The present experiment was conducted to know the influence of double vaccination of New Castle disease vaccine (inactivated) and fowl pox vaccine (avianized pigeon pox virus) on broiler chick.White Cornish male cross Barred Plymouth Rock female chicks were devided in three experimental groups. All chicks were vaccinated with fowl pox vaccine at hatched time. The 1st group was the control group and did not receive any other vaccine. The 2nd and 3rd groups were vaccinated simultaneously with New Castle disease vaccine and fowl pox vaccine at 3 and 21 days old. All groups were fed with commercial broiler feed and only the 3rd group was fed with the medicated feed for 6 days at the vaccinations. The medicated feed included 220mg of chlortetracycline in 1kg feed, 0.3% of terephtalic acid and 0.2% of commercial vitamin mixture for chick.No influence was observed on body weight gain, feed intake, feed requirement and mortality in 10 weeks.
