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...
This investigation was undertaken to characterize and evaluate
the forage production and utilization of the successional vegetation
of the mixed conifer forest.
Field studies were carried out during the summers of 1962
through 1964 at the Eastern Oregon Experiment Station Hall Ranch
which is located 12 miles southeast of Union,...
Recent emphasis on range improvement of sagebrush-bunch-grass
types in Oregon has underscored the need for better understanding
of their importance to deer winter range management. The
objectives of this study were to evaluate the impact of various sagebrush
control practices on the composition, production, and utilization
of deer forage plants...
Research was conducted in a mixed-coniferous forest stand
that was clearcut, burned, and seeded in order to study early plant
succession, grazing influences on native and introduced species, big
game use, and environmental relationships vegetation, animal,
and environmental research was carried out from 1965 to 1967 in
three, five-acre exclosures...
Animal dietary preferences have been studied by feeding-site
examinations, animal observation, and stomach and esophageal collections.
Analysis of fecal material for undigested plant cuticle is
another means for obtaining the same information.
This study was conducted to: (1) prepare a microscope slide
series depicting the surface features of leaves and...
In 1959, a large scale grazing study in western Oregon was
initiated to compare the value of perennial ryegrass (Lolium perenne
L.) with subclover (Trifolium subterraneum L.) and tall fescue
(Festuca arundinacea Schreb.) with subclover, and to evaluate common
use grazing on them. The present investigation was undertaken
to determine...
