Abstract: Due to rising trend of imported beef from abroad in Malaysia, it is necessary to find out the source of economic beef production with lower government investment cost for beef importation (GICI). In this study, system simulation modeling and cost-benefit analysis have been used. The result showed 5-7% slaughter rate of female breeding stock (FBS) is economic and more effective input for beef production as well as for government investment cost for importation. However, average 58% self-sufficiency rate for beef can be achieved in future at 5-7% slaughter rate, 75-80% calving rate, 1-2% mortality rate.
