DL-methionine feed is a crystalline powder additive that has a pungent odor. Active substances in the composition of the drug - 99%. They are represented by D- and L-isomers of alpha-amino-gamma-methylthiobutyric acid.
The amino acid that the drug contains promotes proper metabolism in the body. The presence of a methyl group (CH3) in methionine makes it possible to synthesize protein tissues and vitamins, hormones and enzymes. The drug is active in the synthesis of hemoglobin, without which adrenaline, creatinine, and norepinephrine cannot be produced. These are the main components of the proper metabolism of carbons, fats and nitrogen. Methionine, in combination with cystine, with the participation of vitamin A, promotes the formation of feathery covering in birds. Cystine, together with vitamin E and methionine, prevent liver degeneration.
DL-methionine feed, used in powder form, is absorbed by the body almost three times more efficiently than the same drug in liquid form. A lack of substances contained in DL - methionine leads to decreased appetite, muscle atrophy, anemia, and fatty liver. As a result, productivity and weight gain drop sharply.
In birds, the feather covering becomes brittle, ruffled, and colorless. Egg white production slows down, and productivity decreases accordingly. In addition, if there is a lack of vitamin E in the feed, the bird will develop dermatitis and muscle dystrophy.
The drug mixes well with feed, so its use is quite effective. Methionine is safe for equipment - it does not cause damage to metal parts of equipment in feed mills.
Feed DL-methionine is used to enrich feed, premixes, and mixtures with useful additives in the preparation of diets for animals (poultry). The drug is dosed based on age, type, and conditions of detention. On April 30, 1997, the Ministry of Agriculture of Russia approved the Standards “On the use of biologically active substances (BAS) and the norms for their introduction into mixed feed,” regulating the amount of the drug administered.
