摘要
2024年肉鸡能量、蛋白质和氨基酸营养研究聚焦于精准营养调控与可持续发展,旨在优化饲料效率、生产性能及肠道健康。研究表明,肉鸡能量需求受遗传、生长阶段、环境及饲料组成等多因素影响,合理调整能量水平可显著改善生长性能与饲料转化率。低蛋白日粮技术持续发展,通过氨基酸平衡与合成氨基酸补充,在降低氮排放的同时维持生产性能,其中赖氨酸、蛋氨酸等必需氨基酸的精准供给是关键。功能性氨基酸在免疫调节与肠道健康中的作用被深入探讨,其与肠道微生物的互作机制成为研究热点。
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.
