OSTEOCHONDROSIS IN WILD BOAR SWEDISH YORKSHIRE CROSSBRED PIGS (F2 GENERATION)

Osteochondrotic lesions occur in very high frequency in growing pigs o f all commercial breeds and are claimed to be associated with high gro wth rate, and not to occur, or to be milder, in slow-growing pigs. The present study monitored the magnitude and distribution of osteochondr otic lesions in a crossbred pig population of wild boar and Swedish Yo rkshire ancestry. In this population, having a low growth rate, the di stribution and extent of osteochondrotic lesions was similar to that o f purebred Swedish Yorkshire pigs, and only weak relationships between the studied growth parameters and osteochondrosis could be found.
