Orffa Excential Selenium feed additive
Werkendam 4251 LC
Excential Selenium from Orffa has been shown in intensive trial work in laying hens and dairy cows that its bioavailability is superior over selenized yeast, the traditional way of obtaining organic selenium. Selenium is critical in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from oxidative damage and infection. The product has been authorized in Europe as nutritional feed additive for use in all animal species.
