Function and characteristic
Role in a wide range: to avoid the animal Vc deficiency, anemia, and promote connective tissue formation, prolonged molting period; promote antibody formation to improve immune function and anti-stress ability to reduce the toxic effects of metal ions in vivo.
Good stability:resistance to high temperature and high pressure, greatly reduce the loss during the feed processing caused by high temperature, humidity, heat and extrusion, avoid the loss of VC and the dissolving in water during storage period.
High availability:dynamic and slowly release in animal body, sustainedly participate in the reaction of organism, show physiological function.
Excellent effect:good fluidity of microgranule,can be used together with other feed not to affect the product's performance, to reduce culture cost and improve culture rate.
Methods and dosage: for the preparation of premixes, concentrates, added in the feed or used alone

Coating application of vitamin C
To overcome the common Vc in aquatic and animal feed processing, storage and use of the process of devastating losses, low bioavailability, poor economic characteristics. We Wellcome has developed a series of stabilization of vitamin C products, coated vitamin C is one of them. Stability, bioavailability, non-toxic side effects, is the biggest characteristic of coated Vc.
Stability
Under the same conditions by ordinary coated Vc Vc stability and comparison (see table below) can be seen that the stability of the coating is much higher than ordinary Vc Vc.

Bioavailability
¡¡¡¡Chinese Academy of Fishery Sciences Research Center of freshwater fish industry in the grass carp feeding trial showed that adding the test Vc compared with ordinary coated Vc, which can increase 11% by weight or more, feed conversion ratio decreased by 3% or more. Shanghai Fisheries University: Wang Chun, the cold did to the military crucian carp Vc of the requirements of the research show that: when the feed was added when the general Vc Vc and coating, and plasma from the liver is evident in the Vc content Vc Vc coating better than conventional bioavailability.
