L-Lysine monohydrochloride (99%) favours an intensive assimilation of fodder and promotes an active growth of livestock. Mostly, it is essential for animals, having an unicameral stomach, namely for poultry and pigs. The use of lysine increases the gain in weight of livestock and poultry by 10 to 30%, raises milk yields by 12%, augments egg-laying ability of hens by 10%. Among the amino acids, lysine comes first in all the diets usually applied in the pig breeding. The lysine deficiency in the laying hens of a flock increases the death rate of embryos by 5 to 9%, and in case of broiler chickens, lysine deficiency results in a poor muscle buildup, thus decreasing the quality of meat. 

Major components of raw materials for the production of lysine are: molasses, corn steep, hydrochloric acid, ammoniac water, vitamins, bran, ground sunflower oil-cake, fish meal, meat-bone meal and rape.


Livestock and poultry need lysine for nitrogen and carbohydrate control, and for the synthesis of nucleotides, chromoproteides. Lysine favours also an intensive growth of young animals, an efficient use of fodder, the formation of the melanin pigment in the poultry’s feathering; it exerts an effect on the formation of red blood cells (erythrocytes) and deposition of calcium in the bones. Lysine is also involved in redox reactions and promotes the transamination and deamination of amino acids. It helps to assimilate phosphorus and calcium too. Among the amino acids, lysine comes first in all the diets usually applied in the pig breeding.

Available lysine is more fully used for the synthesis of albumens, which are of particular importance for the formation of skeletal tissue, enzymes and hormones. At the same time, in case of shortage of available carbonhydrates, lysine can be metabolized to obtain glucose and ketonic bodies. This process serves as an important energy source for the organism of a bird during the period of its starvation.

Lysine can be found in all albumens. However, vegetable proteins contain it in insignificant amounts. That’s why, there’s often a lack of it in fodder. A deficit of lysine in the organism can be brought about as a result of feeding the poultry and livestock according to the diets, mainly consisting of cereals, ground sunflower oil-cake and a small amount (1 to 2%) of feedstuffs of animal origin.

L-Lysine monohydrochloride (99%) is a microgranular friable cream-coloured powder. Well-dissoluble in water.
