Selenium Fertilization of Pastures for Improved Forage Selenium Content (in English)

Mineral mixes commonly contain inorganic forms of Se that are poorly absorbed and utilized by ruminants compared with organic forms of Se. Another way to supply Se to livestock is through pasture plants. The enrichment of livestock feed crops with Se has been studied for many years in several countries. When inorganic Se is applied as fertilizer, plants convert it to the organic form, selenomethionine. This is absorbed by the animal and incorporated into tissues at a greater efficiency than inorganic forms.
