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