The impact of three stocking intensities and four grazing treatments on the carbohydrate reserves of perennial ryegrass (Lolium perenne L.)

Creator:: El Hassan, Babiker Ahmed, 1940-
Abstract:: A study was conducted during 1974 and 1975 to evaluate the impact of stocking intensity and season of grazing upon carbohydrate concentration, biomass of storage organs, and total carbohydrate per plant in the roots and crowns of perennial ryegrass (Lolium perenne L.) in improved rangelands in Western Oregon. The stocking...

Sediment potentials for selected ecological land units in central Oregon

Creator:: Mattison, Jeffrey L.
Abstract:: During the summers of 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of Crook County, in central Oregon. The Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a...

A comparison of four methods used in determining the diets of large herbivores

Creator:: McInnis, Michael Lindsay
Abstract:: Esophageal fistulation, stomach content analysis, fecal analysis, and ocular-estimate-by-plot are four of the most publicized methods of determining the diets of large herbivores. The principal objective of this study was to compare the relative values of each of these methods based upon information collected from bi-fistulated (esophageal and rumen) sheep...

Diet and feeding behavior of cattle at risk to dietary acute bovine pulmonary emphysema (DABPE)

Creator:: Elliott, Jon Carner
Abstract:: The objectives of this study were to determine the diets of cattle at risk to DABPE on stress and inciting pastures and to determine if segregated feeding groups of cattle displayed differential susceptibility to DABPE. Stress pastures were classified and mapped by plant communities and segregated feeding group areas. Cattle...

Spring, summer and fall use by cattle and big game on foothill rangelands

Creator:: Miller, Richard F.
Abstract:: The objectives of this study were to evaluate environmental factors influencing use of several plant communities by cattle, elk and deer; determine under story production by plant species and the amount utilized by cattle, elk and deer in certain plant communities; evaluate the interactions of range use between cattle, elk...

Cattle grazing habits and movements related to riparian habitats and forested ranges with inference to acute dietary bovine pulmonary emphysema (ADBPE)

Creator:: Roath, Leonard Roy
Abstract:: Grazing on the mountainous forested ranges of the Camp Creek Unit, Malhuer National Forest, was typified by irregular distribution of free-ranging cattle. A combination of management and physical, topographic constraints caused cattle to concentrate on the riparian zone early in the grazing season in 1977 and 1978. A large percentage...
