Results from this research work deal with some studies on energy working performed in 20 farms from La Palma municipality, Pinar del Rio. The following indicators were evaluated: energy production, protein production, amount of persons that can be fed by the farm considering energy and protein requirements, as well as input energy/output energy unit ratio. Data and calculations were recorded by means of Energía software. Thus, it was concluded that energy balance in those farms is mainly affected by external inputs supplied for animal production purposes. Such inputs correspond to food concentrates used for pig breeding in most cases, whereas inputs applied to crops are not significant factors, since they are used in tiny proportions.

Palabras clave : energy balance; energy generation; production; protein.
