Effect of Either Powder or Encapsulated Form of Garlic and Phyllanthus niruri L. Mixture on Broiler Performances, Intestinal Characteristics and Intestinal Microflora

摘要

Effect of the mixture of garlic and Phyllanthus niruri L. in either powder or encapsulated form on broiler performances, intestinal characteristics and intestinal microflora were investigated. One hundred ninety two 1-day-old Lohmann broiler chicks were subjected to 8 different dietary groups, namely 2 forms of phytobiotic (non-encapsulated powder and encapsulated) and 4 levels of inclusion (0, 0.4, 0.8 and 1.2%). Data were then analyzed by two-way Nested of Completely Randomized Design ANOVA and if there was significant effect followed by Duncans Multiple Range Test. The results showed that combination of garlic and Phyllanthus niruri L. in encapsulated form improved (0.05) BWG and IOFC of broilers, though with almost no changes in intestinal characteristics and intestinal microflora. Increasing levels of garlic and Phyllanthus niruri L. combination from 0 to 1.2% in encapsulated form did not significantly improve broiler performances and intestinal microflora, though they tended to increase (0.01) viscosity. It is concluded that the use of combination of garlic and Phyllanthus niruri L. in encapsulated form performs better than the combination of garlic and Phyllanthus niruri in powder. It is suggested to use 0.8% encapsulated of combination of garlic and Phyllanthus niruri in broiler diet.
