Potential barriers to movements and habitat selection of pygmy rabbits (Brachylagus idahoensis) after experimental translocation

Creator:: Lawes, Timothy J. (Timothy James)
Abstract:: I assessed potential barriers to dispersal using homing tendency and investigated the movements and settlement site selection of pygmy rabbits (Brachylagus idahoensis) after short distance translocations in southeastern Oregon from June – December 2008. I captured, radio marked, and translocated 59 pygmy rabbits 1-2 km across landscapes with (1) continuous...

The effects of timber harvest and herbivory on understory vegetation and composition of beef cattle diets on forested rangelands

Creator:: Walburger, Kenric J.
Abstract:: The objectives of the experiment were to: 1) determine the relationship between overstory canopy cover and ungulate herbivory on understory production composition and diversity and 2) determine the effects of timber harvest, ungulate herbivory and season of use on botanical composition and nutritional quality of beef cattle diets. Three randomly...

Movements and Settlement Site Selection of Pygmy Rabbits After Experimental Translocation

Creator:: Lawes, Timothy J., Anthony, Robert G., Robinson, W. Douglas, Forbes, James T., and Lorton, Glenn A.
Abstract:: We investigated the movements and selection of settlement sites of translocated pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon from June to December 2008. We captured, radio tagged, and translocated 59 pygmy rabbits across big sagebrush (Artemisia tridentata ssp.) habitat with 3 categories of landscape fragmentation. We used radio telemetry to...

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...

Nutritional and managerial considerations for wintering beef cattle in the northern Great Basin

Creator:: Brandyberry, Steven D.
Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...

The role of processors in the improvement and expansion of fruit crop production in the western state of Nigeria ; a case study

Creator:: Olufokunbi, Banwo
Abstract:: Four assumptions-- 1. That there is an effective and potential demand for processed fruit products in the Western State of Nigeria. 2. That current supply of raw materials in the Western State of Nigeria is more than sufficient to meet the increased demand which the short-term addition or expansion (or...

Quantities of prostaglandins in whole and extended bovine semen and their potential effect on fertility following insemination

Creator:: Jaeger, John Ralph
Abstract:: Our objectives were to determine 1) the concentration of prostaglandin F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α administered at the time of artificial insemination would improve conception rate. Concentration of PGF2α tended...

Influence of stocking density on grazing beef cattle performance, diet composition foraging efficiency, and diet quality on a late-spring early-summer native bunchgrass prairie

Creator:: Wyffels, Samuel A.
Abstract:: This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...

The influence of grazing systems on the performance and diet of yearling cattle

Creator:: Berry, Timothy James
Abstract:: Research was conducted at the Starkey Experimental Forest and Range in northeastern Oregon to determine cattle performance, diet quality, botanical composition of forage ingested, and production and utilization among rest-rotation, season-long, and deferred rotation grazing systems. The grazing season lasted from June 20 to October 10 of each year. Cows...

Evaluation of media inhibitory for lactic streptococcal bacteriophages

Creator:: Gulstrom, Timothy James
Abstract:: Seven commercially prepared brands of lactic streptococcal phage inhibitory media were obtained from their manufacturers. Comparisons between the different media were made with respect to buffering capacity, ability to support lactic streptococcal growth, ability to suppress bacteriophage replication, and ability to support Leuconostoc growth. Nonfat milk was used during experiments...
