数学公式法评估饲料原料的适宜价格

Assessment of the Appropriate Price of Feed Raw Materials by Using Mathematical Formula Method

配合饲料中使用量最大的是能量与蛋白质原料,决定其价格的关键因素是可利用能值和蛋白质含量及品质。将原料价格分解为可利用能值、蛋白质含量和蛋白质品质3个部分。选用GB2级玉米、GB/T2级豆粕、合成蛋氨酸和赖氨酸做参照物,以此为基础计算饲料原料的的蛋白质价格、可利用能值价格、蛋白质品质价格,三者之和即为饲料原料的适宜价格。该计算公式可用于评价原料的适宜价格,若原料的适宜价格大于市场价格说明该种原料与参照物相比,可节省成本;反之成本增加,使用该原料经济上不合算。

The largest amount of feed is energy and protein raw materials,the key factors influencing price are valuable emergy,protein content and quality.The price of the raw material is composition of available energy value,protein content and protein quality.Selection of GB2 grade corn,GB/T2 grade soybean meal,corn synthesis of methionine and lysine as reference for the calculation of feed raw materials prices of the protein,available energy value and protein quality.The sum of the three is the appropriate price of feed raw materials.The formula can be used to evaluate the appropriate prices of raw materials,if the price is greater than the market price for the raw materials,the cost can be saved;or else the cost can be increased.
