确定畜禽动物最佳售卖期的数学方法及其应用研究

本文从畜禽动物的生产能力和饲料消耗两个基本要素出发,通过建立投入产出经济效益函数关系式Z(T)=W(T)-G(T)-R,利用极值理论对最佳停止饲养时间的确定进行了研究。文中以肉用商品鸡为例,讨论了数学模型的建立,研究过程中的方法与步骤,对所取得的结果进行了动态技术经济分析。本研究中所采用的数学方法具有普遍的意义。即不仅适用于不同类别、不同品种畜禽动物最佳售卖期的确定,对于凡具有生物学生长特性的类础研究,都可利用相同方法求出以经济效益最大为目标的最优解。这种方法的应用推广,对于指导养殖业的经营决策,促进畜牧业的发展必将起到积极的作用。

Study on the Mathematical Method of the Optimal Selling Occassion of Domestic Animal and it''''s Application

Proceeding from the two besic factors about productivity and consumption. This paper has determined the optimal occassion of stopping feed of domastic animals useing extremum theory through establishing functional residues equation of economic benifit of the input and output: Z(T)=W(T)-G(T)-R. In the paper, themeat poltry has heen exampled, the author has discussed the methods and steps of establishment of mathematic model and has analysed the results useing method of dynamic technical economies. The mathermatics mathod in the paper is of universal sgnificance, which not only can be used for determining the optimal selling oecassion of domestic animal of different types and breeds, but can be used for the other similar studies of having biological growth characters, The useing and spread of the study result will play an active affect for guiding the management policy of livestock breedinng and promoting development of livestock industry.
