Response of Canada milkvetch (Astragalus canadensis var. mortonii (Nutt.) Wats.) to range and forest improvement practices in Northeastern Oregon

Creator:: Wood, Benjamin William
Abstract:: The response of Canada milkvetch (Astragalus canadensis var. mortonii) to range and forest improvement practices was studied on a stand of mixed-coniferous forest which was clear -cut and burned in 1963 and 1964, respectively. The field studies were conducted on the Hall Ranch of the Eastern Oregon Experiment Station during...

Plant communities in the old-growth forests of North Coastal Oregon

Creator:: Hines, William W. (William Wester)
Abstract:: This study was conducted in the old-growth forests of Clatsop, Tillamook, and Lincoln counties, Oregon. The three objectives of the research were to describe and classify the near-climax plant communities found within the forests, to relate the associes described by a previous study to the forest communities characterized by the...

Mineral assessment of open range livestock production on the Warm Springs Indian Reservation

Creator:: Brummer, Fara Ann
Abstract:: The Warm Springs Reservation is located in central Oregon. Livestock production consists of beef (commercial with an Angus, Horned Hereford base) and roping (Corriente and Longhorn) cattle and horses that forage most of the year on the open range within reservation boundaries. Forage consists of annual and perennial grasses and...

Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

Twenty-five years of grazing research at Meadow Creek in the Starkey Experimental Forest and Range

Creator:: Walburger, Kenric
Abstract:: Three studies were conducted to evaluate different grazing systems on mixed conifer rangelands in eastern Oregon, and photo points and aerial photography was used to determine effects of 25 years of cattle grazing on stream channel changes and vegetation responses. The first study was designed to determine if grazing treatment...

Some techniques for determining fecal output and digestibility of range forage by cattle

Creator:: Pryor, William Joseph
Abstract:: A Cr₂0₃, and cellulose fibre mixture was used with cattle, in three grazing and two semi-restricted experiments, to study the mode of its excretion, the possibility of using it in a once-daily dosing and grab-sample regime to estimate fecal output and in a field experiment to test a hypothesis involving...

Nutrition and management of the beef unit for production of slaughter animals on range and improved pastures in southeastern Oregon

Creator:: Daugherty, Dennis A.
Abstract:: Studies were conducted over a two year period to evaluate alternative finishing methods for spring and fall-born beef cattle. Management alternatives from birth to slaughter included season of calving, lactating cow nutrition, preweaning calf nutrition, weaning age, calf and yearling winter nutrition, range and irrigated pasture supplementation, grazing practice, range...

Forage intake and related performance criteria of spring and fall calving cow-calf pairs on summer range

Creator:: Kartchner, Rex John
Abstract:: Three studies during three consecutive summers were conducted at the Squaw Butte Experiment Station to estimate relative and quantitative forage intake of spring and fall calving cow-calf pairs on summer range. In a drylot study (experiment 1) individual animal consumption of fescue or meadow hay cut at 2- to 10-day...

The use of natural plant extracts as a feed additive to prevent laminitis in lactating dairy cows

Creator:: Pierson, Miranda L.
Abstract:: Two experiments were conducted looking at both acute and sub-acute laminitis. An acute nutritional induction model was used to examine whether blood profiles and gene expression are similar to other studies conducted using an endotoxin induction model. Twelve sheep were randomly assigned to three treatment groups which were control, 4-hour...

Nutritional characteristics of dormant season grazing within a winterfat (Krascheninnikovia lanata (Gueldenstaedt)) dominated plant community, and the effect of seedbed preparation on the emergence and survival of winterfat and squirreltail (Elymus elymoides (Raf.) Swezey) seedlings

Creator:: Estes, Mark G.
Abstract:: The effect of seedbed preparation on the emergence and survival of winterfat (Krascheninnikovia lanata (Gueldenstaedt)) and squirreltail (Elymus elymoides (Raf.) Swezey)) seedlings was determined, while quantifying nutritional changes through the dormant season for four range species. In November of 2004 twenty 9m x 8m plots were randomly prepared with one...
