The sustainability benefits of amino acid utilization are equally compelling. By enabling substantial reductions in dietary crude protein while maintaining or improving performance, these nutrients dramatically decrease nitrogen excretion and its associated environmental consequences. This nutritional strategy aligns perfectly with circular economy principles, transforming feed inputs more efficiently into high-quality animal protein with minimal waste. As global standards for responsible production continue to evolve, amino acid supplementation emerges as a key technology for meeting both regulatory requirements and consumer expectations for sustainable protein production.
