Optimum slaughtering time in temporal deer farming in Japan

The purpose of this paper is to examine the most appropriate slaughtering time for deer from an economic perspective under the following conditions: (1) standard deer farming and temporal deer farming; (2) unit price of venison is constant and is a function of age in months (3) grazing and pen feeding. Based on numerical analysis, the optimum slaughtering times are 30 and 31 months when price is constant and 17 and 18 month when price is a function of age in months. Our results suggest that temporal deer farming with pen feeding is not realistic and grazing should be selected.
