Footrot is the leading cause of lameness in sheep worldwide, causing significant pain and production loss; effective prevention and treatment protocols are well established.
Footrot causes severe inflammation and tissue necrosis between the claws, producing a characteristic offensive odor. Affected sheep bear minimal weight on infected feet and may graze on their knees. The pain significantly reduces time at pasture, feed intake, and in ewes, milk production for lambs. Lameness scoring and prompt treatment are critical welfare interventions. Chronic untreated cases lead to permanent hoof deformity and persistent pain. Eradication programs using vaccination have achieved footrot-free flock status for some producers.
