Why is it measured?
Leg swellings are caused by an inadequate environment and are associated with poor flooring conditions. Bursitis, a specific form of leg swelling, is associated with trauma which may arise from wet, slippery or damaged floors and is much less prevalent in systems with sufficient bedding. Leg swellings may be associated with abnormal posture, locomotion and foot lesions of the hind limb and therefore have a detrimental effect on pig welfare.
How to assess and score using the AssureWel measure
