Methionine and amino acid profiling

The full amino acid and energy profile sets the starting point for a methionine decision. The discussion considers how formulation, digestible supply, rumen protection, production stage, intake, and forage quality influence the question. Methionine may be limiting in some diets, but the assumption should be tested with the selected model and farm data. Transition-cow considerations include intake, body condition, health events, and milk response. Record the baseline and define the target before interpreting a change in the ration.
