Sow lameness has been recorded in up to 60% of sows in a herd, and is the second most common reason for culling a sow.  It can be caused by various factors including disease, flooring, or fighting between sows. Currently, the best strategy for managing lameness is to have routine, recorded observations, and to intervene early on. Mild lameness may be treated with NSAIDs, rubber flooring, isolation, and hoof trims. When possible, the cause of lameness should be determined, and sow management re-evaluated if the prevalence is high in young sows.
