A congenital deformity in calves induced by the maternal consumption of lupin

Abstract

A congenital skeletal deformity called "crooked calf syndrome" occurs in many of the beef cattle-producing areas of the western United States. This deformity is characterized by arthrogryposis, torticollis, scoliosis, and cleft palate. The condition is non-hereditary, and is due to the consumption of lupin by the dam. The most severe and characteristic deformities are produced between the 40th and 70th days of gestation.
