COMPARATIVE EVALUATION OF GRAZING SYSTEMS IN BEEF CATTLE FARMING: AN ECONOMIC, FINANCIAL AND YIELD ANALYSIS

livestock; integrated management; profitability; productivity.

The economic and financial review of beef cattle farming is a critical factor for the success and sustainability of this agricultural activity. Producers who implement integrated management practices are better positioned to face challenges and seize opportunities in the market. In this context, the objective was to analyze the economic, financial and productivity perspectives of the rotational and conventional grazing system under rainfed regime, installed with Brachiaria brizantha cv. Marandu in beef cattle farming, on a medium-sized rural property, located in the extreme south of Bahia. The data was collected from July to 2023 to May 2024, using zootechnical, financial and economic data for subsequent analysis of result indicators in the evaluation of profitability and productivity using the indices: GMD, Cash Flow, IRR, TMA, NPV and Payback with rate Selic of 13.25% p.a. Based on the results obtained, the implementation of the rotational grazing system proved to be viable both economically and financially, revealing a positive Net Present Value (NPV), which is a favorable indication. The Internal Rate of Return (IRR) exceeds the discount rate (13.25%), which points to an attractive rate of return. Furthermore, the investment recovery period measured by Payback is relatively short, suggesting that the owner has the possibility of recovering his initial investment within a time interval of 2.37 years. The rotated system provided more efficient production, with a greater yield of arrobas per hectare. The average daily gain (ADG) achieved was 0.633 kg day-1 in the rotational grazing system and 0.548 kg day-1 in the conventional system. This reflected statistically significant differences between the two management methods. This work becomes relevant by enabling integration between the academic environment and the agricultural sector, providing feedback to interested parties through the results obtained.
