Due to over bacterial resistance as well as ban of antibiotic growth promoters (AGP) in the European countries many alternative substances have been investigated for their potential to replace AGPs. Phytogenic products are also called phytobiotics or biologicals. Phytogenic products are one of the promising alternatives due to their high content of pharmacologically active compounds. There are various in vitro and in vivo studies have confirmed a wide range of activities in terms of phytobiotics in poultry and pig nutrition, gut health and management like stimulation of feed intake, antimicrobial, coccidiostatic and anthelmintic effects. The use of antibiotics and other allopathic as well as homeopathic medicines reduced day by day. This trends are observed due to people are more health conscious about the side defects, quality of food, cost of production, poultry health and welfare is an ever-growing demand for low-priced, high quality food, improved feed hygiene, greater poultry health and welfare, and reduced environmental health hazards. Now days, Researcher has focused more on the development of alternative strategies to maintain poultry and pig health and enhance performance with numerous natural substances, termed as natural growth promoters (NGPs) have been identified as effective alternatives to antibiotics. Phytogenic products or phytobiotics are natural growth promoters that have been growing in popularity as feed additives, due to their beneficial effect on gut health and immunity and growth performance along with no residual or side defect on meat and egg qualities.
