Poultry industry is currently transforming towards decreased use of Antibiotic Growth Promoters (AGPs) due to increased concerns regarding development of antibiotic resistant bacteria and transfer of residues of AGPs in meat and eggs. Phytogenic additives being natural, non-toxic, residue free and their easy availability make them first choice as alternate to AGPs in poultry production. Ajwain (Trachyspermum ammi also called Carum copticum, Trachyspermum copticum) is a medicinal plant that belongs to family Apiaceae. Ajwain seeds are used extensively for medicinal purposes as a digestive stimulant and to treat liver disorders. Ajwain is highly esteemed as a remedial agent for flatulence, flatulent colic, atonic dyspepsia, diarrhoea and in short, as a digestive aid and as an antiseptic. Medicinal properties of the plant include antioxidant, antispasmodic, antimicrobial and antifungal activity. The present study indicated that inclusion of ajwain powder at 0.25% in the diet resulted in decreased feed cost / kg gain and increased digestibility of nutrients in quails.
