Abstract
The aim of this study was to estimate genetic characteristics of cows herd based on polymorphism in the promoter region of IGF-1 gene as well as determine possible relationships between detected polymorphism and milk performance traits. Investigations were carried out on 185 cows of Polish Holstein-Fresian breed, variety black-and-white. Polymorphism of IGF-1 gene was determined by use ACRS-PCR method. The comparison between the number of observed genotypes and the theoretical number of genotypes showed loss of genetic equilibrium in investigated population. Heterozygosity of analyzed herd was 0.64. Analyzing milk performance traits in relation to individual genotypes it was affirmed that genotype CC in most cases was associated with higher values of examined traits, however these differences were not confirmed statistically.
