traits such as muscularity and chest girth. It was shown that the CRH3 polymorphism significantly affected the muscularity and higher values of the zoometric measurement (hip height, chest girth) in the case of cows with the genotype CC. Significant differences were found in the study (p 0.01; p 0.05).
