Evaluation of Comparative Effect of Feed Additive of Allium Sativum and Zingeber Officinale on Bird Growth and Histomorphometric Characteristics of Small Intestine in Broilers

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.

摘要 本试验旨在评估日粮中添加大蒜、生姜对肉仔鸡的影响，并从采食量、生长性能及饲喂经济效益三个维度进行评价。结果显示，在第28日龄时，日粮添加0.5%大蒜粉与0.5%生姜粉的试验组，其肉仔鸡体重相较于对照组具有显著改善效果。添加0.5%大蒜粉与0.5%生姜粉的试验组，其肉仔鸡体重显著高于添加0.25%大蒜粉与0.25%生姜粉的试验组。各试验组间，饲喂0.5%大蒜粉与0.5%生姜粉的肉仔鸡，其十二指肠、空肠的绒毛长度与宽度均显著高于饲喂0.25%大蒜粉与0.25%生姜粉的试验组。各试验组间，仅添加0.5%大蒜粉的试验组，其肉仔鸡回肠绒毛长度显著（p<0.05）低于添加0.25%大蒜粉与0.25%生姜粉的试验组。
