Calcium in Hay
The following two charts list calcium in forages. All hay has some moisture in it.
Chart #1 lists the percent of calcium as fed.
Chart #2 provides the percent of calcium in hay with all moisture removed. Variations occur from field to field. Remember that growing conditions, maturity, and soil nutrients affect all mineral content.
