ALLTECH - SEL-PLEX (2007) - 2 stars
Sel-Plex is defined according to the yeast strain number that is used for its production, this number also determine its physical and chemical
characteristics. Sel-Plex is prepared with a dead yeast which has been naturally enriched with selenium during fermentation process. In Sel-Plex, selenium is 97-99 % organic and most of it (63%) is seleniomethionine (antioxidant constituent of many enzymes). Animals metabolism and digestive system are particularly adapted to this form of selenium in comparison with sodium selenite which is the mineral form usually used in animals feed.
With Sel-Plex, selenium absorption and storage are clearly improved (by 3 times for absorption) whereas sodium selenite is not stored by animal. This property limits environment's pollution.
Due to its natural organic and low concentrated form, Sel-Plex is non toxic source in comparison with selenite which is highly toxic for animals and human. Sel-Plex supplemeritation allows a storage in final products such as milk, meat or eggs. At farm level, several trials demonstrated that selenium supplementation have improved reproduction (sperm quality, fertility, slow farrowing, still birth), muscles deseases (spraddle legs, white muscle deseases...). Sel-Plex improves the selenium status of progeny. Selenium plays also an essential role in immunity. The last research work conducted by Alltech concerned Nutrigenomic (influence of nutrient on gene expression). It has been shown recently that Sel-Plex modified the gene expression of 10% different genes.
