Abstrakt
The objective of the study was to determine genetic differentiation of the current Hucul horse population and to analyse gene frequency changes during the course of the breeding programme for this breed. A total of 5000 Hucul horses raised in Poland were investigated. Based on the identified erythrocyte antigens and electrophoretic variants of blood proteins and enzymes in 14 loci, the allele frequency of the analysed markers was calculated in two groups of horses born before 2001 and during 2001–2010. Statistically significant differences were found in allele frequencies in both groups of animals. The investigated population is in Hardy-Weinberg genetic equilibrium except for esterase. The average degree of heterozygosity in horses increased to 0.413, while the average inbreeding coefficient in the herd, calculated from allele frequencies at 7 protein loci, decreased to 0.0118.
