What is Cyanocobalamin?

Cyanocobalamin is one of the vitamin B complex, which has a strong anti-pernicious anemia effect. It is the name given to the crystal of vitamin B12, a factor indispensable for the development of bacteria and animals. In addition to containing C, H, O, and N, it also contains P and Co, which is a part of the a-D-ribose conjugate of 5,6-dimethylbenzimidazole (dimethe-rbenzimidazole). A.R.Todd et al. proposed the structural formula. As shown in the figure, because the cyano group is coordinated on the cobalt, it is called cyanocobalamin. The maximum absorption in aqueous solution is 278,361,548 nanometers. In 1948, E.L.Rickes in the United States and E.L.Smith in the United Kingdom each independently obtained crystals from the liver. Since then, this substance has also been obtained from a certain actinomycete (StrePtomyces griseum).

Feed additives

Cyanocobalamin (Vitamin B12) is an indispensable micronutrient for the growth of the body. Most animal plant feeds do not contain Cyanocobalamin (Vitamin B12). Animals rely on the synthesis of microorganisms in the gastrointestinal tract on the one hand, and rely on external additions on the other. In order to meet the needs of animal vitamins, vitamin additives must be added.

Non-ruminant animals such as pigs and chickens lack Cyanocobalamin powder, which is mainly manifested by stagnant growth and development, and a few pigs may have mild normal red blood cell anemia. In addition, it can also reduce the hatchability of chickens and the reproductive rate of pigs. The clinical symptoms of deficiency include loss of appetite, growth arrest, simple anemia, and severe neurological symptoms.

Feed Cyanocobalamin (Vitamin B12) can promote the growth and development of poultry, especially young poultry and young animals.
