A deterministic model for the economic evaluation of broiler production and the derivation of economic values in broiler breeding was developed and tested. The model distinguishes four production stages: multiplier breeder, hatchery, commercial grower, and processor. The processor 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 system is fixed by a predetermined amount of kilogram carcass of final product broilers finished by the commercial grower. Profitability of production and cost prices per unit product for subsequent stages can be calculated. Exogenous parameters are easily changeable in order to calculate profitability and cost prices for different production levels or production circumstances. Economic values can be derived considering influences of changes in genetic merit for performance traits on profitability 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-type poultry, such as turkey.
开发并测试了一个用于肉鸡生产经济评估和肉鸡育种经济价值推导的确定性模型。该模型区分了四个生产阶段:曾祖代种鸡、孵化场、商品肉鸡养殖户和加工商。纳入加工商是为了确定每千克活重价格与屠体品质之间在“批发”或“深加工”基础上的关系。系统的产品产出量由商品肉鸡养殖户完成的最终产品肉鸡预定的千克屠体量确定。可以计算后续阶段的生产盈利能力和单位产品成本价格。外生参数易于更改,以便计算不同生产水平或生产情况的盈利能力和成本价格。考虑性能性状遗传价值变化对综合和非综合生产系统盈利能力或成本价格的影响,可以推导出经济价值。通过改变外生参数,该模型还可用于分析其他肉用家禽(如火鸡)的盈利能力或推导其经济价值。
