Abstract. State aid for the implementation of voluntary commitments for human attitude toward pigs involves providing artificial light for 11 hours a day. This technological approach is associated with a further increase of energy consumption at farms. Therefore, relevant calculation methods for determination of the energy costs of providing artificial illumination by various types of lighting fixtures are proposed. This comparative analysis can be used by farmers to optimize the energy consumption in different categories of pigs.
