Interpretive Summary:

Technical Abstract: Amino acids are involved in many important physiological processes affecting the production, health, and reproduction of high-producing dairy cows. Most research and recommendations for lactating dairy cows has focused on methionine and lysine for increasing milk protein yield. This is because these amino acids have been shown to be co-limiting or first-limiting for milk protein production under a variety of nutritional conditions. More research is needed to define the requirements for other essential amino acids for milk protein production and especially for functionality in health and reproduction. Existing information on these subjects will be reviewed with discussion focusing on emerging concepts in amino acid nutrition, functionality, and balancing.
