Department of Animal Science: Dissertations, Theses, and Student Research
Interest in reducing methane (CH4) emissions by cattle has increased recently. Loss of feed energy as CH4 represents both an environmental concern and an energetic loss to the animal. Manipulation of dietary composition has proven to be an effective mitigation strategy. Experiments were conducted to evaluate the effect of several dietary characteristics on CH4 production in growing and finishing cattle, and to develop a novel, non-invasive method for quantifying emissions from animals in a production setting. Short-term gaseous emissions of CH4 and carbon dioxide (CO2) were measured and the CH4:CO2 …
