Accuracy of Diet Nutritive Value Predictions from a Fecal NIRS Profiling System for Grazing Beef Cattle
O'Neil, Andrew D. (2001-12-01) -
Effect of Time of Weaning on Performance of Young and Mature Beef Cows and Their Calves in a Fall Calving System
Hudson, Melissa D. (Oklahoma State University, 2007-07-01)Time of weaning influenced cow body weight and body condition score. At the beginning of the calving season, NW cows were heavier and had greater fat reserves than LW cows. Postpartum BW and BCS loss was significantly ... -
Effects of Cow Mature Size on Intake Calf Weight and Milk Yield in a Spring-calving Commercial Cow/Calf Operation
Mourer, Gant Larry (Oklahoma State University, 2012-07-01)Two experiments were conducted to evaluate the effects of mature BW and cow efficiency on DMI, milk yield, and calf weaning BW on spring calving Angus sired commercial cows. Cows one SD above and one SD below the mean were ... -
Energy Requirements and Production Efficiency of Lactating Beef Cows in a Drylot System
Bayliff, Corbit Leroy (2016-07-01)Population growth and alternative use of agricultural lands continues at an alarming rate, posing many challenges to food growers worldwide� particularly for meat-animal producers. Limited grazing land availability, adverse ... -
Evaluation of Milk Yield and Udder Characteristics in Beef Cows Sired by High and Low Milk EPD Bulls
Stutts, Kyle Jeffrey (2001-08-01) -
Evaluation of Techniques to Estimate Carcass Composition of Beef Cattle
Ross, Rebecca Ann (Oklahoma State University, 2005-12-01)Percentages of moisture, fat, protein, and ash were determined on 46 Angus x Angus-Hereford steers, by means of proximate analysis. Urea space, specific gravity, and 9-10-11 rib section proximate analysis were performed ... -
Fertilization and Dried Distillers Grains Supplementation Effects on Performance and N Recovery by Stocker Cattle Grazing Old World Bluestem
Gunter, Phillip Allen (Oklahoma State University, 2014-12-01)A 2-yr study evaluated the efficacy of using dried distillers grains plus solubles (DDGS) as a substitute for nitrogen (N) or N and phosphorus (P) fertilizer in stocker cattle grazing Plains Old World bluestem. Cattle were ... -
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) -
Measurement of Exhaled Nitric Oxide and Carbon Dioxide in the Breath of Beef Calves
Holland, Ben Patrick (Oklahoma State University, 2006-07-01)Two experiments were conducted to test the ability to measure exhaled nitric oxide (eNO) and exhaled carbon dioxide (eCO 2 ) in the breath of healthy beef calves and calves showing clinical signs of bovine respiratory ... -
Predicting dry matter intake of gestating and lactating beef cows
Gross, Megan A. (2020-12)In 1996, the NASEM beef cattle committee developed and published an equation to estimate cow feed intake using results from studies conducted or published between 1979 and 1993. The same equation was recommended for use ... -
Preliminary biological and economic analysis of capsaicin feed additive in feedlot rations
Wiebe, Erica (2022-05)This research investigates capsaicin feed additive in beef finishing rations to assess its preliminary biological and economic outcomes. A trial was conducted at Buffalo Feeders, LLC located at Buffalo, OK with capsaicin ... -
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 ... -
U.S. Beef Producers' Current Use and Perceptions of Social Media as a Communications Tool
Gillespie, Jenny Lynn (Oklahoma State University, 2011-12-01)The purpose of this nationwide study was to determine U.S. beef producers' current use and perceptions of social media as a communications tool. Participants in this study (n=498) were randomly selected from a population ... -
