Cows have a protein requirement for growth, maintenance, and lactation. In order to meet those protein requirements, dairy farmers can supplement or feed cattle with specific amino acids, the building blocks that make-up protein. However, in order for the amino acid product to be effective it must avoid degradation in the rumen and be delivered in the small intestine for absorption. Lysine and methionine have traditionally been recognized as the most limiting amino acids for lactating dairy cows. Therefore, nutrition companies have focused on finding ways to encapsulate or protect lysine and methionine from rumen microbes. The N-acetyl-L-methionine and N-acetyl-L-lysine …
