Sistema Voisin, established in 1957, is a pioneering method of pasture and herd management that emphasizes agroecological principles to create a harmonious balance among soil, pasture, and livestock. Introduced to Brazil in 1963, the system is noted for its innovative use of rotational grazing methods, allowing for sustainable livestock farming practices where cattle can achieve higher weight gain and milk production. This technique enables farmers to maintain a greater number of animals per area than traditional pasturing methods, thus increasing their profitability.

Under the guidance of André Voisin, who developed the method, Sistema Voisin has attracted attention from farmers and agricultural students worldwide, leading to its widespread adoption across Brazil. Today, the system is employed across various ecosystems, from southern pampas to the arid regions of the Northeast, adapting to diverse climatic conditions and enabling effective management of bovines, bubalines, ovines, and caprines. The continuous evolution of this method represents a significant advancement in sustainable agricultural practices.
