ABSTRACT.- In a beef cattle breeding farm located in northern Uruguay, an Aberdeen Angus calf was born with complex anomalies. The offspring was sired by one of the bulls of the farm. The calf died shortly after birth, displaying multiple malformations at external examination, including agenesis of the lumbar, sacral and coccygeal vertebrae and spinal cord and arthrogryposis of both pelvic limbs, characteristic of perosomus elumbis (PE).
