Abstract

Seven cases of hydranencephaly and cerebellar hypoplasia in a water buffalo herd are described. The herd of 133 females was divided for mating into 4 groups and mated with different bulls. The disease was observed in the offspring of 5 cows from only 1 group over a period of 6 years. These cows had all mated with the same bull during that period. All affected calves were unable to suckle, showed intention tremors, involuntary movements of the ears, depression, and blindness. Some calves were recumbent and others showed wide-based stance and inability to walk. At necropsy, all affected calves had similar lesions consisting of hydranencephaly and cerebellar hypoplasia. Histologically, the cavities were surrounded by normal-looking nervous tissue. The occurrence of the disease in the offspring of only 1 out of 6 bulls in different years, the similar lesions in all 7 calves affected, and the negative serology and immunohistochemistry for Bovine virus diarrhea virus and Bluetongue virus highly suggest that the disease is hereditary.
