摘要

The need to conserve biodiversity in grasslands has drawn much attention lately.We recently indicated that a species-rich plant community provides grazing cattle with adequate mineral intake, particularly trace elements.It is considered that the increase of plant species richness in the diet may affect rumen conditions, but there is no information on the relationship between them.In this study, mineral intake and rumen conditions were investigated for cattle and sheep grazed in paddocks with different plant species richness;high species counts (HS: 65-72) and low species counts (LS: 27-29), at the Field Science Center, Graduated School of Agricultural Science, Tohoku University, Japan (38° 44′ N, 140° 15′ E, 300-600 m in elevation).
