Usage: DL-Methionine Feed Grade is approved for use in all animal species.Particularly for use in monogastrics,it ensures the adequate supply of sulfur amino acids,especially of the essential methionine. Because of methionine being first-limiting in typical poultry diets,its use has been well established for many years.Additionally,diets for piglets and growing pigs can show a considerable deficiency in methionine,especially when fomulated to achieve low nitrogen excretion for ecological reasons.Such a deficiency can be conveniently compensated for by using DL-Methionine Feed Grade.
Package and Storage: DL-Methionine Feed Grade should be handled in accordance with the Material Safety Data Sheet.Minimize eye and skin contact to protect against irritation. DL-Methionine is packed in 25kg craft paper bag,with labels required by customers.
Shelf life: . Five years
Key words: DL-Methionine , DL-Metionina ,DL-2-Amino-4-(methylthio)butyric acid; Acimetion
