Sažetak

The objective of the paper was to evaluate trends in inbreeding and genetic diversity loss of Slovak Pinzgau. Genealogic information had good informative value. Inbreeding trends were positive in pedigree as well as reference populations. Intensity of inbreeding and average relationship have not reach the level of 1 % at which inbreeding gains per generation was low in the reference population. Almost the same results were obtained in the population of cows. Sires influenced inbreeding and its gain in reference population less than cows, but higher sires average relationship may create not optimistic prognosis for future sire inbreeding development. Total loss of genetic diversity in sire group was 3.17 % at which this level was more influenced by genetic drift (2.69 %) than bottleneck.
