In layman’s terms,what does EAA mean?
Essential amino acids (EAAs) are the amino acids that need to be supplemented in the dairy diet. Dairy cows cannot synthesize enough of these amino acids to maintain their body functions at peak levels.
Most dairy nutritionists report that they balance the amino acid levels in their dairy rations to bolster income over feed cost (IOFC). Typically, this includes the use of supplemental methionine and lysine, the first two limiting amino acids.
They are limiting because, when in short supply, they can limit herd performance. Supplementation is required as they do not naturally occur in high enough levels in feedstuffs to meet dairy cow needs.
