BALTIERRA-TREJO, Eduardo; ARROYO-PITACUA, Alejandra  e  MARQUEZ-BENAVIDES, Liliana. Energy analysis and CO₂ eq emissions of chicken meat production. Ecosistemas y recur. agropecuarios [online]. 2017, vol.4, n.12, pp.571-577. ISSN 2007-901X.  https://doi.org/10.19136/era.a4n12.1093.

In México, greenhouse gas emissions from the agricultural sector include mainly enteric and manure sources. However, emissions due to the use of fossil energy are usually not considered. The aim of this work was to identify the energy demand (MJ) to produce a kilogram of chicken meat, and to determine the associated CO2 equivalent emissions. To that end, a farm in west-central Mexico was studied to profile the energy demand to supply water, feed, lighting, ventilation, air extraction and heating, using 1000 birds as a calculation basis. It was found that the emissions derived from fossil energy use were 0.47 kgCO2 eq per kilogram of live weight per production cycle.
