Vitamin 4 - choline, lecithin is a part - the most common phospholipids. The composition also includes lecithins linoleic, palmitic and oleic acids. Sensitive to lack of choline poultry and pigs.

Choline chloride - used in the composition of compound feed for livestock and poultry as a source of choline. Choline (vitamin B4) does in the body's vital functions, it is a substance of which the body is formed acetylcholine - one of the major mediators of nervous excitement. The lack of choline in the body of animals leads to the development of fatty infiltration and hemorrhagic degeneration of the liver and kidneys, thymus involution.

Choline is part of the phospholipid lecithin which is an important part of the body's cells. It plays an important role in the metabolism of phospholipids; involved in the synthesis of phospholipids in the liver. Choline is one of the main representatives of the so-called lipotropic substances that prevent or reduce fatty liver. It serves as an important source of methyl groups necessary for the body occurring biochemical processes.

The mechanism of action of choline is two things: first, it helps brain cells to grow better in the second part of choline is converted into a substance acetyl choline, a signal substance of the nervous system, which helps in learning and intellectual processes.

In practice, the need for increased choline at a high content of fat in the diet (which is particularly important for ensuring high hatchability), with the additional administration of vitamin B5 in the diet (choline antagonist) and providing minimum rate methionine diet.

Symptoms of deficiency of choline in the body: a sharp decline in productivity in chickens inflammation and an increase in the curvature of the joints (perozis), fatty liver and its subsequent degeneration, enlarged kidneys.
