A static deterministic model was used to evaluate productivity and efficiency of growing and finishing beef steers systems in Rio Grande do Sul State differing at steers slaughter age (IA): 54, 42, 36, 30, 24 and 18 months (IA54, IA42, IA36, IA30, IA24 e IA18, respectively), or in market live weight for buying and sale (cattle growing systems from 150 to 250 kg -R1, from 250 to 350 kg -R2, or finishing cattle from 350 to 450 kg -R3).
