Preliminary study on feeding attraction activities of TMAO for Penaeus vanname

       Additives were used to study the effect on ingestion behaviour of Penaeus vanname. The result showed TMAO had stronger attraction on the Penaeus vanname as compared with the addition Ala, Gly,Met,Lys,Phe,Betaine and DMPT respectively. The effect of concentration of TMAO on the ingestion behaviour of the Penaeus vanname was also investigated. The first reaction appeared sooner with the increase of the concentration of TMAO at a concentration range of 0.5-3.0 mg/kg. The results show that TMAO can be used as a feeding attractant in the feed for Penaeus vanname.

Here more information about TMAO 

Name: Trimethylamine oxide, dihydrate

Abbreviation: TMAO

Formula：C₃H₁₃NO₃

Molecular Weight：111.14

Physical and Chemical Properties:

Appearance：off-white crystal powder

Melting point：93--95℃

Solubility: soluble in water（45.4gram/100ml）、methanol，slightly soluble in ethanol，insoluble in diethyl ether or benzene

Well-sealed, store in a cool dry place and keep away from moisture and light

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

Feature:

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.

Instructions:

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.

Assay：≥98%

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.
