Poultry is the most important source of animal protein in the world, and it is also one of the largest users of antibiotics as growth promoters.Medicinal properties of Allium sativum (Garlic) have been recognised since ancient times. The emergence of multi-drug resistant diseases in poultry is linked to antibiotic use in poultry feed. Therefore,garlic as a feed additive can enhance poultry production. Organosulfur compounds, polyphenols, saponins, fructans, and fructooligosaccharides are some of the bioactive chemicals found in garlic, which have shown proven physiological effects in poultry such as antioxidant, antibacterial, antiviral, immunostimulatory, intestinal homeostasis, and cholesterol-lowering activities. This article highlights the beneficial applications of garlic as a feed additive in poultry, its effects on growth performance, illness prevention, gastrointestinal and immunological regulation for safeguarding health of birds.
