BREEDING SYSTEMATIZATION OF AUTOCHTHONOUS CATTLE BREED BUSHA

Buša je jedna od tri hrvatske izvorne pasmine goveda i prema veličini populacije druga je izvorna pasmina goveda u Republici Hrvatskoj. Za vjerodostojno i uspješno plansko vođenje uzgoja i provedbu uzgojnog programa, nužno je učiniti sistematizaciju uzgoja temeljem rodovničkih podataka, a plansko vođenje uzgoja (planski pripust) organizirati prema linijama bikova i rodovima krava. Iz tog razloga provedena je sistematizacija uzgoja buše (izgradnja rodovnika), a rezultat sistematizacije je definiranje 24 linije bikova i 154 rodova krava. Sistematiziran uzgoj prema linijama i rodovima omogućava plansko vođenje uzgoja u cilju sprečavanja reduciranja genetske varijabilnosti, vjerodostojnije utvrđivanje demografskih parametara, procjenu kompletne genetske varijabilnosti pasmine, efikasniju provedbu molekularnih istraživanja uz znatno manje troškove, smanjuje troškove pohrane genetskog materijala u banku gena te omogućava kontrolu uzgoja obzirom na izlučenje grla iz uzgoja (klanje).Busha is one of three Croatian autochthonous breeds of cattle and by population size is the second autochthonous cattle bree in the Republic of Croatia. For reliable and successful planned managing of breeding and implementation of breeding program, it is necessary to systemize breeding on the basis of pedigree data, and organize planned mating by sire lines and dam lines. For this reason, systematization of Busha breed has been conducted (pedigree building), and the result of systematization is defining 24 sire lines and 154 dam lines. Systemized breed by sire lines and dam lines allows planned leading of breeding with goal of avoiding reduction of genetic variability, more reliable determination of demographic parameters, evaluation of complete genetic variability of the breed, more efficient application of molecular research with significantly decreased costs, storage of genetic material in the gene bank, and provides control of breeding regarding to exclusion of heads out of the breeding (slaughtering)
