Conditioning bunchgrass on elk winter range

Creator:

Westenskow, Kathy Jo

Abstract:

Research was conducted near the Starkey Experimental Forest and Range in northeastern Oregon. Effects of defoliating bluebunch wheatgrass (Agropyron spicatum (Pursh) Scribn. and Smith) to increase the quality of regrowth available on elk (Cervus elaphus nelsoni) winter range were studied from 1988 through 1990. Clipping treatments were implemented to condition...

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...

Masters Thesis
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...
