Lallemand Animal Nutrition will support Aquaculture Europe 2022 which will take place in Rimini, Italy from September 27-30. The company will contribute to the event by sponsoring the Health Management – Gut Health oral session on September 30 which will be introduced by Eric Leclercq, Lallemand Animal Nutrition’s aquaculture R&D manager.

Leclercq’s presentation will be entitled How to brew healthy performing fish with modern yeast and will focus on the modes of action and applications of different yeast technologies.

“Functional nutrition is a pillar of preventive health to which yeast-based solutions historically contribute. Recent progress in harnessing the diversity of microbial fractions and host responses bolsters their span of application in support of fish health, welfare, and performance. This year’s contributions to Aquaculture Europe 2022 together highlight how specific microbial biotechnologies can be selectively deployed to provide a tangible contribution to an array of current aquaculture challenges,” said Leclercq.

Furthermore, the company’s R&D department will present six scientific studies during the event.

The dose-response of seawater Atlantic salmon (Salmo salar) to a mannan-rich yeast cell wall ingredient trades between growth and health benefits

In this study, a commercially available MOS-rich yeast cell wall (AGRIMOS, Lallemand Animal Nutrition) is shown to bring graded zootechnical and/or skin health benefits depending on the dose and background status of the fish.

Pikeperch (Sander lucioperca) larval rearing optimization: Utilization of lactic acid bacteria for improving microbiome diversity and digestive enzyme activity

This study explored the effects of Lallemand’s flagship probiotic bacteria, Pediococcus acidilactici CNCM I-4622 (BACTOCELL), for larval rearing. It indicates a positive effect of the probiotic by enhancing early enzyme activity, controlling microbiome diversity and improving larvae growth and survival rates.

Modulation of physiological responses in Atlantic salmon exposed to stressor conditions: Hydrolyzed Debaryomyces hansenii in functional feeds can improve fish health and welfare

This study, in partnership with the Norwegian University of Life Sciences, evaluated the potential of a novel non-Saccharomyces yeast derivative to mitigate the impact of stress factors on salmon immunity.

Mitigation of Atlantic salmon winter-ulcer disease (Moritella viscosa) using a novel yeast-based functional ingredient

In this study, conducted in partnership with the University of Plymouth, a novel yeast cell wall supplemented for five weeks increased resilience to a winter ulcer outbreak under controlled conditions. Skin wound development and mortality rate were mitigated. In addition, the healing of the infectious wound was fastened.

Effect of a probiotic mix on fish welfare and stress response: Influence of the time of day of administration

The effects of some probiotics on mammals’ brain-gut axis — i.e. psychobiotic effects — are not well described in fish, as they are in some other species. In partnership with the University of Murcia, this study broke new ground in this area. It documented a reduction of anxiety-like behavior associated with modulation of stress biomarkers and of GABAergic signaling upon supplementation with a probiotic holding documented psychobiotic effects in humans (Cerebiome, Lallemand Health Solutions).

Modulation of skin and intestinal mucosal barrier function in zebrafish (Danio rerio) fed different postbiotics and a probiotic from lactobacilli

This study explored the potential of postbiotics (e.g. heat-killed, inactivated lactobacilli) for fish and other animals using zebrafish as a vertebrate model system. It demonstrated the potential of bacterial postbiotics to support intestinal and skin immunity through the modulation of both cellular and humoral immune responses.
