The relationship between the protein content of feedstuffs and the magnitude of difference between corresponding true metabolizable energy (TME) and nitrogen-corrected TME ( TMEn ) was investigated. Fifty-two samples of feed ingredients, mixtures of ingredients, and mixed feeds were assayed for TME and TMEn . A positive relationship was observed between the protein content of the feed samples and the magnitude of difference between determined TME and TMEn values. The regression equation describing this relationship is Y = . 122X + 3.724, where X equals percent protein and Y the percent difference between TME and TMEn . The corresponding r2 was .60.
研究了饲料原料的蛋白质含量与相应的真代谢能（TME）和氮校正真代谢能（TMEn）之间差异大小的关系。对52个饲料原料、原料混合物和配合饲料样本进行了TME和TMEn测定。观察到饲料样本的蛋白质含量与所测定的TME和TMEn值之间的差异大小呈正相关。描述这种关系的回归方程为Y = 0.122X + 3.724，其中X为蛋白质百分比，Y为TME和TMEn之间的差异百分比。相应的r2为0.60。
