Age and Source Verified Preconditioned Feeder Cattle: Costs and Value
Donnell, Jeri Denise (Oklahoma State University, 2007-05-01)The purpose was to: 1. Determine key factors influencing preconditioning cost and returns; 2. Determine the premium for age and source verified, preconditioned calves sold at a public livestock market. Data were provided ... -
Analysis of seasonal effects on nutritive value of native forages in the southern Great Plains and its relationship to sampling method
Montgomery, Dagan (2022-05)The objective was to investigate forage value throughout the year using near infrared reflectance spectroscopy (NIRS) while comparing sample types. Samples were collected from tallgrass native range pastures being grazed ... -
Comparison of Tenderness, Palatability and Retail Caselife of Enhanced Cow Subprimals to Control Cow and USDA Select Subprimals
Rose, Mindy N. (Oklahoma State University, 2008-12-01)The objective of this study was to determine the impact of enhancement of cow subprimals on tenderness, palatability, and retail caselife as compared to control cow subprimals and USDA Select subprimals. The data from this ... -
Economic comparison of Angus, Red Angus, and Aberdeen-influenced cow-calf production
Munson, Meredith Anne (2020-05)This research investigates the differences in cow-calf profitability between Angus-, Red Angus-, and Aberdeen-Influenced herds. Differences in revenue by dam and sire breed were estimated using birth weight, calving interval, ... -
Effect of competition for an automated supplement feeder on supplement intake behavior of beef stocker steers
Husz, Taylor (2019-12)The objective of this research was to determine the effect of competition for a feeding space at an automated supplement feeder on supplement intake behavior. A 2-yr study was conducted; each yr, 128 mixed-breed beef steers ... -
Effect of Direct Fed Microbials on Concentrations of Glucose and Insulin in Plasma and Animal Performance
Davis, Michael Patrick (Oklahoma State University, 2006-07-01)Sixty-two Angus x Hereford heifers were used to determine the effects of feeding direct fed microbials for 8 wk prior to the breeding season on concentrations of insulin and glucose in plasma, animal performance and ... -
Effect of Growing Beef Replacement Heifers on Wheat Pasture Before and During Breeding on Reproductive Peformance
Bryant, Marsha H. (Oklahoma State University, 2009-07-01)Unsatisfactory breeding performance has been reported when replacement heifers have been exposed to bulls or AI while grazing small grains. The objective of this study was to compare reproductive performance of heifers ... -
Effect of increasing ruminal propionate on feed intake and glucose metabolism in steers fed a finishing diet
Rathert, Abigail (2021-05)Two experiments were conducted to investigate the effects of increased propionate supply to steers fed a feedlot finishing diet on dry matter intake, feeding behavior, glucose clearance rate, insulin response and hepatic ... -
Effect of Supplemenation Method on Supplement Intake and Performance of Steers Grazing Dormant Tallgrass Prairie.
Williams, Garret Don (2017-07-01)The objective of this experiment was to determine the effect of supplementation method (hand-fed vs. ad-libitum access) on supplement intake and performance of beef steers grazing dormant native tallgrass prairie. The ... -
Effects of Early and Late Fall Calving of Beef Cows on Reproduction and Calf Growth
Kastner, Dale W. (Oklahoma State University, 2006-12-01)Effects of early and late fall calving on gestation length, pregnancy rate, and weaning weight were evaluated in Angus x Hereford cows during 4 years. Sixty fall calving cows were blocked according to age and prior calving ... -
Effects of Timing of Weaning on Performance and Energy Utilization of Primiparous Beef Cows
Wiseman, Aksel Robert (2018-07-01)Early weaning is used to minimize cow nutrient requirements in situations where feed inputs are scarce or expensive. For many years, maintenance energy requirements have been assumed to be 20% greater in lactating compared ... -
Evaluating producer decision making surrounding calving date in the U.S. Southern Plains
Upton, Amanda J. (2021-07)Calving date directly impacts cow-calf producers' profits, and indirectly effects the entire beef cow industry. January and February calving puts calves at risk for severe cold exposure. A calf exposed to winter weather ... -
Genomic Effects on Milk Fatty Acid Composition of Beef Cows and Its Influences on Calf Pre-weaning Growth
Deng, Zhuo (Oklahoma State University, 2014-07-01)Research has shown that milk yield (MWT) accounts for only a moderate amount of variation in pre-weaning average daily gain (PRWADG). This study was proved that milk fatty acid methyl esters (FAME), alone and in combination ... -
Identifying the Contributions of Interferon Responses to Disease and Pregnancy in Cattle
Chase, Jessica Lee (2015-07-01)Two significant challenges the cattle industry is facing are respiratory disease and infertility. The type I interferon (IFN) pathway plays a pivotal role in both disease and pregnancy. The type I IFN pathway is interrupted ... -
Intensified Cow-calf Production in the Southern Great Plains Incorporating Native Rangeland, Wheat Pasture, Semi-confinement and Cover Crops
Cole, Jarrod (2015-12-01)Decreasing acres of grazing land along with increasing demand in red meat suggests the need for intensified beef cattle production systems. The objective of the two year trial was to decrease land area per unit of production ... -
Oklahoma Quality Beef Network: Price Premiums from a Preconditioning Program
Ratcliff, Chandra Dawn (Oklahoma State University, 2004-07-01)The proposed study determined if an extra value existed in the preconditioned calves involved in this particular program. It is going to estimate the price differences between cattle sold through the OQBN program and ... -
