Five different avian and human test strains were applied to 1300 hens of 24 flocks to establish the presence of influenza A antibodies. HI tests were carried out on 2700 blood samples and positive titres and titre movements established. The percentage of birds showing positive reactions was higher in industrialized units than in free-range flocks.
