Potential meat production from irrigated ryegrass white clover pastures was evaluated during three growing seasons (1979-1982). A 4 ha area splitted in 8 plots of 0.5 ha each, and fertilized with 48 kg of N, 26,2 kg of P and 25 kg of K/ha per year was used. Meat production was evaluated by using "Overo Negro" young bulls of 209-258 kg initial live weight kept on a rotational grazing system. The stocking rate was adjusted according to grass allowance and the animal were taken out of the trial when a live weight of about 428 kg was reached. With this king of pasture plus a mineral supply it is possible to get a net live weight gain of 1,000-1,200 kg/ha, with an average gain of 3.9 kg/ha/day, and stocking rates of 2.8-3.7 animal units/ha. According to these results and the potential milk production evaluated on the same king of pastures, a relationship between potential milk and meat production of 11.9 to 13.7: 1 can be estimated
