Laminitis in Feedlot Calves

Several severe lameness outbreaks have been seen this winter. High numbers of calves are affected. Problems include subsolar abscesses, toe abscesses, separation of hoof wall from the sole, and infected feet (joints and flexor tendons).

Laminitis is suspected as the underlying cause of the problems. Severe cold and winds cause cattle to back off of feed. When cattle return to eating when the weather moderates, they may get laminitis from increased grain consumption
