Commercial broiler is one of the fastest growing birds, its growth and development are a dynamic processes.Presently a need has arisen to completely avoid usage of antibiotics in poultry feeding due to increasing consumer concern for poultry drug residues in meat and egg. Hence, an alternative to antibiotics like probiotics, prebiotics, synbiotics and phytobiotics are being tried in poultry rations to improve growth, productivity and immunity against diseases. In this connection, phytobiotic such as, garlic (Allium sativum) and nilavembu (Andrographis paniculata) could be used as an alternative. The combination of these two phytobiotics have definitely brought about synergistic effect on the production and enhanced immunity in broilers.
