Sažetak
The purpose of the study was to show the genetic structure and diversity parameters of Croatian autochthonous pig breeds based on available literature data. The preservation of genetic diversity of autochthonous breeds has recently been increasingly emphasized due to their cultural and genetic importance. Their resistance to disease and their adaptability to different conditions can play an important role in the improvement of constitutive characteristics of hybrid and noble pig breeds. The increased use of hybrids and modern breeds in breeding and production resulted in a decrease in the populations of autochthonous breeds and a change in their genetic structure. As a consequence, the population of autochthonous breeds has a very high rate of inbreeding, low genetic diversity and very often in these populations there is a bottleneck process. In order to maintain genetic diversity of Croatian autochthonous pig breeds, it is necessary to carry out planned breeding with control of origin, monitor sustainable inbreeding rate and carry out optimum contribution selection in breeding programmes.
