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...

The ability of a yeast-derived cell wall preparation to minimize toxic effects of high-alkaloid tall fescue straw in beef cattle

Creator:: Merrill, Melissa L.
Abstract:: Two experiments were conducted to evaluate the influence of a yeast-derived cell wall preparation (YCW) on forage intake and digestibility, ruminal fermentation characteristics, serum prolactin and prolactin stores, and milk production in beef cattle consuming high-alkaloid tall fescue straw. In Exp. 1, 16 Angus x Hereford ruminally cannulated steers (200...

Effects of sire breed on growth, feed efficiency, and carcass traits of cross-bred lambs slaughtered at three weights

Creator:: Collins, Debora Ann
Abstract:: This study examined the effects of sire breed and weight on the performance of 117 crossbred wether lambs born at the Oregon State University Agricultural Experiment Station, Corvallis. Lambs were produced by mating Clun Forest,Polypay, Dorset, Border Leicester, and Suffolk sires to Columbia-type ewes. After weaning at approximately 90 days...

Identification of novel immune molecular pathways and response markers to OmniGen-AF® supplementation in a rat model

Creator:: Branson, Jennifer A.
Abstract:: OmniGen-AF® (OG; Prince Agri Products, Inc., Quincy, IL) is a feed additive containing brewers dehydrated yeast and B-vitamins that supports immune function in ruminant livestock. Targeted profiling of immune-associated genes in whole blood is an effective platform for identification of a) novel molecular pathways and b) immune response markers to...

Effects of prostaglandin F2alpha on neutrophil populations, uterine health and reproductive performance in dairy cows, Effects of prostaglandin F₂α on neutrophil populations, uterine health and reproductive performance in dairy cows

Creator:: Lulay, Adrienne McCracken
Abstract:: Incidences of uterine infections in dairy cattle are high between parturition and Day 21 postpartum. Dairy cows with uterine infections are at risk for prolonged periods of days open and multiple services before becoming pregnant. Neutrophils are the first wave of immune system defense against uterine contamination. Neutrophil function seems...

Evaluation of wet brewers' grain ensiled with low quality forages

Creator:: Kennedy, Matthew A. (Matthew August)
Abstract:: Two experiments were conducted to evaluate the use of wet brewers' grain (WBG) alone and with straw so it can be used as part of the sole ration for ruminants. In Exp. 1, WBG was ensued alone and was mixed with one of two straws, wheat or tall fescue grass...

Management Strategies to Improve Immune Function and Performance of Feeder Cattle

Creator:: Lippolis, Katana D.
Abstract:: Three experiments evaluated the effects of different management strategies on immune function and performance of feeder cattle. The objective of experiment 1 was to compare the effects of anticipating, delaying, or vaccinating against Bovine Respiratory Disease (BRD) at the time of weaning and feedlot entry on growth, DMI, and plasma...

Tissue analysis and winter feeding of deer

Creator:: Fowle, Kenneth Edward
Abstract:: 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...

Certain physiological and pharmacological effects of radiation on rabbits

Creator:: Wagelie, Edwin Gan
Abstract:: Data were taken, following irradiation exposure to 100r and 300r cumulative dose, on 89 rabbits of three breeds that vary greatly in body size. Hematological, intestinal motility, and ear vascularity examinations were performed. Least square estimates have been obtained and an analysis of variance has been conducted in order estimate...
