A DETERMINISTIC MODEL FOR THE ECONOMIC-EVALUATION OF BROILER PRODUCTION SYSTEMS

A deterministic model for the economic evaluation of broiler productio n and the derivation of economic values in broiler breeding was develo ped and tested. The model distinguishes four production stages: multip lier breeder, hatchery, commercial grower, and processor. The processo r is included to determine relationships for the price per kilogram of live weight and the quality of the carcass, either on a ''whole sale' ' Or ''further processed'' base. Quantity of product output for the sy stem is fixed by a predetermined amount of kilogram carcass of final p roduct broilers finished by the commercial grower. Profitability of pr oduction and cost prices per unit product for subsequent stages can be calculated. Exogenous parameters are easily changeable in oi;der to c alculate profitability and cost prices for different production levels or production circumstances. Economic values can be derived consideri ng influences Of changes in genetic merit for performance traits on pr ofitability or cost price, for integrated and nonintegrated production systems. By changing exogenous parameters, the model can also be used to analyze profitability or derive economic values for other meat-typ e poultry, such as turkey.
