    The form of existence in nature: TMAO widely exists in nature, and is the natural content of aquatic products, which distinguishes aquatic products from other animals. Different from the features of DMPT,TMAO not only exists in aquatic products, but also inside freshwater fish, which has less ratio than inside sea fish.

    Usage & dosage

    For sea-water shrimp, fish, eel & crab: 1.0-2.0 KG/Ton complete feed

    For fresh-water shrimp & Fish: 1.0-1.5 KG/Ton complete feed


    1. Promote proliferation of muscle cell to increase the growth of muscle tissue.
    2. Increase the volume of bile and reduce fat deposition.
    3. Regulate the osmotic pressure and accelerate mitosis in aquatic animals.
    4. Stable protein structure.
    5. Increase feed conversion rate.
    6. Increase lean meat percentage.
    7. A good attractant which strongly promotes the feeding behavior.


    1.TMAO has weak oxidability, so it should be avoided to contact with other feed additives with reducibility. It may also consume certain antioxidant.

    2.Foreign patent reports that TMAO can reduce the intestinal absorption rate for Fe(reduce more than 70%), so the Fe balance in formula should be noticed.



    Package: 25kg/bag

    Shelf life: 12 Months

    Note : the product is easy to absorb moisture. If blocked or crushed within one year, it doesn’t affect the quality.
