I the last link it says fish meal and brewers yeast contain selenium

The commonly used forms are sodium selenite and, more recently, organic selenium chelates. Feeds grown on high-selenium soils are sometimes necessarily used in poultry rations and are good sources of selenium. Fish meal and dried brewer’s yeast are also rich in available selenium.

Some research shows that selenium is also thought to aid in fighting some cancers.
