Abstract
ABSTRACT The present study was conducted to evaluate the effects of supplementation of garlic, ginger in the diets of broiler chickens and assessment in terms of feed intake, growth performance and economics of feeding. The results showed that groups supplemented with 0.5% garlic powder and 0.5% ginger powder has shown significant effects on body weight as compared to the control group at day 28. Groups supplemented with 0.5% garlic powder and 0.5% ginger powder show significant increase in body weight than the groups supplemented with 0.25% garlic powder and 0.25% ginger powder. Between different supplemented groups, villus length and width of duodenum and jejunum of birds served with 0.5% garlic powder and 0.5% ginger powder is significantly higher than the villus length and width of birds supplemented with 0.25% garlic and 0.25% ginger powder. Between different supplemented groups, villus length of ileum of the group supplemented with 0.5% garlic powder is significantly (p<0.05) lower than the villus length of the groups supplemented with 0.25% garlic powder and 0.25% ginger powder.
