Cattle grazing in semiarid forestlands: Habitat selection during periods of drought

Creator:: Roever, C. L., DelCurto, T., Rowland, M., Vavra, M., and Wisdom, M.
Abstract:: Climate change models are predicting increased frequency and severity of droughts in arid and semiarid environments, and these areas are responsible for much of the world's livestock production. Because cattle (Bos taurus) grazing can impact the abundance, distribution, and ecological function of native plant and animal communities, it is important...

Potential limitations of NRC in predicting energetic requirements of beef females within western U.S. grazing systems

Creator:: Petersen, M. K., Mueller, C. J., Mulliniks, J. T., Roberts, A. J., DelCurto, Tim, and Waterman, R. C.
Abstract:: Assessment of beef cow energy balance and efficiency in grazing-extensive rangelands has occurred on a nominal basis over short time intervals and has not accounted for the complexity of metabolic and digestive responses; behavioral adaptations to climatic, terrain, and vegetation variables; and documentation of the effects of nutrient form and...

Late gestation supplementation of beef cows differing in body condition score: Effects on cow and calf performance

Creator:: Bohnert, David W., Stalker, L. A., Mills, R. R., Nyman, A., Falck, S. J., and Cooke, Reinaldo Fernandes
Abstract:: A 2-yr study utilizing 120 mature, crossbred (Angus × Herford) cows/year, evaluated the influence of cow BCS and dried distillers grains with solubles (DDGS) supplementation during late gestation on cow performance and productivity of subsequent offspring. Treatments were arranged as a 2 × 2 factorial in a randomized complete block...

Effects of camelina meal supplementation on ruminal forage degradability, performance, and physiological responses of beef cattle

Creator:: Cappellozza, B. I., Cooke, R. F., Bohnert, D. W., Cherian, G., and Carroll, J. A.
Abstract:: Three experiments compared ruminal, physiological, and performance responses of beef steers consuming hay ad libitum and receiving grain-based supplements without (control) or with (CAM) the inclusion of camelina meal. In Exp. 1, 9 steers fitted with ruminal cannulas received CAM (2.04 kg of DM/d; n = 5) or control (2.20...

Bovine acute-phase response after different doses of corticotropin-releasing hormone challenge¹,²,³

Creator:: Cooke, R. F., Carroll, J. A., Dailey, J., Cappellozza, B. I., and Bohnert, D. W.
Abstract:: The objective was to compare the acute-phase response of steers receiving different doses of bovine corticotropin-releasing hormone (CRH). Fourteen weaned Angus steers (BW = 191 ± 2.1 kg, age = 167 ± 4.7 d) fitted with an indwelling jugular catheter and a rectal temperature (RT) monitoring device were assigned to...

Species Composition and Diversity on Northwestern Bunchgrass Prairie Rangelands

Creator:: Darambazar, Enkhjargal, DelCurto, Timothy, Damiran, Daalkhaijav, Clark, Abe, and Taylor, Robert
Abstract:: Management and conservation of rangelands are increasingly concerned with maintaining productivity, species composition, and diversity of native plant communities. We estimated aboveground annual productivity, species composition, and diversity of a native bunchgrass type community across 1152, 0.5 m2 plots at The Nature Conservancy’s Zumwalt Prairie Preserve in northeastern Oregon. Standing...

Visual Obstruction: Weight Technique for Estimating Production on Northwestern Bunchgrass Prairie Rangelands

Creator:: Damiran, Daalkhaijav, DelCurto, Timothy, Darambazar, Enkhjargal, Clark, Abe A., Kennedy, Patricia L., and Taylor, Robert
Abstract:: The estimation of standing crop is important in the management of rangeland resources. Direct measurements by clipping, drying, and weighing of herbaceous vegetation are time-consuming and labor-intensive. Therefore, non-destructive methods for efficiently and accurately estimating standing crop are needed in rangeland forage management. We assessed a visual obstruction (VO) technique...

Changes in Forage Quantity and Quality with Continued Cattle Grazing in a Mountain Riparian Pasture

Creator:: Darambazar, Enkhjargal, DelCurto, Timothy, Ackerman, Callan, Pulsipher, Gary, and Damiran, Daalkhaijav
Abstract:: The objective of this study was to evaluate changes in the quantity, quality, and moisture of available forage in a riparian pasture, and shrub utilization by cattle during a 30-d late summer grazing period. A riparian pasture (44.7 ha) in northeast of Oregon was grazed with 30 yearlings (419 kg,...

Influence of previous cattle and elk grazing on the subsequent quality and quantity of diets for cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav, DelCurto, Timothy, Findholt, Scott, Pulsipher, Gary, and Johnson, Bruce
Abstract:: A study was conducted to determine foraging efficiency of cattle, mule deer, and elk in response to previous grazing by elk and cattle. Four enclosures, in previously logged mixed conifer (Abies grandis) rangelands were chosen, and within each enclosure, three 0.75 ha pastures were either: 1) ungrazed, 2) grazed by...

Crop Response to Lime in the Western United States

Creator:: Jackson, T. L. (Thomas Lloyd), 1922- and Reisenauer, H. M.
Abstract:: The western states include a complex combination of geological, topographical, climatic, and vegetative features. The region extends through 1900 km of latitude and contains three major north-south, storm-directing mountain systems. Most of the region is arid (annual precipitation < 50 em); however, sizeable agriculturally important areas west of the Cascade...
