Corbion’s algae-based omega-3 liquid suspension can be used at varying inclusion levels and up to three times the industry standard with high retention of omega-3 fatty acids, feed quality, digestibility, supporting sustainable growth in the aquaculture industry
Primarily funded by the
The first round of research sought to determine optimal inclusion levels of AlgaPrime™ DHA LS — Corbion’s algae-based omega-3 DHA-rich ingredient in liquid suspension — in feed for
An array of diets was produced and tested, from a control feed using fish meal and soy protein concentrate to feeds with the high inclusion levels of AlgaPrime™ DHA LS. Applying a method that enables numerous comparisons, researchers determined that inclusion of 100 g/kg AlgaPrime™ DHA LS in the mixture was commercially interesting, considering the levels of lipids mostly used in the feed mix.
Based on the industry standard practices, researchers tested AlgaPrime™ DHA LS in the pellet coating process and were able to add up to 14% inclusion in a final feed with 36% lipids, which is far above the relevant industrial application levels of omega-3.
In a uncommon study design that combines the technical application and nutrition science and after the feed production trials, the research group then looked at four diets containing AlgaPrime™ DHA in the mix, the coating, and a combination of the two, using AlgaPrime™ DHA LS at 10% and 20% inclusions. All four diets showed high nutrient digestibility in
These findings represent an important step for fish nutrition, illustrating the viability of sustainability gains by increasing the use of ingredients with high concentrations of omega-3, something a reliance on fish oil alone could not accomplish. At the same time, it is great news to the aquaculture industry, enabling the strategic management of omega-3 levels in feed to facilitate the production growth, a much-needed tool in view of increasing pressure on our oceans and the supply gap of traditional marine resources.
“The application of AlgaPrime™ DHA at different inclusion rates minimize manufacturing process constrains due to its high omega-3 DHA content, optimal lipid level, ideal mixability, and thermostability, giving feed manufactures a new tool to explore and develop omega-3 DHA inclusions and advance nutrition for health,” said
AlgaPrime™ DHA LS is made from a single-cell algae strain grown at scale using industrial fermentation to produce DHA while ensuring feasibility for feed manufacturers and salmon producers. With a higher DHA concentration compared to fish oil and other alternatives, inclusion of AlgaPrime™ DHA LS in feed can maintain or raise omega-3 levels in healthy diets, reducing the dependency for fish oil, thereby helping to preserve the environment.
