Methionine is one of the essential amino acids that cows cannot synthesize and must obtain through feed [Patton, 2010]. It plays a key role in protein synthesis, especially milk protein, and is often one of the first limiting amino acids in dairy cow diets, along with lysine [Schwab et al., 2003]. If methionine is lacking, even with sufficient energy and other nutrients, milk protein production decreases

Methionine is one of the essential amino acids — meaning the calf’s body cannot produce it and it must be supplied through feed. This vital compound plays a key role in muscle growth, protein synthesis, immune system support, and liver function
