Black-tailed Prairie Dog and Large Ungulate Response to Fire on Mixed-grass Prairie
(Oklahoma State University, 2010-12-01)
Restoring historic fire-grazing regimes and the declining keystone species the black-tailed prairie dog (Cynomys ludovicianus) are two management priorities in North America's grasslands. My study sought to investigate the ...
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 ...
Development of a Multi-Scale Walkover Platform for Precision Livestock Management
(2019-05-01)
Stocker Cattle Operations are a vital part of the beef cattle industry in Oklahoma. One of the most vital pieces of information for a stocker cattle operation is the weight of each individual management. Walkover Scales ...
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 ...
Vegetation response to fire and domestic and native ungulate herbivory in a Wyoming big sagebrush ecosystem
(Oklahoma State University, 2011-12-01)
Coupling of fire and grazing as a landscape management tool is a global phenomenon in many diverse landscapes. While grazing exclosure studies examining the effects of livestock on rangelands have provided insight into the ...
Effects of Wet Distillers Grains Plus Solubles and Energy of the Health and Performance of Receiving Calves
(Oklahoma State University, 2012-12-01)
A randomized complete block design experiment utilizing 180 high-risk crossbred steers (initial BW = 212 ± 2 kg) was conducted to evaluate the effects of including wet distillers grains plus solubles (WDGS) in a 62% ...
Evaluation of Byproduct Combinations on Feedlot Performance, Carcass, and Fecal Characteristics
(Oklahoma State University, 2012-07-01)
The first experiment compared inclusion levels of a 1:1 blend of Sweet Bran (SB) and dried distiller's grains (DDGS) byproducts in a dry-rolled corn feedlot ration on performance, carcass merit, and fecal characteristics. ...
Modeling the Evolving Mexican Cattle and Beef Industry and the Economic Impacts of Additional Beef Fabrication
(Oklahoma State University, 2013-12-01)
Beef packing infrastructure in Mexico has changed dramatically in recent years with a significant proportion of domestic beef production now fabricated into boxed beef in place of the carcass based system that dominated ...
Utilization of near Infrared Reflectance Spectroscopy for the Evaluation and Characterization of Barley in Western Canada
(Oklahoma State University, 2013-12-01)
The first study evaluated near infrared reflectance spectroscopy (NIRS) for the determination of barley silage DM on as-is samples using either a commodity specific or broad based equation. A second study was conducted to ...
Development of Technology to Exclude Feral Animal Feed Consumption from Calf Creep Feeders
(Oklahoma State University, 2011-12-01)
A series of experiments was performed with the objective of creating a system to exclude feral animals from calf creep feeders. The first experiment evaluated three different electronic sensor systems for accuracy of ...
