Individual Differences in Retronasal Odor Responsiveness : Effects of Aging and Concurrent Taste

Creator:: Flaherty, Tyler J.
Abstract:: Taste sensitivity has been considered the primary chemosensory factor in studies of chemical senses and ingestive behavior. However, recent research has shown that retronasal olfaction is at least equally important in food preference and selection. Additionally, taste has been shown to modulate perceived intensity of retronasally perceived odors. The objectives...

Spring nitrogen and cultivar effects on winter canola (Brassica napus L.) production in western Oregon

Creator:: Ferguson, Brock T.
Abstract:: Limited information is available on the effects of applied spring nitrogen (N) and cultivar on winter canola (Brassica napus L.) production in high-rainfall environments. The objectives of this investigation were: (i) to determine the effects of spring N and winter canola cultivars on seed and oil production characteristics, and (ii)...

Preliminary investigation of artificial incubation of emu eggs, and alternative feeds and management techniques for emu chicks up to ten weeks of age

Creator:: Allen, Carol Ann
Abstract:: A preliminary study was conducted to establish baseline data for emu artificial egg incubation and emu chick growth and management. Three experiments examined factors affecting hatchability of emu eggs that occur prior to and during artificial incubation. Characteristics analyzed were egg storage duration, hen age, egg weight, egg index, shell...

Nongenomic inhibition of oxytocin binding by progesterone in ovine uteri

Creator:: Dunlap, Kathrin Anson
Abstract:: Effects of progesterone (P₄) and mifepristone (RU 486) on binding of oxytocin (OT) to its ovine uterine receptor (OTR) were studied in two experiments. Two additional experiments were conducted to evaluate specific binding sites for P4 in endometrial plasma membranes. In Exp. 1, ovariectomized ewes were injected with estradiol-17β (E₂)...

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...

Yeast culture improves lactation performance and metabolic status in transition dairy cows

Creator:: Ramsing, Erica M.
Abstract:: Yeast culture supplementation has been used to improve the health and performance of dairy cows for the last 25 years. To evaluate the effect of a Saccharomyces cerevisiae fermentation product (Diamond V Original XP™) on the health and production of peripartal Holstein cows, two research studies were conducted. The first...

Involvement of the Ets-1 transcription factor in early bovine and porcine embryo development

Creator:: Stauber, Leah
Abstract:: Early embryo development is dependent on maternally derived RNA and protein synthesized during oogenesis. In the bovine embryo this dependence lasts until the 8-16 cell stage, at which time embryonic transcripts become essential for continued development. One proposed mechanism for this transition from maternal to zygotic control of development (maternal...

The role of the plasminogen activator system in the etiology of ovarian follicular cysts in dairy cattle

Creator:: McNeel, Anthony Kent
Abstract:: Cystic ovarian disease (COD) is an anovulatory condition in cattle that afflicts between 6-18% of all dairy cows in the US. Ovulation is dependent on the plasminogen activator (PA) family of proteases and protease inhibitor for proteolysis, culminating in follicular rupture. Failure of the follicle to ovulate suggests an aberration...

Quantification of state-and-transition model components utilizing long-term ecological response data following one-seed juniper treatment on a deep sand savannah ecological site

Creator:: Shaver, Patrick L.
Abstract:: A proposed state-and-transition model (STM) for the Deep Sand Savannah ecological site in central New Mexico was developed using historical data and expert knowledge. This STM was tested utilizing data from short and long term one-seed juniper (Juniperus monosperma (Engelm.) Sarg.) control experiments initiated in 1981 and 1985. Utilizing data...

Modeling animal movement to manage landscapes

Creator:: Larson-Praplan, Stephanie
Abstract:: Managing rangelands with livestock grazing is a tool that can be applied to obtain vegetation management objectives. Animals utilize available resources, which vary in quantity and quality, across the landscape. Their movements are adjusted to the spatial and temporal heterogeneity of resource distribution. Controlling livestock distribution is fundamental to economically...
