Subject. This article explores the theoretical basis of the economic efficiency of production and classifies the performance figures of beef cattle husbandry. Objectives. The article aims to define a system of indicators of beef cattle husbandry economic efficiency. Methods. For the study, we used a comparative analysis. Conclusions and Relevance. To assess the economic efficiency of agriculture production, it is necessary to use a set of indicators by beef cattle breeding sub-sector. The system of economic performance indicators of production needs to be transformed into a summarizing indicator.
