Howell et Al. reported no detectable antibody to IBDV in 560 sera examined from New Zealand poultry flocks. Between March and August 1985, 1793 sera were collected from meat chicken farms in Auckland, New Plymouth, Levin and Christchurch. A minimum of 20 birds were sampled per flock. Of the 1793 sera samples collected, 1553 were tested in our own laboratory for the presence of antibody to IBDV using an agar gel precipitin (AGP) test system. Inactivated IBDV antigen and positive and negative sera controls were supplied commercially. Sera from 240 sampled birds was sent to Ross Breeders Veterinary Laboratory, Midlothian, Scotland, to be tested for the presence of IBDV antibody. The results of all sera tested…
