Congenital abnormalities are known to occur occasionally in man and farm livestock, and frequently in laboratory animals subjected to certain types of experimentation. A high percentage of the cases are fatal to the young depending on the nature and severity of the complications. In many instances death of the affected young occurs during pregnancy or parturition. Should the feti survive parturition death usually follows shortly thereafter. Extended survival occurs in a small percentage of young and these are mildly to severely handicapped in one or more of a multiplicity of ways. There are many causes of congenital abnormalities. Some are manifestations of disturbances to the germ plasm, while others are strictly somatic. In this report we are concerned with what might be termed disturbances to biochemical mechanisms of embryonic development induced by faulty nutrition. When essential nutrients are either absent from the ration or present in critically insufficient amounts, mild to severe disturbances usually occur to the feti during embryonic development.
