Comparisons of technologies in beef production systems
(2014-05)Beef steers (n = 180; initial BW = 250 � 19 kg) were randomized to one of two treatments in the pasture phase. Steers were implanted with 40 mg of TBA, 8 mg estradiol, and 29 mg tylosin tartrate (Conventional; CONV-Z) or ... -
Determining the existence of bunk preference in an automated individual intake system and the effects of increased roughage late in the finishing period on feedlot steer performance, intake, and efficiency
(2020-07)The objective of the first experiment was to determine the existence of bunk preference and if access to a preferred bunk affects performance, intake, and efficiency of feedlot steers. Angus steers (n = 123; initial BW = ... -
Economic thresholds of Wheat streak mosaic, feedlot cost of gain prediction, and joint adoption of cow-calf production practices
(2019-05)Wheat streak mosaic (WSM), caused by Wheat streak mosaic virus, which is transmitted by the wheat curl mite (Aceria tosichella Keifer), is the most widespread and economically important virus disease affecting winter wheat ... -
Economic Value of Igenity Panel Genotypic Information for Fed Cattle
(Oklahoma State University, 2010-05-01)Cattle phenotypes are determined by management and genetics. Beef carcass marbling, tenderness, weight, and fat content are economic traits that are affected by these factors. Economically-relevant traits are typically ... -
Evaluation of Diet Adaptation Programs and Supranutritional Dietary Antioxidants for Feedlot Cattle
(Oklahoma State University, 2010-12-01)To evaluate feedlot performance and carcass characteristics of finishing beef steers fed diets containing wet distiller's grains with solubles (WDGS) and supplemented with vitamin E, one hundred ninety-nine steers (370 ... -
Management of newly received feedlot cattle and the effects of bovine respiratory disease on feedlot performance and carcass attributes
(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 ... -
Nutritional and management strategies for high-risk beef calves during the receiving period
(2021-07)Crossbred beef steers (n = 605; initial BW = 255 +/- 8.3 kg) were randomly assigned to 1 of 2 treatments upon arrival to the feedlot. Steers were either administered metaphylactic antimicrobial treatment at arrival (MET) ... -
Use of near Infrared Reflectance Spectroscopy for the Characterization of Wheat and Barley Grain Entering Feedlots in Western Canada
(Oklahoma State University, 2014-05-01)The first experiment evaluated the use of near infrared reflectance spectroscopy (NIRS) for the nutrient prediction of wheat grain and the factors affecting in vitro dry matter digestibility (IVDMD) and in vitro kinetics ... -
Using whole cottonseed to replace dried distillers grains plus solubles and prairie hay in finishing cattle rations balanced for physically effective neutral detergent fiber
(2022-07)Two experiments were conducted to determine the effects of replacing prairie hay and dried distillers grains plus solubles (DDGS) with whole cottonseed (WCS) in finishing diets balanced for physically effective neutral ...
