Abstract: This paper reports the diagnosis and spread of bovine viral diarrhoea (BVD) in cattle on the east coast of the North Island. The suspected origin, difficulty in diagnosis, and the spread are discussed from the practitioner`s viewpoint. A mucosal disease-like condition was first reported by Olafsen and McCallum (1946) in cattle and as a neonatal disease by Romvary (1965). The presence of BVD was first identified in New Zealand serologically by Fastier and Hansen (1966), and Robinson (1971) found serological evidence of it in South Island sheep and cattle. Clinical diagnosis was made by Jolly et al (1967) and a virus was isolated. Present methods of diagnosis include clinical observation, post-mortem findings, and changes in titres to serum neutralization tests. Blood (1967) summarized field procedures for the differential diagnosis of mucosal disease in cattle, and at a seminar in Gisborne in 1974 Snowdon and Horner emphasized the wide variety oif clinical entities associated with this virus.
