Abstract
An outbreak of infectious rhinotracheitis affecting 4 herds of dairy cattle was observed in the Province of Quebec, the general characteristics of which are the same as those reported in the infection of feedlot cattle. However, a 25% average decrease in milk production of affected herds was noticed during the present infection, thus stressing a particular economic aspect. The nature of the viruses isolated during this outbreak and those described previously in North America are identical.
