This review paper was designed with the objectives of revising information on feed additives in poultry production. Poultry feed consists of a range of substances known as “feed additives”. It has non-nutritive substances usually added in amounts of less than 0.05 percent to maintain health status, uniformity and production efficiency in intensive production systems. These additives have now become vital components of practical diets. The use of harmless and new natural feed additives is an active means of correcting dysbacteriosis, normalizing microbiological processes in the digestive tract, increasing the growth rate and efficiency of young poultry by refining the digestibility and use of nutrients in the diet, reducing feed costs per unit of growth. In some cases Feed acidifiers are added to the feed to lower the pH of the feed and consequently the gut environment. Also Antimicrobials have been used extensively in intensive poultry operations to minimize disease and improve growth and feed utilization. This review recommended further studies will be crucial, verifying mainly the efficacy of feed additives, their safety with regard to animal health and wellbeing, the quality of animal.
