Five common cereal grasses (Michigan Winter barley, Wintok oats, Balbo rye, Tenmarq wheat, Clarkan wheat) and annual ryegrass were clipped throughout the fall and winter growing season to simulate grazing and the clippings analyzed for carotene, riboflavin, pantothenic acid, nicotinic acid and thiamine. Significant differences in the concentration of all of these components were found in samples collected at different times. In general, differences between cereals were not statistically significant, although in one year significant differences in pantothenic acid content were disclosed. These cereal grasses contain appreciable amounts of carotene, riboflavin, nicotinic acid, and thiamine and a lesser amount of pantothenic acid. The vitamin content for all varieties for all season was as follows: carotene, 578; riboflavin, 28; nicotinic acid, 53; pantothenic acid, 19; and thiamine, 12 micrograms per gram of fresh tissue on a dry weight basis. Drying at 65 degrees C resulted in a significant loss in riboflavin content, no change in nicotinic acid content, and an apparent increase in pantothenic acid content.
