Tracheal collapse.
Tracheal collapse in calves usually is associated with dystocia at birth, especially breech presentations. Inspiratory dyspnea typically is seen within the first several months of life and may worsen progressively. Lateral cervical radiographs are useful in defining the affected segments as well as identifying previously fractured ribs. Surgical stenting of the trachea will improve the calf's condition, but because this procedure is done on young calves, the tracheal diameter of the affected segment is permanently limited by the size of the prosthesis.
