Abstract

Pig selection was based on phenotypic manifestation of features in animals and/or their relatives. Molecular and genetic methods for identification and improvement of breeding and selection features take place in intensive production during last decade. In that way, numerous scientific results were implemented in practice to improve production economy. These methods make it possible to identify desirable animals in the early age, even before these economically significant production features have become apparent. With tests for detection of gene code errors concerning specific hereditary diseases these individuals could be eliminated from further breeding. After the fifth release of Pig quantitative trait loci database (QTLdb) at the beginning of 2007, there were 1673 QTL for 281 different breeding traits. At the end of 2007 this number reaches 1809 QTL. The most of them (77%) are traits connected with meat quality, 15% are connected with production features, 4% with reproduction features, 3% of them are connected with exterior and 1% with animals’ health.
