Iron bolus

Prevent iron deficiency in calves with our iron bolus

Our iron bolus Irontop is a calf supplement that quickly corrects an iron deficiency in calves, using iron chelates for optimal intestinal absorption. Iron deficiency can lead to anemia in calves and is shown by dull hair, decreased drinking, pain, and less vital animals. We notice an iron deficiency in almost all newborn calves. 

Our iron bolus can be used for newborn calves, preferably after the intake of the first colostrum.
