**9. Conclusion**

The studies discussed above indicate that probiotics may play a significant role in sustainable poultry farming. In all likelihood, they will serve as the superior replacement for antibiotics in poultry industries. Significant work and studies have proved that probiotics help in maintaining health status in poultry animals as they improve gut conditions and enhance nutrient absorption, thus overall improving the growth performance. Probiotics provide protective effect against stress conditions by enhancing antioxidant potential of enzymes. Probiotics also modulate immune response and provide protecting against infections through various mechanism of action. In future, probiotics in poultry feed should continue to determine the optimal conditions and standard methodology under which their application will have the greatest possible beneficial impact on meat quality. Additionally, more clinical trials may be conducted to investigate other potential areas of benefit.
