Sažetak
Recognizing and affirmation of autochthonism are basic points protection breeds, whereas is ground of continuity of breeding work which loss genetic rarity reduces to minimum. Necessary is seems the routine overview over the breeding work on autochthonous breeds in order to notice inadequacies in view of genetic and also economic sustainability. Has been analyzed genetic structure and sustainability of two autochthonous cattle breeds which are more than decades in center scientific and wider interest. The Istrian cattle has been partly consolidated in the genetic sight, beside still is unclear breeding strategy with regard to the accessible lineages. Has been estimated the level inbreeding of Istrian cattle on the basis of pedigree data is moderate level (0,0175), but the number and distribution of lineages suggest the needs of more careful implementation breeding program. Levels of inbreeding (calculated on the basis of pedigree) Slavonian syrmian podolian cattle (0,0186) points to the systematic selection work, but numerical situation of populations and distribution of herds suggest on the existing seriousness situations. Breeders unsatisfactory heights of financial stimulus, by undeveloped programs of economic use, call in question too physical sustainability populations the in situ program preservations.
