Mineral nutrition is one of the most complicated and least understood components of nutrition. For years, producers and researchers alike have known about the need for mineral supplementation; however, development of mineral supplements to meet the requirements of grazing cattle often becomes a difficult and challenging problem due to 1) changes in animal requirements with stage and level of production, 2) difference in forage supply of minerals, and 3) methods to supply cost-effective supplemental minerals that ensure adequate intake and bioavailability (Greene, 1999).
