Vibriosis in cattle

Abstract

Extract Control of vibriosis in cattle in New Zealand has depended on treatment in acute outbreaks, followed by artificial breeding with semen from non-infected sires. These measures are quite effective where they can be implemented. However, there is a large number of cattle on which the above measures cannot easily be used, namely, beef cattle and dairy cattle in areas where artificial breeding is not practised. At present, this latter category includes approximately 75 per cent of the dairy cattle population of New Zealand. In addition, since there is little possibility in the immediate future of artificial breeding being extended to include beef cattle, other methods of control must be sought. Hence investigations were made into the possibility of prophylaxis by vaccination.
