Interpretive Summary:

Technical Abstract: Dairy cow protein and amino acid nutrition have a significant role in sustainable dairying. Protein, amino acids, and nitrogen are inextricably linked through effects in the rumen, metabolism of the cow, and environmental nutrient management. Feeding systems have been making progress toward emphasizing the requirement of amino acid nutrition for the cow while optimizing microbial protein synthesis. Opportunity exists to make further improvements in understanding and predicting the protein and amino acid nutrition of the cow. This chapter will review the current state of knowledge of protein and amino acid nutrition for application in large dairy herds. Emphasized areas are feed protein sources and evaluation methods, rumen metabolism, the nutrition of the cow, and practical management strategies.
