This study was conducted to delineate the cause or causes of
winter deaths in deer and to provide information from which emergency
feed could be formulated. Deer were shot at monthly intervals through
the winter in Wallowa County, Oregon. Samples from the rumen, liver,
mandible, blood and feces were taken...
Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...
Taste responses of the Columbian black-tailed deer,
Odocoileus hemionus columbianus (Richardson), were determined
by use of the two-choice preference test method, where the choices
were tap water and tap water-chemical solutions in ascending
concentrations. The chemicals tested were: the sugars, glucose
and sucrose; the sodium salts of chloride (NaC1) and...
Most of the nutritionally related difficulties of winter feeding
deer apparently result from either poor acceptability of artificial
rations or digestive disturbances that result from feeding starved
animals feeds to which they are not accustomed. Reported in this
thesis are studies conducted with both captive and wild deer concerning
acceptability...
Preliminary studies with a dog (Canis familiaris) and a coyote
(Canis latrans) showed that these carnivores can serve as definitive
hosts in the life cycle of Sarcocystis fusiformis of cattle (Bos
taurus) and a microscopic Sarcocystis of mule deer (Odocoileus
hemionus hemionus). Preliminary studies to determine effects of the
cervine...
An important segment of outdoor recreational activity in
eastern Oregon is based on the harvest of deer. The deer population
can be altered in two ways. Rangeland, which provides feed and
cover for deer, can be improved through public or private investments
or hunting regulations can be changed. This study...
Natality of black-tailed deer in McDonald State Forest was determined by examination of 147 reproductive tracts. Yearlings collected from November of 1968 to May of 1970 had an average of 0.79 corpora lutea per doe, and adults 1.76 corpora lutea per doe. Yearlings collected during the spring in 1969 and...
