Estimation of inbreeding coefficient and generation interval in Pag Sheep – baseline for development of optimum contribution selection

The aim of the study was to estimate coefficient of inbreeding (FPED) and generation interval (GI) in the population of Pag sheep breed in order to provide a scientifically based background for implementation of optimum contribution selection. The average FPED was 6%, with inconsistent trend in the last decade, and GI was estimated to be 4.44 years. The FPED was higher than reported for majority of few well known European dairy breeds, while the GI was in line with the reports. The estimated FPED calls for attention of the breeders to keep it as low as possible in the future, preferably by following the basic principles of the optimum contribution selection.
