Methiosol-880 Oral supplies the animal additional methionine. Methionine is an essential amino acid. Often methionine is one of the first limiting amino acids. This means that without sufficient amounts of methionine in the diet, all other amino acids cannot be used by the animal. Hence, growth will be impaired and feed efficiency will be reduced. Methionine is involved in protein synthesis and also serves as a co-factor in a variety of biochemical reactions through its function as methyl donor. Methionine deficiency will therefore also negatively affect these biochemical reactions. Methiossol-880 Oral is the solution to compensate diets low in methionine.
