crooked calf

crooked calf

a syndrome of arthrogryposis and/or cleft palate occurring in regions of western USA and Canada. Arthrogryposis varies in severity from calves that are ambulatory and may achieve market status to those that are severely deformed, requiring cesarian section or destruction. Cleft palate is usually fatal. In endemic areas, it has constant but low prevalence with higher incidence and severity periodically. See also lupine-induced arthrogryposis.
