Abstract

The relationship between the environment and living beings is highlighted in the social and scientific due to climate change, natural disasters, depletion of natural resources, in addition, there is concern in offering alternatives to ensure the well-being and animal, and increase production. One of the main gases that exacerbate global warming is methane (CH4) and the largest emissions of this gas in Brazil comes from the agricultural sector, cattle being the largest contributor to this statistic, since the country has the world's largest. The scientific contributions related to the release of methane from the respiratory system in cattle associated with latent metabolic heat production is negligible, but also work in this area do not relate these variables with the thermal conditions of the environment. In addition to the CH4 be overlooked in the design of metabolic heat production, the vast majority of this work was performed on controlled environmental conditions and protected from direct sunlight, inside chambers, and located in temperate environment. Therefore it is of great importance to realization of this project under natural conditions in living animals as well, will assess the changes caused by meteorological variables in the metabolism, production and release of CH4. Thus, it is clear the importance of scientific research in this area measuring the emission of CH4, involving the determination of metabolic heat production in order to develop models to predict and colorimetric and interrelated factors, such as animal diet, environmental conditions and thermal zootechnical production.
