Abstract
This article reviews the trace mineral and macro mineral content of small grain forages and the potential role in the health of cattle grazing the forages. Reasons for the variability of trace mineral content in small grain forages are discussed, as well as the role of antagonists, such as sulfur and molybdenum, in creating trace mineral deficiencies. The sampling of cattle for the determination of trace mineral statues is described, including which samples to collect for analysis, as well as sample handling. The authors offer a useful discussion on the vitamin content of small grain forages, and conclude that vitamin supplementation is not necessary.
