This Good Practice (GP) focuses on improving broiler productivity and environmental sustainability by reducing crude protein levels in diets while maintaining an optimal balance of essential amino acids. By aligning nutrient supply more closely with the birds’ physiological needs and supporting gut health through targeted additives, the practice enhances feed efficiency, reduces nitrogen waste, and promotes overall well-being. Implemented through precision diet formulation and integrated management strategies, it enables farms to improve performance while lowering their environmental footprint.
