The Evaluation Of Feed Additives On Reducing Enteric Methane Production From Cattle, Reba L. Colin

Department of Animal Science: Dissertations, Theses, and Student Research

Environmental sustainability can be positively impacted by the inclusion of feed additives to reduce enteric methane production from cattle. Methane production can be affected by feed additives that either alter the rumen environment or act as methanogenesis inhibitors. A reduction in methane from cattle can contribute to meeting carbon neutrality.

A metabolism study was conducted to evaluate Alga 1.0, a product containing bromoform, fed to cattle to evaluate the effects on gas emissions. Treatments were (0, 69, or 103 g/d Alga 1.0) fed in a corn-based diet. Headbox-style indirect calorimeters were used to measure gas emissions. Feeding Alga 1.0 linearly …

Life Cycle Assessment Of The Us Beef Processing Through Integrated Hybrid Approach, Shaobin Li, Yuwei Qin, Jeyamkondan Subbiah, Bruce Dvorak

Department of Civil and Environmental Engineering: Faculty Publications

Hybrid life cycle assessment (LCA) incorporating process-based and economic input-output (EIO)–based inventory data has been applied in various industries (e.g., wind energy, biofuel). Few hybrid LCA studies have been found in the food industry. This work analyzes the life cycle environmental impacts of the US beef processing industry using process-based and integrated hybrid LCA. The process-based inventory includes all resource inputs and waste outputs associated with a beef processing plant. The EIO-based inventory includes key activities missing in the process-based inventory, such as technical and management service, wood and paper, and industrial equipment. Ten environmental impact categories from TRACI v2.1 …

Sustainability Assessment Of U.S. Beef Processing And Its Antimicrobial Systems, Shaobin Li

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

With the increasing meat demand and awareness of sustainability, concerns have been raised regarding the sustainability of beef production and processing. However, scarce data and inadequate sustainability assessment frameworks for the U.S. beef processing industry limit the ability to develop new technologies and policies comprehensively without shifting sustainability burdens. To fill those gaps, various assessments of the U.S. beef processing industry were conducted from multiple perspectives regarding the environmental, economic, microbial effectiveness of its antimicrobial systems, and human health impacts from foodborne illness, occupational hazards, and environmental pollution.

First, process-level water and energy usage at a typical large-size beef processing …

Using 3d Models And Virtual Reality To Foster Learning Of Carcass Anatomy, Renae Sieck

UCARE Research Products

In meat science and carcass anatomy, an often-debated topic is the methodology educators should follow for effective and efficient learning of carcass anatomy among students. Many traditional learning environments utilize monolithic methods for teaching anatomy that fail to engage students or pedagogically enhance their cognitive development to the fullest potential. Access is also limited because of the need for specialized facilities’ and equipment. We are interested in understanding and measuring the success of learning tools such as Virtual Reality (VR) and 3D Visualization in student learning. Our study’s results would be useful to indicate if student attitudes and student performance …

The Use Of Grape By-Products As A Nutrient Rich Cattle Feed, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

In this article you will learn about how to use the grape stems, skins and pulp that are generated by the wine industry. Ruminant animals such as cattle can digest this inexpensive yet nutrient rich material. The complete process from wine press to cattle feed is covered in this article. The historical background of using grape by-products and methods to preserve this food source is also presented.

Bovine Tuberculosis, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

Tuberculosis affects all species of domestic mammals although with different degrees of intensity and frequency. Cattle and swine furnish the greatest number of cases.
