Organic Selenium

Modern animal production practices, with their associated stress factors and high metabolism, increase oxidative stress. This leads to loss of performance, fertility and health problems for pigs, as well as decreased meat quality (oxidation). Due to its ability to incorporate mineral selenium into selenomethionine, a form readily available for animals. Selenium (Se) is an essential nutrient for life, with established requirement from 0.1 – 0.3 ppm to support basic functions.


Selisseo® 2% Se is an organic source of selenium consisting of hydroxy-selenomethionine or HMSeBA diluted on silica carrier, to be used in all species to supply 100% efficient selenium. Selisseo® 2% Se is the only pure source of hydroxy-selenomethionine on the market that exists in both forms : powder and liquid.


The selenium content of each ALKOSEL® R397 production batch is standardized using state of the art analytical techniques such as flame atomic absorption spectrometry (FAAS). The total selenium content in ALKOSEL®R397 is guaranteed to be 2000 ppm minimum and is almost totally in its organic form (>98%). Moreover, the strain Saccharomyces cerevisiae NCYC R397 has been specifi cally selected for its selenium bioavailability properties.
