摘要

The last few decades have been marked by a rapid genetic improvement in chicken growth rates.The modern-day chicken is more efficient in converting feed into muscle mass than their predecessors.This enhanced efficiency emanates from better nutrient digestion,absorption,and metabolism.The gut has therefore become a research focus especially after the ban on the use of antibiotics as growth promoters(AGP)in poultry.In pursuance of better gut health in the post-AGP era,many different strategies are being continuously sought and tested.The gut is inhabited by more than 900 bacterial species along with fungi and archaea,and they play an important role to maintain a conducive milieu for the host,A beneficial shift in the microbial ecosystem of the chicken can be promoted by many dietary and nondietary interventions,however,diet is ranked as one of the most important and potent regulators of gut microbiota composition.Therefore,the constituents of the diet warrant special attention in the modulation of the gut ecosystem.Among dietary constituents,fiber possesses a significant ability to modulate the microbiota.In this review,we will highlight the importance of fiber in poultry nutrition and will also discuss the effects of fiber on gut microbiota and its resultant ramifications on the liver and brain.
