• Site Variation in Forage Qualities of Mountain Mahogany and Serviceberry

      Kufeld, R. C.; Stevens, M. L.; Bowden, D. C. (Society for Range Management, 1985-09-01)
      Nutrient and fiber content and in vitro digestible dry matter (IVDDM) were measured in mountain mahogany (Cercocarpus montanus) and serviceberry (Amelanchier alnifolia) samples collected during January from 8 geographic areas distributed throughout the western half of Colorado. Coefficients of variation (CV) in dry matter content, cell content, crude protein, soluble carbohydrate, cell walls, holocellulose and IVDDM were 10% or less for both species. Winter variation in these parameters appears to be small enough to permit using a constant value for them in calculating winter nutritional status of big game rangelands.
