The aim of the study was to determine the current level of inbreeding of SIKA rabbits in Slovenia. The pedigree of 27.110 rabbits was analysed. There were 13.521 males and 13.589 females. Without known parents were 146 animals. Altogether, there were 1490 dams and 391 sires. For a reference population we used animals born in years 2010 and 2011. The average relationship coefficientis 7.8 %, meaning that in a completely random mating scheme the inbreeding in the next generation would be at this level. Average inbreeding coefficient in the population was 6.5 %. The effective number of ancestors was only 24, which is in contrast with the large number of known ancestors. Effective number of ancestors contributing 50 % of genes to the gene pool of the population was 9. A single animal contributes 7.3 % in males and in females 7.2 % of genes in the population gene pool.
