Seasonal Changes in Quality of Some Important Range Grasses

Chemical constituents and IVDDM of hybrid cattail from a South Dakota prairie pothole

“…Prior to spike emergence, CP ranged from 14.8% to 12.1% and IVDDM ranged from 65.2% to 58.5% (Table 3). These CP values are higher than those reported by Kamstra (1973) Smith 1962, Pritchard et al 1963).…”

Nutrient content and phenology of cool‐season grasses of Peru*

“…The CP concentration of S. ichu is similar to values reported for S. comata and S. viriduta in South Dakota (Kamstra, 1973;Cogswell and Kamstra, 1976). The high CP concentration determined for S. brachyphylla was comparable lo that for S. comata in Idaho (Murray et al, 1978).…”

“…IVDMD values for cool-season grasses of the Peruvian Andes generally were higher than for warm-season grasses of the southeastern United States (Lewis et al, 1975). Within-species comparisons show that 5. brachyphylla is higher in digestibility than that determined for S. comata (Wallace et al, 1972) and S. viridula in the USA (Kamstra, 1973). Digestibility for the genus Festuca was similar to values from Wales and the southern United States (Moore and Mott, 1973).…”

The Stage of Maturity and Its Effect upon the Chemical Composition of Four Native Range Species

“…In the natural biome situation, the grazing animal selects the more palatable species such as blue grama if adequate range conditions are maintained. As suggested by a previous study in southwestem South Dakota (Kamstra, 1973), prairie species are individualistic. This was shown by significant species-bydate interaction for all parameters tested (Tables 3 and 5).…”

“…Kamstra (1973) discussed the nutrient and digestive potential of important range species at the Cottonwood Range Field Station in southwestern South Dakota. This paper presents information on importantcooland warm-season species in northwestern South Dakota at the Antelope Range Field Station.…”
