Sažetak

The aim of the study was to assess genetic variability in Slovak Pinzgau breed using pedigree analysis. The whole population consisted of 8311 individuals of that 2399 living animals (2373 cows and 26 sires) in the reference population. Pedigree completeness, parameters based on probability of identity by descent and gene origin was analysed. The mean inbreeding level in the reference population was low 0.57%, mean individual increase in inbreeding 0.25% and average relatedness 1.17%. A total 141 effective founders and 51 effective ancestors were found in the reference, resp. 257 effective founders and 103 effective ancestors in the whole population. The number of 21 effective ancestor explained 50% of diversity in the reference and 51 in the whole population. The results demonstrate need for better monitoring of population and can be implemented in preparation of the strategy for development of breed.
