An experiment was made with adult, S.C.W.L. roosters to measure the effect of the duration of the starvation period, prior to force feeding, on the true metabolizable energy (T.M.E.) value of a laying hen diet. Lengthening the starvation period from 24 to 96 hr., by 24 hr. intervals, had no significant effect on the T.M.E. value. The excretion of metabolic fecal + endogenous urinary energy per day tended to decrease with the duration of starvation. It is therefore, essential that the duration of the starvation period is identical for control and force fed birds. It is also essential that the duration of the experimental period is identical for both groups of birds.
对成年的S.C.W.L.公鸡进行了一项实验，以测定强制喂食前饥饿期的时长对蛋鸡日粮真代谢能（T.M.E.）值的影响。将饥饿期从24小时延长至96小时，每次延长24小时，对T.M.E.值没有显著影响。每天代谢性粪便+内源性尿能的排泄量往往会随着饥饿期的延长而减少。因此，至关重要的是，对照组和强制喂食组鸡的饥饿期时长要相同。同样重要的是，两组鸡的实验期时长要相同。
