Sažetak
Register of autochthonous cattle breed busha was founded in 2003. and till today it is consisted of 1020 heads. In whole pedigree 329 founders and 249 half-founders are determined. The number of founders in reference population is 285, half-founders 219, and ancestors 255, and 50% of genetic variability explain 17 ancestors and 20 founders. The largest number of complete generations 1,41 which indicates poor informativity and completness of pedigree. Part of significant ancestors gave its contribution to genetic variability as founder, but not as ancestor which indicates loss of part of genetic variability. Increasing of inbreeding rate and connections, ratios of certain parameters of gene origin (fe/fa, fg/fe, fe/f) and decreasing of contribution of number of founders in reference population compared to the whole pedigree, indicate the loss of genetic variability in population. Pedigree analysis results indicate that in purpose of preservation of genetic variability, it is necessary and urgent creating of quality breeding progam, breeding plan and conservation strategy, based on pedigree analysis and method of molecular genetic.
