Feed preservation and intestinal health are focus areas

In an era of increasing volatility in raw material prices and availability, one of the challenges facing the animal nutrition industry is the ability to secure sufficient good quality raw materials. Changing climate conditions impact on quality parameters like bacterial counts, yeast and mould prevalence. Demand for feed-to-food safety is also higher. Adding effective additives to animal feed helps reduce harmful microorganisms and mycotoxins at various stages in the feed-to-food chain, leading to improved quality at feed mill and farm level, thereby supporting animal health and production.

Rising global concern about antibiotics requires sustainable strategies to maintain animal production, while significantly reducing antibiotic use. Strategies for maintaining the good health and performance of production animals are multi-disciplinary and combine good farm management practices, including biosecurity and hygiene procedures, optimal feeding programmes, breeding programmes and health management. Applying feed additives to animal feed supports its quality and can impact positively on gut integrity, thereby improving animal performance.


Selko® Feed Additives was founded as Selko B.V., in 1983, as a leading manufacturer of preservatives for raw materials and finished feed. When Selko became part of Nutreco, in 2002, the portfolio grew to include health and nutrition additives.

Selko commercialises its products through Trouw Nutrition’s global sales organisation. Trouw Nutrition is a global leader in innovative feed specialties, premixes and nutritional services for the animal nutrition industry. Since 1931, its feed-to-food solutions have met the needs of feed producers, integrators and home mixers.  For more information please visit
