Economic Consequences of Alternative Stocking Rate Adjustment Tactics: A Simulation Approach
Journal of range management
AbstrrCt An economic 8n8Iysis of 8iterMtive stocking r8te adjustment tactics is performed using a simulation model wbicb emuhtea tbe 8nnu8i decision-nuking situ8tion of a rurcber. The model includes vuiation in livestock priccs 8nd 8nnu8i forage production. Tbe muuger's decisions 8re b8sed on tbe 8v8ii8biiity of fonge 8t 4 de&ion points in tbe yeru, tbe expected growtb between the current decision point md tbe next, md tbe expected portion of tbe fonge tb8t is to be b8rvested tbrougb gr8zing.
