Highest purity through our special production process.
In modern animal feed, selenium is added as a trace element because natural selenium contents in green fodder are too low. In dairy cattle feeding, the addition of sodium selenite as a feed additive is even standard. RETORTE is a feed-approved company, certified according to FAMI-QS. The in-house feed sup-plements RETOSEL and RETOJO are characterized by a particularly high purity of the preparations, compli-ant with all EU directives, as well as low-dust and thus optimized for further use.
