Lame boars had lower bone mineral density and bone marker scores. With age, bone mineral density increased, and keeping boars in individual stalls affected the deterioration of these indicators. The concentration of calcium and phosphorus in the blood serum also affected bone mineral density. Bone mineral density may be a useful tool for predicting lameness.
