Protein efficiency in dairy diets

Sustainable dairy nutrition asks how protein moves through the herd and where losses occur. The discussion considers precision formulation, essential nutrient balance, and feed analysis as tools for discussing nitrogen efficiency. Lower crude protein may be appropriate in some rations, but the decision depends on forage, production stage, amino acid supply, manure data, and farm goals. A clear review of intake, milk components, health, and emissions indicators supports better decisions than a single target.
