On October 15th, Olmix organized the “Immuno’Science forum” in Porto, an event dedicated to immunity and gut health, to highlight the importance of those functions to secure animal health and performance. This gathering brought together international keynote speakers, covering various species such as poultry, swine, ruminants, and aquaculture.
The forum was enriched by the presence of representatives from 14 different countries, fostering a global exchange of ideas and knowledge. The attendees could discover the potential of seaweed and yeasts technologies to provide solutions to reinforce immune response and gut health.
Swine Sesion
Anne Morvan, Portfolio Manager of Health range at Olmix, initiated the session by giving an introduction of the swine disease PRRS to give context to the following presentations.
Nicolas Bertho is a senior scientist at INRAE in France. After an extensive tenure with Isabelle Schwartz-Cornil’s team in Jouy-en-Josas, he is now leading a team at the INRAE research lab BIOEPAR at Nantes Veterinary School. In his presentation, Nicolas provided an overview of key swine immunology concepts. He revisited previous collaborative research with Olmix and shared findings from the ongoing immunity project «ONIRIS» which focuses on the effects of oral seaweed extracts (MSP®) supplementation during the delivery of an attenuated PRRSV vaccine. The study highlights that this supplementation modulates systemic inflammatory cytokines and improves the anti-PRRSV humoral response.
To date, the project has demonstrated a range of effects of Searup® on two types of immune cells: monocytes and alveolar macrophages. These effects include a short-term pro-inflammatory response, long-term anti-inflammatory and antiviral benefits, and a reduced susceptibility to the PRRS virus. In a second experiment, notable results were observed when Searup® was administered one day before and two days after vaccination. This approach enhanced the immune response by modulating cytokine levels, decreasing serum load, and extending the duration of PRRS vaccine viremia. Additionally, it led to increased production of anti-PRRSV IgG. A third and final experiment is planned for 2025, where further promising results from oral seaweed supplementation are anticipated to address the significant challenges posed by PRRS.
Following Nicolas’s presentation, Francisco Rocha Pinto, Product Manager for the Vet range at Olmix, discussed the positioning and application of Searup® in swine. He also outlined Olmix’s recommendations for addressing PRRS through a comprehensive product mix solution added both in drinking water (Searup®) and in the feed (Algimun®). Finalizing his session, he shared important results from a field trial with Searup® on farrowing and weaning performance when applied around sows’ vaccination and before farrowing (+0.34 born alive piglets/litter and +0.46 weaned piglets/litter, allowing an increase in net profit/litter of +3.8 Euros).
Olmix has been well known for many years as an expert in the field of Mycotoxins risk. With this scientific forum, attendees could learn that Olmix marine bioactive ingredient extraction know-how has led to the development of solutions targeting immunomodulation and gut barrier function. Following the acquisition of Yes Synergy, specialized in upcycled yeast technologies, Olmix is incorporating new solutions in its portfolio. Attendees could discover the innovative, reliable, natural and sustainable solutions that the several seaweed and yeasts fractions offer to enhance immunity and gut health to boost performance of animals. By promoting overall health status and improving animal performance in different contexts, particularly in challenging conditions, Olmix has demonstrated to be a reliable partner and supplier of natural solutions to support the growth and sustainability of modern livestock farming stakeholders.
