Abstract
Purpose of research is to estimate effective population size (Ne) of autochthonous cattle breed busha with pedigree data. Numerical strength of busha population is continuosly increasing and at the end of 2011 (CAA, 2012) the number of breeding heads is 341, i.e. 33 bulls and 308 cows. According to international classification of endangerness (FAO), Croatian population of busha breed is categorized in 2011 as „endangered – category K3“. With goal of more reliable estimation Ne, several methodologies and different types of pedigrees were used. Actual genetic variability is not result of successful conservation program, but poor informativity (length) and completiveness of pedigree and small number of known ancestor generation which confirm low value of equivalent of complete generations (1,41). Results of research of busha Ne by pedigree analysis give useful informations in monitoring of genetic diversity, but also confirm the fact that pedigree data can often be defective in NE estimation, i.e. genetic variability. In this cases, only methods of molecular genetic provide more reliable information about genetic variability on DNA structure level, and that is also the case with autochthonous cattle breed busha.
