Experiment animal: 1-day-age AA broiler
Experiment design:
Control group (CG): Basal diet
Experience groupⅠ(EGⅠ): Basal diet+100g/t Monensin
Experience groupⅡ(EGⅡ): Basal diet+100g/t Garlic Allicin
1500 AA broilers were randomly divided into 3 groups, each group of 5 replicates, and each repeat 100.

Add garlic allicin and monensin could improve the production performance of broilers; late show the daily gain, feed conversion ratio is reduced. 21 - 42 days - age, EGⅠand EGⅡ weight increased by 2.15% and 2.15% compared with the control, feed conversion ratio decreased by 1.69% and 2.26% respectively; The daily gain increased by 1.62% and 1.50%, feed conversion rate decreased by 1.23%.There was no difference between groups. Garlic allicin and monensin can improve poultry production performance.
Tab.3 Effect of allicin on the survival rate of broiler

EGⅡsurvival rate is higher than EGⅠ.
Garlic allicin contains natural antiseptic, metabolism in animals to prototype, non-toxic, no side effect, no drug residues, and no drug resistance. The experimental results show that in the diet the amount of adding garlic allicin is similar to that of antibiotics, can improve the production performance of broilers.
