Since the EU banned antibiotic growth promoters (AGPs) in poultry nutrition, many researches has been conducted to explore the use of possible effective substitutes. Prebiotic products are incorporated in poultry feed to replace AGPs in order to stimulate or promote the effective use of feed nutrients which may subsequently result in more higher production rates and improved feed efficiency and induce the growth and activity of beneficial microorganism. Moreover, prebiotic may improve digestion and stimulate the immune system in poultry. Consequently, several researches were performed to confirm their beneficial qualities. Productive performance that were dominantly observed and analyzed are feed intake, body weight gain and feed conversion ratio. Most of the trials showed slight positive effects, however significant results were rare. Since there are almost unlimited possibilities concerning dosage and products of prebiotic there is still more research needed. Therefore, it is necessary to define and declare the composition of prebiotic used in experiments. Generally, it can be stated that prebiotic have the potential to be considered as an alternative to AGPs in poultry nutrition. Nevertheless, there is still further research under more standardized condition needed to evaluate the right dosage and the exact mechanism of actions.
