Abstract

The pedigree analysis of the local endangered Přeštice Black-Pied pig breed (n=19 289) was performed. Animals born within the period 2012-2014 were assu­med as the reference population (n=1 374). The pedigree completeness index rea­ched 100% for four generations back. The 100 % of the genetic pool was explained by 66 ancestors. Although all animals of the reference population were inbred, 57% of them had inbreeding less than five percent. Average inbreeding, co-ancestry coefficient and rate of inbreeding reached 4.93%, 13.48% and 1.29% in reference population, respectively. The effective population size calculated by four different methods varied from 32 to 91 animals in 2014. Average generation interval, avera­ge family size for sire and dam parents was 2.5, 17.46 and 6.5 animals, respecti­vely. Total number of founders, effective number of founders, effective number of founders’ genomes and effective number of non-founders genomes reached values 299, 98.05, 21.92 and 28.23 founders, respectively. The average genetic diversity (GD) loss was 13.71% in reference population. The GD loss has increased within the last three year period mainly due to the random genetic drift (77.6%) and by unequal contribution of founders (22.4%). The Přeštice Black-Pied breed is highly endangered with GD loss. Mating of closely related animals has to be prevented in breeding and mating program of this breed.
