Resumen:
The Global Climate Change is one of the most important environmental problem in this
century. This problem has increased with the intensification of greenhouse gas emissions (GGE),
causing higher levels of gases such as methane (CH4) in the atmosphere. The major challenge in the
regions with high concentration of animal production is reaching the energetic and environmental
sustainability, as well as reducing the GGE. The energetic aspect is increasingly in importance in
swine and poultry production. Recently, the search for alternative energies has been motivated by
successive energetic crisis, global warning and high prices of petrol. The anaerobic digestion in
biodigestors (biomethanization), consists in a complex mix of microorganisms that have the capability
of convert organic materials, such as carbohydrates, lipids and proteins into methane and carbon
dioxide. Probably, this process is the most economically feasible alternative to convert swine manure
into thermal energy. Methane generated in biodigestor is a renewable source of energy that can
substitute fossil fuels, such as buthane and wood for warming internal environments in poultry
buildings.
