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.]]></p></abstract>

Con el objetivo de conocer la demanda energética (MJ) para producir un kilogramo de carne de pollo y determinar la emisión de CO2 equivalente asociada, se analizó el consumo energético necesario para el suministro de agua, alimento, iluminación, ventilación, extracción de aire y calefacción en una granja, tomando como base de cálculo 1000 aves. Se determinó que la emisión derivada del consumo de energía fósil fue de 0.47 kg CO2 eq por kilogramo de carne de pollo en pie en un ciclo productivo.]]></p></abstract>
