A genetic trend in a herd of pigs of farmbreeding type «Bagachansky» of the Large White breed

Abstract

During 2002–2010 the estimation of breeding (genetic) value of
pigs of farmbreeding type «Bagachansky» of the Large White
breed was conducted by BLUP method. On the basis of obtained data the genetic trend in a population for basic productive
traits was characterized. It was established that the phenotypic
estimation of high heritability traits vary proportionately with
genetic trend. There are also some differences, for example, the
animals of a foreign selection which were used in 2004 could
not show up their genetic potential because of housing conditions and feeding.
