**8. Limitations on the use of probiotics in poultry**

Because the potential of probiotics supplements varies depending on the species and is not shared between different genera and species of microbes, the widespread adoption of probiotics as part of poultry diets has brought it with some unique difficulties. Furthermore, there is always the possibility that the probiotics will be inadequately handled after they have reached the market, rendering them ineffective. Loss of viability of probiotics may occur when they come into touch with disinfectants in water or other interacting compounds in feed during oral administration. The probiotics' lack of availability until they reach the site of action in the host body is another potential barrier [54].
