Poultry is widely produced and consumed meat globally.Its demand is expected to continue increasing to meet the animal protein requirement for ever-increasing human population.Thus,the challenge that poultry scientists and industry face are to produce sufficient amount of poultry meat in the most efficient way.In the past,using antibiotics to promote the growth of poultry and manage gut microbiota was a norm.However,due to concerns over potential fatalistic impacts on food animals and indirectly to humans,their use as feed additives are banned or regulated in several jurisdictions.In this changed context,several alternative strategies have been proposed with some success that mimics the functions of antibiotics as growth promoters and modulate gut microbiota for their beneficial roles.These include the use of probiotics,prebiotics,organic acids,and exogenous enzyme,among others.Gut microbiota and their metabolic products improve nutrient digestion,absorption,metabolism,and overall health and growth performance of poultry.This paper reviews the available information on the effect of feed additives used to modulate intestinal microbiota of poultry and their effects on overall health and growth performance.Understanding these functions and interactions will help to develop new dietary and managerial strategies that will ultimately lead to enhanced feed utilization and improved growth performance of poultry.This review will help future researchers and industry to identify alternative feed ingredients having properties like prebiotics,probiotics,organic acids,and exogenous enzymes.
