Abstract: The present experiment was conducted to study the biological effect of phytogenic growth promoter supplemented with the diet or added in the drinking water in the broiler birds. In the experiment, two proven phytogenic growth promoters, Digestarom 1317 (dosage 150 ppm) and Digestarom 1440 (dosage 800 ppm) AC were fed to the broiler chickens against an antibiotic growth promoter, Bacitracin Methylene Disalicylate (BMD). The experimental birds were distributed into four equal groups viz., T1, T2, T3 and T4. Birds of the negative control group (T1) were supplemented with basal diet but no growth promoter and birds of the positive control group (T2) were supplemented with basal diet with BMD. Birds of T3 and T4 groups were supplemented basal diet along with two different doses of phytogenic feed additive, Digestarom 1317 @ 150 ppm and Digestarom 1440 @ 800 ppm. Studies on different biological parameters revealed that phytogenic growth promoters significantly (P<0.001) enhance the productive performance of treatment group.
