The present review was compiled to reveal the immunomodulatory effects of Allium sativum (garlic) in poultry. The complex therapeutic property of garlic extract makes it one of the most promising phytobiotic used in poultry and other animal species. Garlic contains various organosulfur compounds include alliin, diallyl disulphide, (E-Z) ajoene compounds and dithiane. The aged ethanolic extract of garlic contains S-allylmercaptocysteine (SAM-C) and S-allyl-L-cysteine (SAC). These compounds have different medicinal properties which regulate the immune system, hypercholesterolaemia, growth rate, feed intake and feed conversion ratio among these therapeutic properties, immunomodulation is the key point of this review, due to the high residual effect of antibiotics in poultry and its byproducts. Garlic showed significant immunomodulatory activity by stimulating the proliferation of lymphocytes, antibody production and transition in cytokines secretion. The extracts of garlic also showed anti-inflammatory activity by downregulation of IL-10 and IL-12 in inflammatory bowel diseases and prevent the binding of IL-12 to its receptors present in natural killer cells and T cells. The conclusion of this review is that inclusion of garlic in the diet of poultry improves the immune status by stimulating the cells of immune system.
