Why should chicken feed supplement choline chloride?

First, chicken feed contains a certain amount of choline chloride, chicken body can also synthesize some, due to the increase of age of its synthesis capacity to improve, chicken demand for choline increases, especially chicks, but its synthesis speed can not meet the needs of growth and development, such as do not pay attention to the addition of deficiency. In addition, the body's ability to synthesize choline is related to the amount of choline added to the feed during the growth period, and the addition of too much choline to the growth period feed will cause the synthesis capacity of the chicken itself to reduce its own choline, which makes the chicken more sensitive to the lack of choline after adulthood.

Second, choline is synthesized in the liver, vitamin B12, methionine and folic acid play an important role in the synthesis of choline, so when poultry suffers from liver disease or insufficient content of vitamin B12, methionine and folic acid in feed, it can also cause choline deficiency. In addition, the raw materials for liver synthesis of choline are methionine and serine, if the level of choline in the feed is appropriate, methionine does not have to be used as a raw material for the synthesis of choline. Because choline is very cheap, the appropriate amount of choline can not only save methionine, but also be more economical

Third, the need for choline is related to the energy concentration of the diet, when fed high-energy and high-fat diets, on the one hand, the intake of chickens is reduced, the intake of choline is insufficient; on the other hand, the liver also needs more choline to synthesize lipoproteins to transport out liver fat, so attention should be paid to the addition of feed choline

Fourth, vitamins B2 and B5 are related to the utilization of choline in the body, and when it is deficient, it will cause the use of choline disorders, and similar choline deficiency will occur.
