During two years, the occurrence of heart damage - foramen ovale patens, and the main characteristics of fattening capacity and carcass values were investigated in Large White, Landrace, Pietrain, Duroc, Yorkshire and Slovac Meat pig breeds. The occurrence of foramen ovale patens was different in the individual breeds observed, the highest values being found in the Large White breed (15%) and the lowest in the Yorkshire breed (2.7%). In Pietrain and Duroc pigs the existence of this type of heart damage was not detected. Concerning fattening capacity markers and carcass values, the highest daily weight increase was found in the Yorkshire breed and the lowest in the Pietrain breed. Maximal length of trunk was observed in the Landrace breed. The greatest area of Muscuus longissimus dorsi, as well as weight of thigh meat (%) was noticed in the Pietrain breed. Maximal values of thickness of backfat were found in Large White pigs and minimal in Pietrain and Duroc breeds. Complex analysis of the results indicated, that the presence of foramen ovale patens had a negative influence on the main parameters of fattening capacity and carcass values of pigs.
