Brachyspina syndrome in two Holstein calves.

Brachyspina syndrome, a rare lethal skeletal malformation, is described in two Italian Holstein calves. Both calves were stillborn and had shortened trunks with long legs. Radiography demonstrated several abnormalities of the cervical and thoracolumbar vertebral column. Visceral malformations involving the heart, kidney, genital tract and gastrointestinal system were also found. Both calves were traced back to the same sire and an inherited basis was strongly suspected.
