Congenital deformities in the sudan 4. Wry face in a cross-bred bovine calf [electronic resource].

Includes references.

A description is given to a cross-bred female calf with congenital deformities in the head region. The animal had wry face, microphthalmia, dermoid cysts in both eyes and a characteristic circling movement. A mass of tissue was almost occluding the left nostril. The post-mortem examination of the trunk that was performed immediately after severing revealed petechial haemorrhages in lungs, hypertrophied yellowish liver and greenish yellow discoloration of the body fluids. No apparent internal anatomical deviations were observed. The histopathological examinations revealed multi-focal haemorrhages in the lungs and hyperplastic connective tissues, bile ducts proliferation and slight inflammatory cells infiltration in the liver. The nasal tissue mass was found to be a mass of hyperplastic muscle and connective tissue fibres.
