INDICADORES ECONÔMICOS E VIABILIDADE FINANCEIRA DE NOVILHAS DE CORTE SUPLEMENTADAS À PASTO NO PERÍODO DAS ÁGUAS EM COMBINADO – TO

Abstract

This study aimed to evaluate the phenotypic, zootechnical, and economic performance of Nelore heifers subjected to three different supplementation strategies during the rainy season in Combinado–TO, Brazil. A total of 54 heifers were used, divided into three groups of 18 animals each: Group A (mineral salt supplementation), Group B (protein supplement – Blond 200), and Group C (protein-energy supplement – Total Diet). The evaluation lasted 45 days and included assessments of body condition score, muscle conformation, coat quality, and economic indicators such as cost per arroba, profit margin, and return on investment. The results showed that Group C achieved the highest phenotypic and productive gains, though at a higher operational cost. Group A demonstrated the best economic performance, with greater profitability and cost-benefit. Group B had intermediate results in all parameters. Overall, the findings suggest that more complex supplementation strategies do not necessarily yield higher profitability. Nutritional planning should be aligned with the economic context of the farm to ensure both zootechnical efficiency and financial sustainability.
