Two commercial breeder chicken flocks of 120 day old were vaccinated by inactivated oil emulsion NDV. The first flock was inoculated with LaSota stain vaccine every 30 days and the other flock was inoculated with the same vaccine every 50 days for 9 successive vaccinations. The first flock recorded high immune response and egg production levels than the other flock.
