Why use Selenigrass?

Selenium is a vital trace element and is required by all animals. The natural route for selenium intake by ruminant animals is from their green feed diet. The selenium in Selenigrass is a slow release granular form of selenium, which is the natural solution to boost low plant selenium levels. Selenium is released throughout the plant growing cycle boosting the selenium content at harvest or during grazing.
