Lameness is one of the most common problems in show pigs. Deficiencies of choline, methionine, and thiamine in the sow’s diet may precipitate the syndrome, and zearalanone toxicity via the sow’s milk has been implicated, but there is controversy as to the exact cause. Lameness in pigs is a major health problem on commercial pig farms and is an area of growing concern. Infection with M hyorhinis usually results in lameness with moderate morbidity and low mortality, but H parasuis can cause infection in 50%–75% of pigs and mortality of up to 10%. lameness.
