All Bergophor mineral feed for dairy cows, calves and cattle contain the Bergophor selenium combination for ruminants.
Selenium takes an important role in the thyroid metabolism, in the ovaries and the placenta. A sufficient selenium provision protects cells from oxidative damage and provides for an intact immune system. Selenium deficiency can cause fertility problems and an increased somatic cell count.


Besides sodium selenite and rumen protected sodium selenite it also contains organically bound selenium in form of selenium yeast. This triple combination ensures the selenium provision of high performance cows even under strong physiological pressure (time around birth, first third of lactation etc.).
