Abstract

Methane produced by ruminants is considered twenty times more potent than carbon dioxide (CO2) in the process of the greenhouse effect and increasing the concentration of these gases are responsible for global warming. To implement mitigation strategies, it is important to have confidence in the accuracy of measurement technology CH4. Methane emissions from livestock were measured as part of studies on ruminal fermentation, energy balance, evaluation of feed additives and, more recently, to characterize and reduce the contribution of ruminants to global CH4 emissions. However, it is of great importance to the study on the production of methane produced by ruminants, as well as providing the energy consumption for production, it also becomes important to determine nutritional strategies that enable reduction of emissions of this gas into the atmosphere (Bhatta et al, 2007). In this light the internship abroad has as main objective to evaluate other methods of methane production, as well as exploring the results found in experiment. Moreover, improving the final discussion of the results of the work, and offer the opportunity to students to learn different techniques related to their dissertation work. The stage will be developed at the research center Rural Research, Education & Consulting (SRUC), located in Scotland. In the first month of training, the fellow will present the data generated in the experiment Master Professor Tony Waterhouse, and together, discuss them. Also at that time will follow a field experiment of greenhouse gases in systems of cattle and sheep. The second month will be devoted to writing the scientific paper containing the data of the dissertation (Project FAPESP (2011/14842-8), as well as assessment of CH4 production techniques, thereby strengthen interagency collaboration and will provide greater enhancement of the dissertation, extending the discussion, thus optimizing the quality of it.
