• Beef Production on Lodgepole Pine-Pinegrass Range in Southern British Columbia

      McLean, A. (Society for Range Management, 1967-07-01)
      Yearling steers on lodgepole pine-pinegrass summer range in British Columbia had an average daily gain of 1.75 lb for 103 days per year over a 5-year period. The average gain per acre was 19.3 lb for the season and the average stocking rate was 4.8 acres per AUM. Pinegrass, which provided over 50% of the forage yield, was readily accepted by cattle during early summer but became unpalatable by mid August.
    • Cheatgrass Range in Southern Idaho: Seasonal Cattle Gains and Grazing Capacities

      Murray, R. B.; KIemmedson, J. O. (Society for Range Management, 1968-09-01)
      Yearling cattle gained weight satisfactorily on cheatgrass range under rotational (moderate) and continuous (moderate and heavy) grazing systems during a 3-year study. This study was designed to determine effects of these systems on the rangeland-not on individual plant species. Assignment of these systems to different pastures each year precluded evaluation of long-term vegetal response to the treatments. Weight gain was greatest in late spring. Grazing capacity of the range and cattle gain per acre increased through the summer, then declined. Yearly variation in production of forage and beef was apparently due to weather. Grazing capacity and beef production increased under continuous heavy grazing, but possible vegetation changes not evaluated in this study make heavy grazing undesirable.
    • Grazing Studies on Native Range, Crested Wheatgrass, and Russian Wildrye Pastures

      Smoliak, S. (Society for Range Management, 1968-01-01)
      Weight gains per acre of yearling ewes on continuously grazed crested wheatgrass and Russian wildrye pastures averaged 21.7 and 26.3 lb, or 2.6 and 3.2 times the gain of yearling ewes on native range (8.3 lb). On rotation and free-choice systems of grazing the gains per acre averaged 16.5 and 18.5 lb, or 2.0 and 2.2 times those on native range. Over the 10-year period the seeded pastures were stocked three times as heavily as the native range. Ewes rotated themselves on the various pastures under a free-choice system, going first to crested wheatgrass, then to native range and lastly to Russian wildrye.
