Genotyping offers a promising avenue for identifying the healthy reproductive system in cows. The healthy reproductive system in cows is determined by measuring the level of ovulation and by identifying the type polymorphism of specific genes.
The aim of the article is to explore how polymorphism of Follicle Stimulating Hormone Receptor (FSHR) and Luteinizing Hormone/Choriogonadotropin Receptor (LHCGR) genes affect the reproduction trait of Holstein cows.
Here we define a reproducible protocol to genotype and identify the polymorphism in specific genes from the extracted DNA of cows.
The results of genotyping showed that the only C allele (CC genotype) was observed in 100% of cows at the LHCGR locus, and three genotypes were observed at the FSHR locus (CC – 67.74%, CG - 9.03%, GG – 23.22%). In cows with the CC genotype at the FSHR locus, the hormone concentration during ovulation was 1.1 – 2.5 ng/ml, which is within the physiological range for healthy reproduction.
Cows with the CC genotype at the FSHR locus have a healthy course of the ovulation process, therefore good reproduction.

Key words: Genotyping, Ovulation, LHCGR, FSHR, Polymorphism
