ABSTRACT

Overuse of antibiotics in the poultry industry has negatively impacted global health; therefore, its use has been restricted in many countries to lessen the deleterious effect on food animals. This condition has stimulated the poultry industry to search for innovative feed additives to improve the overall health of animals and be safe for people and the environment. Probiotics are investigated to be one of the propitious solutions to solve the negative issue of antibiotics like antibiotic resistance and suppression of beneficial microbes. Probiotics include living microbes, when ingested, show health benefits. They can improve overall health of the animals by modulating the gut microbiota, treating the number of infections, stimulating immune function, and enhancing overall gut health. Generally, probiotic species include bacteria and some yeast. This paper briefly summarizes the working actions of probiotics and demonstrates the potential impacts of different doses of probiotic species on various parameters of poultry health, including growth performance, morphology, and gut microbiota.
