Research was initiated at the Squaw Butte Experimental Range in
southeastern Oregon to study the influence of crested wheatgrass
(Agropyron desertorum (Fisch.) Schult. ) herbage availability on relative
dry matter intake (DMI) of yearling steers. Herbage dry matter
production on an 18 ha range and daily fecal production of yearling...
A study was conducted over a two year period, 1973 through
1974, on perennial ryegrass-subclover pastures with stocking rates
of 7.4 (moderate), 9. 9 (heavy), and 12.4 (overstocked) ewes per
hectare to establish guidelines on stocking intensity for dryland
improved pastures in western Oregon. Climatic conditions varied
annually and caused...
As part of investigations to evaluate the suitability of sheep grazing in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range, this research was designed to evaluate the effectiveness of sheep grazing in suppressing unwanted vegetation, determine seasonal variations in forage quality, and investigate the impact of sheep grazing on big...
A three-year investigation was conducted during 1980-1982 to
evaluate the potential of using herded sheep as a silvicultural tool
to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations
of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest
in May soon after bud break. Averaged over the 2 years of grazing,...
