This study was carried out to produce IgY against B. bronchiseptica, parvovirus and distemper virus that are major pathogens in alimentary and/or respiratory diseases of dogs. In the comparison of adjuvants, ISA70 was the best in the rapid induction and maintence of antibody titers. Agglutination antibody titers against B. bronchiseptica were 1:1,280~1:10,240 in sera and 1:160~1:1,280 in egg yolk. Hemagglutination inhibition(HI) titers against parvovirus in sera and egg yolk were 1:80~1:320 and 1:64~1:256, respectively. Virus neutralization titers against canine distemper was 1:8~1:64 in sera and egg yolk.
