Effect of so-called chicken anemia agent maternal antibody on chick serologic conversion to viruses in the field.
Chicken anemia agent (CAA)-antibody-positive and -negative broiler chicks and specific-pathogen-free chicks were confined in six broiler houses. Data on seroconversion to common avian pathogens and production performance were collected. No significant differences were seen between CAA-antibody-positive and -negative chickens in geometric mean antibody titers against common avian pathogens or in production performance.
