Influence of MHS genetic status of boars on fertility of sows and production traits of piglets

The research aim was to determine influence of MHS gene polymorphism on the most important slaughter and production traits of pigs. For the purpose of carrying out the research, semen of 6 Pietrain boars of different MHS genetic status was used for insemination of 120 Large White and German Landrace sows crossbreds. Fertility and production traits were monitored during rearing and fattening period of offspring. Upon completion of fattening and slaughtering, the slaughter traits of pig carcasses and meat were determined. The results proved that sows inseminated by boars carrying MHS gene had weaker fertility, and their piglets grew slower during sucking period and rearing. As for the production traits during fattening, there were no significant differences determined between the investigated pig groups. Values of slaughter traits obtained on pig carcasses and meat pointed out the necessity of excluding carriers of MHS gene from production because of their unfavourable influence on carcass and meat quality.
