Maintenance Energy Requirements, Ruminal Temperature, Walking Activity, and Plasma Concentrations of IGF-I, Thyroxine, and Triiodothyronine of Gestating Beef Cows
Pye, Timothy A. (Oklahoma State University, 2011-07-01)Three experiments with spring calving, Angus cows (Exp. 1, n = 40; Exp. 2, n = 32; Exp. 3, n = 32) were conducted to determine the effects of maintenance energy requirement (MR) on plasma concentrations of insulin-like ... -
Management of newly received feedlot cattle and the effects of bovine respiratory disease on feedlot performance and carcass attributes
Holland, Ben Patrick (2009-07)The effects of serum haptoglobin (Hp) concentration on growing phase performance and Bovine Respiratory Disease (BRD) morbidity and mortality was evaluated using 337 heifer calves (initial BW = 241.3). Heifers were allocated ... -
Management Strategies and Live Weight Gain of Steers Grazing Old World Bluestem and Subsequent Feedlot Performance and Carcass Characteristics
Kircher, Patrick David (2001-08-01) -
Mitigating Enteric Methane Emissions from Grazing Beef Cattle Through Fat Supplementation
Beck, Matthew Raymond (2017-07-01)Ruminant animals produce a significant amount of the greenhouse gases that contribute to climate change, with the majority of emissions arising from grazing ruminant systems. Chief among these gases is methane which arises ... -
Nutrient intake and digestion by cattle grazing midgrass prairie rangeland and plains bluestream pasture
Gunter, Stacey Alan (1993-05) -
Nutritional regulation of reproduction and ovarian function in postpartum beef cows
Ciccioli, Norberto Horacio (2002-08) -
Optimal stocking density for dual-purpose winter wheat production
Kaitibie, Simeon; Epplin, Francis M.; Brorsen, B. Wade; Horn, Gerald W.; Krenzer, Eugene G., Jr.; Paisley, Steven I. (Cambridge University Press, 2003-04)Dual-purpose winter wheat production is an important economic enterprise in the southern Great Plains of the United States. Because of the complex interactions involved in producing wheat grain and beef gain from a single ... -
Performance of light vs. heavy weight steers grazing Plains Old World bluestem at three stocking rates
Ackerman, Callan J. (1999-07) -
Protein Requirements for the Young Growing Boar
Tyler, Ralph Warren (Oklahoma State University, 1978-12-01) -
Relationship of Maternal Dietary Energy Intake to Milk Production, Body Composition, and Efficiency of Calf Growth
Spencer, Courtney Marie (2017-12-01)The purpose of this research is to define cow and calf production responses and overall pair efficiency to a range of feed energy intakes provided to lactating beef cows. Two experiments were conducted in consecutive years ... -
Ruminal Motility and Bloat Potential of Wheat Pasture Stockers
Frost, Denzil Fay (Oklahoma State University, 1978-07-01) -
Ruminal protein degradation in beef cattle
Swanek, Scott S. (2007-05)Scope and Method of Study: In Exp. 1, five ruminally cannulated steers were used in a 5 x 5 Latin square design experiment to determine the effects of increasing urea level on intake, nutrient digestion, nitrogen balance ... -
Simulation Model of Weight Gains of Angus and Hereford Calves from Birth to Weaning in Oklahoma
Cannon, Helen Marguerite (Oklahoma State University, 1982-12-01) -
Stocker Cattle Performance and Nitrogen Use Efficiency in Old World Bluestem Grazing Programs
Wallis, Brody Donovan (2016-05-01)In grazing systems only 5-30% of ingested nitrogen (N) is retained in BW gain of growing beef cattle. A two-year study was conducted to evaluate N fertilizer and DDGS as sources of N and N use efficiency for growing beef ... -
Studies on the influence of particle size and level of feed intake on ruminal digestion
