Abstract

The Norik of Muran, a unique draught horse bred in Slovakia, belongs to country's biodiversity treasures. The genetic diversity of this horse type was evaluated on the basis of indicators derived from the common ancestry and the probability of gene origin. The pedigree file of the analyzed horses involved 115 individuals (15 stallions and 100 mares). The number of complete generations was 4.49 on average. The maximum number of ancestor generations at the examined population of living horses was 5.38 and the equivalent number in the generation of ancestors was 5.14. The highest average length of the generation interval was 10.97 years in the father-son direction compared to father-daughter (9.74), mother-son (10.87), and mother-daughter (8.99 years - the lowest average length). The generation interval overall average length was 10.14 years. The total coefficient of relatedness was 1.72% on average. The efficient number of core ancestors evenly used in breeding in comparison with the core ancestors mildly decreased to 198. Therefore the Austrian Norik incorporation in the breeding program is the opportunity how to maintain genetic diversity.
