Abstract: In 2024，the research on the nutrition of energy，protein，and amino acids in broilers focused on precise nutritional regulation and sustainable development， aiming to optimize feed efficiency， production performance，and intestinal health. Studies have shown that the energy requirements of broilers are affected by multiple factors such as genetics，growth stage，environment，and feed composition. Reasonable adjustment of the energy density can significantly improve growth performance and feed conversion rate. The technology of low⁃protein diets continues to develop. Through the balance of amino acids and the supplementation of synthetic amino acids，it can maintain production performance while reducing nitrogen emissions. The precise supply of essential amino acids such as lysine and methionine is the key. The role of functional amino acids in immune regulation and intestinal health has been deeply explored，and the interaction mechanism between them and intestinal microorganisms has become a research hotspot.
