CONCLUSION
In conclusion, the results of this study suggest that interaction between feed physical form and feed restriction systems significantly improved live body weights, weight gains, and feed efficiency at starter, grower and whole experimental periods. Feed restriction significantly reduced feed consumption and abdominal fat without any side effects on carcass traits and digestive organs. However, more detailed studies are still needed to determine the optimal particle size and the mode of action of these feed physical forms to achieve the optimal growth performance, nutrient utilization and gut health in broiler production.
