Selko

What Selko does

Selko is the specialty feed additive brand of Nutreco, a global animal nutrition company ultimately owned by SHV Holdings. It develops and manufactures organic acid blends, PhytoComplex botanical solutions, hydroxy and organic trace minerals, and proprietary dosing equipment for feed mills and livestock producers. Its portfolio is organized into four product categories (Organic Acids, PhytoComplex Solutions, Trace Minerals, Dosing Equipment) and nine specialized programmes covering feed safety, antibiotic reduction, mycotoxin management, heat stress, and trace mineral optimization. Customers are feed mills, poultry, swine, ruminant, and aquaculture operations, as well as food-industry players using spent yeast or co-products; products are shipped to more than 80 countries.

The technology stack includes PhytoComplex technology for preserving full-spectrum plant bioactives, buffered organic acid blends with moisture-management penetration, patent-pending ActiProp technology for mould cell wall disruption, patented OptiSize particle technology for hydroxy trace minerals, and Fibosel enzymatic beta-glucan exposure. Manufacturing is concentrated at a GMP+, Fami-QS, HACCP, ISO 9001:2015, and ISO 17025:2017 certified facility in Tilburg, Netherlands. The brand is sold primarily through Trouw Nutrition's global sales network, with direct technical engagement and quote-based, volume-tiered pricing on multi-year contracts.

Selko's research program is anchored by 30+ years of Optimin trace mineral work and 20+ years of IntelliBond development, recently extended through collaborations with ICAR-CIBA (India) and Dankook University. Notable commercial partnerships include a Revalet-based spent yeast preservation program with Heineken Global Supply Chain. In January 2025 IntelliBond was admitted to the GFLI product carbon footprint database, enabling feed mills to claim verified Scope 3 emission reductions when using Selko inputs. A peer-reviewed publication on Selacid GG against Vibriosis in shrimp was released in the same period, signaling a targeted push into aquaculture gut health.
