In 12 experiments with S.C.W.L. roosters it was shown that for each of 12 feedingstuffs there was a linear relationship between feed input and the amount of energy voided as excreta. In the 24 h. period, following 21 hr. of starvation, roosters receiving no feed excreted 4.07 kcal./kg. of body weight. When dextrose was fed the energy voided as excreta did not increase with dextrose input; consequently, the true metabolizable energy (T.M.E.) value of dextrose is its gross energy value. The T.M.E. values were not affected by the level of feed input and appeared to be additive. A simple, rapid assay for T.M.E. was developed, based on gross energy assays of the test feed and of excreta voided over 24 hr. by roosters force fed the test feed and other starved over the same period.
在对S.C.W.L. 公鸡进行的12次实验中发现，对于12种饲料中的每一种，饲料摄入量与作为排泄物排出的能量之间都存在线性关系。在饥饿21小时后的24小时期间，未进食的公鸡每千克体重排泄4.07千卡能量。当喂食葡萄糖时，作为排泄物排出的能量不会随着葡萄糖摄入量的增加而增加；因此，葡萄糖的真代谢能（T.M.E.）值就是其总能值。T.M.E. 值不受饲料摄入量水平的影响，并且似乎具有可加性。基于对测试饲料以及强制喂食测试饲料的公鸡在24小时内排出的排泄物和同期饥饿公鸡排出的排泄物进行总能测定，开发了一种简单、快速的T.M.E. 测定方法。
