Abstract

A 5-year-old Holstein-Friesian cow which had previously given birth to 2 normal calves was delivered of a stillborn anomalous female calf weighing 27kg after prolonged gestation (372 days). Anencephaly, anophthalmia, persistent truncus arteriosus, duodenal atresia of the blind-end type and many other defects were observed. Pathogenesis of these abnormalities was briefly discussed from an embryological point of view. This was a rather rare case of anencephaly associated with several defects.
