SUSTAINABILITY FEED & ADDITIVE MAGAZINE October 2025 67 and processing value. Improving in all cases the cheese efficiency, kilograms of cheese produced per kilogram of milk. • Better animal health: Better nutrient balance strengthens immunity and minimizes metabolic disorders, reducing reliance on antimicrobials. These outcomes contribute to longer productive lifespans and healthier herds, both of which are key pillars of sustainable livestock farming. ECONOMIC BENEFITS AND SOYBEAN SUBSTITUTION Incorporating AA balancing into feed not only reduces emissions but also offers economic gains. In a trial with Lacaune ewes, optimized AA diets led to a 10% cost reduction. This was primarily due to: • Lower total protein inclusion but meeting the metabolizable methionine and lysine needs to reduce feeding costs. • Decreased soybean dependency, mitigating price volatility and offering potential for cheaper, more local ingredients. The strategy aligns perfectly with circular feed systems, which prioritize local, low-footprint ingredients and reduce reliance on imported commodities. CONCLUSION Balancing amino acids through precision nutrition offers dairy farmers a powerful lever to achieve both environmental and economic sustainability. By improving nitrogen efficiency, reducing GHG emissions, and enhancing animal health and productivity, this approach not only meets regulatory demands but also supports long-term profitability. In a sector under intense scrutiny, amino acid balancing presents a science-based, practical solution to future-proof dairy farming — turning sustainability from a cost into a competitive advantage.
