Mycoplasma hyosynoviae (M. hyosynoviae) bacteria cause respiratory disease and lameness in pigs, contributing to economic loss and decreased animal welfare, and is a major driver of antibiotic use in swine production. Little is known about the incidence and causes of lameness in swine. This research is identifying factors that cause swine lameness to determine whether management factors like floor type, pen size and nutrition underlie common lameness problems. If lameness is caused by non-bacterial factors like M. hyosynoviae, alternative methods of prevention can be identified, reducing antibiotic usage.
