Abstract

This study evaluates the sustainability of a rabbit production system using the Emergetic Synthesis methodology, which integrates energy, material, and economic service, flows into a single unit (emjoule or sej). The research was conducted on a rabbit production system established at the "El Guayabal" University Farm, belonging to the Agrarian University of Havana (UNAH). The analysis considered the production closing period of 2025, with data extending into January 2026. An initial herd of 100 rabbits and a final herd of 239 rabbits were analyzed, fed a specific diet and receiving basic health management. Traditional emergetic indices (Transformability, Energy Performance Ratio, Environmental Load Ratio, and Emergetic Sustainability Index) were calculated and analyzed, as well as economic indicators (Net Income, Total Cost, Net Benefit, and Benefit/Cost Ratio). The results indicate that the system exhibits efficiency in the use of local renewable resources, with moderate transformation and a low environmental impact, reflecting acceptable sustainability but with room for improvement. Economically, the system showed profitability. These results demonstrate that Emergetic Synthesis is a robust tool for diagnosing the overall sustainability of rabbit production systems, recommending the optimization of non-renewable input use and the strengthening of food self-sufficiency.
