We recommend using 1000 - 2000 g of VANNAGEN® / tonne of feed for shrimp.
VANNAGEN® is a specific formulation of yeast and yeast extract: PSB-Complex®.Recommended dosage1000-2000 g / tonne of feed
Withdrawal periodNone
StabilityVANNAGEN® is heat resistant and can be mixed with feed before pelleting or extruding
PackagingVANNAGEN® is packed in 25 kg polyethylene-lined white 5-ply paper bags
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 nutrients 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.
