Resumo: 	The Pampa-Corte model was developed to simulate the growth of beef cattle in grazing systems in a dynamic and mechanistic way. It was validated under Brazilian conditions. This paper aims to verify the performance of the model in conventional and alternative beef cattle finishing systems in Spain. An experimental dataset of 21 Parda de Montaña calves of similar age and weight at weaning was used to evaluate the model. They were slaughtered individually on reaching 450kg liveweight. The model considered genetic group maturity rather than breed, in order to adjust growth parameters, once Parda de Montaña breed is not contemplated by AFRC (1993). Parameters from late maturing group were initially used considering adult animal size of Parda de Montaña animals; however, the best fit was with values from the early maturing group. The model predicted accurately animal growth in grazing and conventional finishing systems in Spain, although estimates were less precise when changes in animal management involved physiologic modifications.
