Abstract Extract Infectious bovine rhinotracheitis (IBR) is an upper respiratory tract disease of cattle producing economic consequences which may range from temporary reduction in milk yield in mild cases, to marked loss in condition and even death in severely affected animals (McKercher et al., 1957 McKercher, D. G., Moulton, J. E., Madin, S. H. and Kendrick, J. W. 1957. Amer. J. vet. Res., 18: 246–246. [Google Scholar]; 1958 McKercher, D. G., Moulton, J. E., Madin, S. H. and Kendrick, J. W. 1957. Amer. J. vet. Res., 18: 246–246. [Google Scholar]). While the mortality rate is low (2 to 10 per cent.), morbidity may be high, particularly under conditions of close herding such as those associated with hand feeding, and in the milking herd.
