Access to trial data, mode of action, insights, and technical expertise on phytogenics
Fytera is a line of scientifically formulated PhytoComplex feed additives—plant-based solutions developed through rigorous phytotechnology research—within Selko, the feed additive brand of Trouw Nutrition. Fytera is developed in-house to support animal health, performance, and resilience—naturally, using phytogenics and bioactive compounds derived from secondary plant metabolites.
Phytogenics are based on secondary plant metabolites – those that are not directly involved in the plant’s growth or reproduction but help it survive in its environment. These metabolites have co-evolved with the animal kingdom and have the potential to interact with receptors in the animal (e.g., those located on the cells lining the intestinal tract) to elicit a broad range of biological responses.
When used for animal feed, we call these secondary plant metabolites ‘phyto-actives’. For our Fytera products, we carefully select and combine those plants and their phyto-actives that produce the desired response to the target challenge in the target animal. We call this: harnessing nature’s complexity to tackle the complex challenges our farm animals face!
At Selko, we believe in the power of nature—refined by science. Fytera® is the result of years of research into how phytochemicals and phytotechnology interact with animal physiology. We don’t just use plants—we discover new ones, validate how they work, and ensure they’re delivered with precision. From lab to farm, we control every step of the process to guarantee performance, safety, and consistency.
Fytera® is PhytoComplexes done right—leveraging the full spectrum of plant bioactive compounds to help you raise healthy and productive animals, sustainably.
