General information
L-methionine is one of the eight essential amino acids which come from food and are not synthesized in the body.
Appearance
White crystalline powder with specific odor
Biological effects
Methionine as an essential amino acid which plays an important role in metabolism. It is actively involved in the synthesis of tissue proteins, a number of vitamins, hormones, and enzymes, due to the presence of a loosely-bound methyl group (-CH3) which can pass to DNA and is a versatile source of methyl groups for all nucleic acids. Furthermore, methionine affects hemoglobin synthesis directly, is required for the synthesis of adrenaline, norepinephrine, cyanocobalamin, creatinine, nicotinic acid amide, and of a number of other substances that have effects on nitrogen, carbon and fat metabolism. Along with cystine and vitamin A, it is involved in the formation of bird feathers, and prevents fatty liver in complex with cystine and vitamin E.
Followed by the lack of methionine, the loss of appetite, anemia, muscle atrophy, fatty liver, renal dysfunction, decreased fertility, growth retardation in younger generations and decreased productivity in adult poultry, feathering disturbances (ruffled feathers, feather dullness, fragility, and loss) are observed.
All the above cause low efficiency of feed utilization. Formation of egg- white and, consequently, egg weight are reduced.
Disturbances of lipid metabolism characterized by fatty infiltration and degeneration of the liver are observed.
Followed by lack of vitamin E, methionine deficiency leads to muscular dystrophy and in leg dermatitis in chickens.
Safety measures
Unloading, storage and loading of feed DL-methionine should be performed in compliance with the general safety measures provided for handling chemicals. In cases of potential contact with the skin or eyes, protective equipment (rubber or plastic gloves, goggles) should be used. Hands and face should be washed before working breaks and after work. In case of contact with eyes, rinse eyes with plenty of water.
Storage conditions
