anglais. In the tropical region central of Minas Gerais State, integrated crop-livestock systems are characterized by annual rotation or succession of crops and pastures in a no-till system in which the pasture is used to produce either milk or meat. In this paper the system focus on integration of maize and sorghum in consortium with Urochloa and Megathyrsus maximus, respectively, for silage, followed by pasture were Nellore and 1/2 Nellore: Angus calves remain for one year, and then soybean is cultivated in no-till system. The green and dry biomass production, in t/ha, of grass forage cultivar ?Tanzânia-1? or ?Mombaça? are presented in annually data before and after stocking in rotated management during wet and transition seasons. The calves body weight gains recorded in these years of integrated crop-livestock system are above the average of Brazilian productivity. In average, the annual animal productivity was of 1,281 kg of live weight per hectare. In conclusion, the integrated systems in region provide the opportunity for intensification with sustainability.
