Development of Forage Nutrient Value Coefficients for Use in CARD's 1985 RCA Model, The
为CARD/RCA模型的畜牧业部门开发了牧草养分价值系数，涵盖净能、蛋白质、钙和磷，用于31个市场区域的饲料转移活动，对模型改进和农业政策分析有用。
After preliminary work on the livestock sector for the 1985 CARD/RCA model was completed in the summer of 1983, it was felt that one of the weaker areas in the sector was the linkage between the livestock sector and the range sector. At that time it was decided that the best way to approach this problem would be through the development of feed transfer activities.\nThe purpose of this paper is to present a brief overview of the development of the nutrient value coefficients for net energy, protein, calcium, and phosphorus supplied by grazed forages in the 31 market regions. The data developed in this paper serves as coefficients for feed transfer activities in the livestock sector of the CARD/RCA model.
