通过市场上奶牛精料常规原料价格,计算出每单位奶牛能量单位（NND）和粗蛋白质（CP）的平均价格。根据饲料原料中的NND和CP含量,可计算出各种饲料的比较值,即精确得到精料原料的比较价格。在充分考虑原料适口性、可得性及有无毒性等前提因素下,选择低成本的原料配制奶牛精料补充料,可降低饲料配方成本,提高奶牛养殖效益。

Different feed ingredients utilized to compose a dairy concentrate have different prices which depend largely upon their available energy and crude protein. In this paper, NND （dairy energy unit） and CP （crude protein） were used to estimate the shadow or relative prices of the major feed parts of the concentrate, such as SBM, cotton seed meal, corn, wheat （or its bran） and so forth based on their DM （dry matter）, which made it possible to form a relative low cost concentrate by offering a basis to choose them combined with the consideration of their digestability, availability and even the hazardous substances in them.
