Desempenho de bovinos simulado pelo modelo Pampa Corte e obtido por experimentação.

This study had the objective to evaluate Pampa Corte Model's reliability in predicting beef cattle performance in grazing systems. For this purpose, model's predicted values were compared to available data base of published papers. Correlation coefficients above 90 % were obtained between simulated and real data in all tested alternatives. Model's data base should be enlarged by forage productivity data in different climatic conditions. Mixtures of Italian ryegrass and oat need more studies to obtain qualitative parameters (crude protein degradability and neutral detergent fiber), as well, animal performance in the single pastures of oat or Italian ryegrass.
