Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...
A series of trials involving Coturnix quail, turkey and chicken
eggs was conducted to determine the effects on hatching performance
of varying amounts of oxygen and carbon dioxide during storage in
plastic bags filled with nitrogen or air. Storage periods of 6 and 13
days were studied in tests involving...
Four experiments were conducted (1961-1964) for the primary
purpose of studying the milk and milk constituent yields of dairy cows
under dry lot and pasture systems of management. The secondary
purpose was to compare the health and breeding performance of cows
under these two systems.
Ninety-eight cows of the Holstein...

Radiation induced heat generation rates of several nonfissionable materials were measured calorimetrically in a nuclear reactor environment. The calorimeter was uniquely designed to allow many materials of grossly different heat generation rates to be measured. heat transfer characteristics of the calorimeter were determined analytically and experimentally. Materials were chosen to...
Studies on the absorption of C¹⁴ carboxyl labeled 2, 4-dichlorophenoxyacetic
acid by a susceptible plant (bean) and and resistant
plants (corn and bluegrass) indicated that the chemical was readily
absorbed by all species of plants from a foliar application. Approximately
22% and 42% of the applied chemical was absorbed by...
Isocitrate-NADP oxidoreductase activity in mitochondrial and
soluble fractions was determined for hearts, livers and brains of
chick embryos at various stages of development. One-half to two-thirds
of the activity in brain and liver homogenates is located in the
soluble fraction. Supernatant activity increases in these organs to a
maximum during...
An experiment was conducted to determine the best method to
establish subterranean clover on medusahead infested ranges in
Western Oregon. Secondary objectives of this study were to determind
the effects of management treatments on (a) subterranean
clover density, (b) density of medusahead and other vegetation, and
(c) yield of subterranean...
The purpose of this thesis is to examine the methods and criteria
developed for rating actual and potential agricultural land in the
United States. It is motivated by the apparent increasing competition
for quality space created by the expanding population, and by the belief
that land rating and classification are...
The purpose of the study was to attempt to develop a methodological
approach which would tap the contribution of the literary
artist to the understanding of human behavior. It was assumed that
a content analysis of the social attitudes expressed in fiction would
yield data which was complimentary, if not...
