Description
Mineral element characteristics of Bromus inermis were determined in 2 week intervals from May 15 to October 15 in a four-year study. Clipped samples were separated to leaf and stem fractions. In year 4, 3 ruminally fistulated cows were used to determine diet selection 6 times during the growing season, and were used to determine in situ mineral disappearance of clipped grass. Based on rumen evacuation and in situ methodology elemental concentrations in Bromus inermis exhibited seasonal flux and in the conditions of this study cows did not select a diet different from clipped samples in elements other than Fe and P.
