The research was aimed at determination of genetic variability of Prestice Black-Pied (PC) pig breed (Czech national breed and genetic resource) and to evaluate possible presence of recent bottleneck in this closed small pig population. One hundred and eighty of breeding boars were analysed by eleven tetramer Short Tandem Repeats (STR) panel specifically developed for the genotyping of breeding livestock. Despite the fact that appearance of rare alleles, which may be relatively increased after recent bottleneck, was discovered, the heterozygosity excess was not significant. The PC breed has not undergone recent bottleneck and remained at mutation-drift equilibrium.
