“…Marginal economic production of any factor could be realized, when the cost factor is equal to product price. The results of this research are compatible with explanations about functional analysis of production given by other researchers (Doll et al, 1968;Heady, 1968;Cramer et al, 1979).…”

Using mathematical methods and statistical techniques, the present paper explains the current economic characterization of broiler meat production under the economic conditions of Turkey. State of the art of econometrical modelling and the classic method currently used for regulatory decisionmaking in the world are described. Based on this evaluation, needs for future research are defined. It is concluded from our work that mathematical modelling of economically optimal production time would improve economic profitability. The classical method of economic optimization in animal production would not be suitable for all kinds of economic assessments, and that a range of different approaches is necessary so that the method used is the most appropriate for the data available and for the economic risk characterization issue. Future refinements to classical evaluation should incorporate more clearly the extent of uncertainity and variability in the resulting output. In this study, the basic data used for evaluation were food intake, weight gain, food cost, cumulative weight gain, cumulative chicken cost and marginal net income (MNI). After the mathematical function between production period and MNI was calculated, the optimum production period was predicted. Then, total MNI was estimated by integration of the calculated mathematical function.

“…Then, total marginal income (TMI), total marginal food plus cumulative chicken costs (TMC), total marginal net income (TMNI), marginal food conversion ratio cost plus marginal chicken cost (MC) and coefficient of economic efficiency (CEE) per chicken for each period were calculated. The coefficient of economic efficiency (CEE) is calculated as follows: CEE = Total marginal net income / Marginal costs (Heady, 1968).…”

The present paper uses mathematical methods and presently available statistical techniques to economically characterize broiler meat production under the economic conditions of Turkey. State-of-the-art econometric modelling and classic methods used currently for regulatory decision-making in the world are described. Based on this evaluation, needs for future research are defined. It is concluded from our work that mathematical modelling of the economically optimal production time using the coefficient of economic efficiency would improve economic profitability. The classical method of economic optimization in animal production is not suitable for all kinds of economic assessments. A range of different approaches is necessary so that the method used is the most appropriate for the data available and for the economic risk characterization issue. In the present study, the basic data used for evaluation were: total marginal income, total marginal food plus cumulative chicken cost, total marginal net income, marginal food conversion ratio cost plus marginal chicken cost, and the coefficient of economic efficiency. After the mathematical function between production period and coefficient of economic efficiency was calculated, the optimum production period was predicted. Then, the total coefficient of economic efficiency was estimated by integration of the calculated mathematical function.
