Abstract
The article presents the results of direct research on livestock buildings and their modernization in selected ecological farms in the Lublin region. The following counties of the Lublin Voivodeship were selected as the research area: Radzyń and Łuków. A total of livestock buildings in 16 farms were examined. The research was conducted based on a site visit and discussions with the owners. An attempt was made to find a relationship between ecological livestock farming and a building substance (livestock buildings).
