C-Met 40
Applications:
Fish (freshwater fish and marine fish), Shrimp, Crab, Soft-shelled turtle, Eel, Turtle, Seashell and other aquatic animals
Definition:
The imbalance of amino acid in feed is not only decrease the utilization rate of protein, but also increase the cost of feeding and pollute environment. Now, the best method is to add amino acid in feed directly. For example, in feed of livestock and poultry, the general method is to add methionine 98% directly. However, lots of scientific research shows that it is not very effective to add methionine 98% in aquatic feed directly, because there is a time difference on the absorption of aquatic animals between the free-state methionine 98% and amino acid combined with feed protein, and common methionine 98% dissolves in water very quickly. Aiming at the physiological character of the alimentary canal of aquatic animals, we choose natural coating materials and take the most advanced biological technology of controlling release to be succeeded in developing a new feed additives for aquatic feed, C-Met 40. C-Met 40 can be released in the alimentary canal of aquatic animals at the fixed speed, the fixed place and the fixed time. The stability of C-Met 40 in water is also increased.
Specification:
Appearance: Off-white and light yellow powder
Active ingredients: microcapsulated Methionine≥40%
Function:
- Choose natural materials as coating materials, which can be decomposed by enzyme in the alimentary canal of aquatic animals. Thus, realize the high efficiency of sustained release.
- Balance amino acid in feed, increase nutrition and conversion rate of feed, decrease pollution to water environment.
- It is a new protein source for aquatic feed, reducing the use of fishmeal and lowering the cost of aquatic feed.
- Homogeneous granular, free flowing, strong stability.
Dosage:
Add in feed, according to the demand for methionine
Packaging: 25kg/bag
Storage: Keep in ventilated and dry place and avoid light.
Shelf life: 18 months in original packaging.
