    Cilj rada bio je opisati genetsku strukture te parametre genetske raznolikosti autohtonih pasmina svinja Hrvatske temeljem dosadašnjih podataka u dostupnoj literaturi. Očuvanju genetske raznolikosti autohtonih pasmina se posljednjih desetljeća pridaje sve veća pozornost jer predstavljaju kulturno i genetsko nasljeđe te zbog svoje otpornosti na bolesti i prilagodljivosti različitim uvjetima mogu imati važnu ulogu u popravljanju konstitucijskih svojstava hibrida i plemenitih pasmina. Povećana uporaba hibridnih linija i plemenitih pasmina u uzgoju i proizvodnji rezultirala je smanjenjem populacija izvornih pasmina te promjenom njihove genetske strukture. Kao posljedica navedenog, populacije izvornih pasmina imaju vrlo visoku stopu uzgoja u srodstvu, nisku genetsku raznolikost te vrlo često u ovakvim populacijama dolazi do procesa „uskog grla“. U cilju održavanja genetske raznolikosti hrvatskih autohtonih pasmina svinja potrebno je provoditi plansko sparivanje uz kontrolu podrijetla, praćenje održive stope uzgoja u srodstvu te provoditi selekciju s optimiziranim doprinosom u uzgojnim programima. 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.
