Preventive and therapeutic effects of egg yolk antibody, immunoglobulin Y (IgY), against canine parvovirus (CPV) was evaluated in 25 pups orally challenged with CPV-2a. Oral administration of IgY using powder, paste and coated paste delivery systems was compared. Each type of IgY was administered orally for 17 days from 3 days before challenge. The group of pups administered coated IgY showed mild symptoms such as a moderate decrease in total white blood cell count, no depression, vomiting and diarrhea when compared with other groups. The overall clinical score of the group of pups administered coated IgY was significantly lower than that of the challenge control group. However, mortality did not differ among groups because not all pups received symptomatic treatment. These results implied that oral treatment of coated IgY could improve therapeutic effects against CPV challenge if pups received symptomatic treatment.
