چکیده

Restriction on the use of in-feed antibiotics in many countries has fueled the interest in alternative products. A group of natural products known as phytogenic has been the focus of several studies in recent years Phytogenic feed additives, known as PFAs or botanicals, are substances of plant origin added to animal diets at recommended levels with the aim of improving animal performance. Essential oils, herbs and spices all serve as sources for bioactive ingredients, e.g. phenols and flavonoids. In poultry, the effects of antibiotics on growth and overall health of the bird is debated. Past research has shown that antibiotic growth promoters have increased feed intake and growth of livestock birds, however, most noticeable is the effect on feed efficiency. Studies for this reason, focused on the interaction between antibiotics and the natural microflora of the gut as well as the reduction of pathogens leading to infection within the bird. Given that antibiotic resistance is a concern for both the poultry industry and issues of human health, research has become focused on finding alternatives to antibiotics. Such alternatives include are prebiotics, probiotics, enzymes and phytogenic based feed additives. This review is a brief overview of the effects of phytogenic additives on broilers
