Arbiom completes successful trial in rainbow trout

Friday, February 5, 2021

Arbiom finished the trials evaluating its alternative protein ingredient SylPro® for use in rainbow trout feed. The study was conducted at the French National Research Institute for Agriculture, Food,  and Environment (INRAE) at St. Pée sur Nivelle, a leading French research institute, as part of AQUAEXCEL 2020 Transnational Access Program (TNA). The goal was to evaluate the nutritional performance of SylPro in rainbow trout diets. In the study, feeds were formulated with SylPro as a replacement for fishmeal and/or plant-based protein-rich ingredients.  

The study results showed that SylPro was a suitable replacement for both plant proteins and fishmeal based on feed conversion ratio (FCR), specific growth rate (SGR) and body weight gain (BWG) when used in aquafeeds up to a 20% inclusion level. In addition, the inclusion of SylPro improved performance in fishmeal-free diets. The results also point to an exceptional protein digestibility of SylPro compared to standard protein ingredients. The research team saw no statistical differences in mortality throughout the study. 

“The results of the trout feed study are consistent with previous trial results and once again demonstrate the nutritional and functional performance SylPro offers feed formulators. We are eager to follow-up on these findings, especially as they relate to fish health,” said Ricardo Ekmay, senior vice president of Nutrition and Product Development for Arbiom.  

“We are pleased with the results of the trout study conducted in collaboration with Arbiom. In order to enable a sustainable food future, science-backed protein sources must be available to producers and consumers,” said Sandrine Skiba, researcher with INRAE.  

Arbiom SylPro is produced using wood-derived media in a fermentation stage followed by downstream processing to produce the product, which is comprised of dried inactive yeast cells. The company developed SylPro® to address the challenges of producing sustainable, nutritional,  traceable protein ingredients, and also improving gut health for fish, land animals and ultimately humans. 

“With this trial, we continue our momentum commercializing Arbiom’s innovative protein product,” said Marc Chevrel, Arbiom CEO. “We are confident SylPro delivers significant, consistent and valuable benefits in terms of improving animal health, human nutrition, production efficiencies and overall sustainability of our food chain.  Arbiom’s latest trial shows consistent commercial product performance of SylPro, and ultimately value for producers and consumers. How we feed our food, including aquaculture-farmed fish, is of critical importance, with significant sustainability implications for producers and society-at-large,” said Chevrel.
