Trials in Shrimp / List of trials

We recommend using 1000 - 2000 g of VANNAGEN® / tonne of feed for shrimp.



VANNAGEN® an exceptional feed supplement

VANNAGEN® is a unique formulation of purified RNA and purified nucleotides.

Although not yet defined as essential nutrients, numerous scientifically confirmed trials demonstrated that purified nucleic acids must be regarded as a management tool to control stress and disease while maintaining or enhancing performance in fish and crustaceans. Having been successfully used in all such applications, and more, they foster development, participate in cellular and molecular repair mechanisms and ensure unhindered cell proliferation without affecting growth, development or reproduction upon environmental, physical and pathogenic challenges.

Recommended dosage
1000-2000 g / tonne of feed

Withdrawal period
None

Stability
VANNAGEN® is heat resistant and can be mixed with feed before pelleting or extruding

Packaging
VANNAGEN® is packed in 25kg polyethylene-lined white 5-ply paper bags



Trials in Shrimp

VANNAGEN® supports shrimp to better cope with stress




Salinity stress induced in Penaeus monodon during the 60 days trial period.



Cumulative mortality due to stress induced by salinity fluctuation in Penaeus monodon fed a control diet or VANNAGEN®-fortified diets

 


Summary of performance data. The results show a significant improvement of end weight, feed conversion rate and mortality with both 1000 g and 2000 g of VANNAGEN® / tonne of feed. The mortality in both VANNAGEN® groups dropped drastically compared to the control group. Additionally, improved protein efficiency rate leads to lower ammonia production in the ponds. 




VANNAGEN® improves the performance of shrimp




Summary of performance data of the pond trial while including 2000 g of VANNAGEN® / tonne of feed.


VANNAGEN® ameliorates the quality of shrimp




Carcass composition of shrimp fed a VANNAGEN® fortified diet compared to control shrimp.


VANNAGEN® enhances cellular immune response in shrimp




Haemocyte counts of different shrimp after inclusion of VANNAGEN® into the diet.


The haemocyte counts provided conclusive support for effects of VANNAGEN®-supplemented diets. In both small and large shrimp, total haemocyte counts increased with VANNAGEN®-supplemented diets compared to shrimp fed control diets. This effect was seen in both P. monodon and in P. merguensis.

Haemocytes are key cells for mopping up invading pathogens, so this result is commercially important. The effect was more pronounced in juveniles, with increases in total haemocyte counts of more than 100%. This may be expected given that nucleotides will be in high demand in rapidly growing animals. In larger shrimp the effects were also notable. There were increases in total haemocyte count per millilitre of haemolymph up to 30% higher in test subjects as compared to controls.
