Adult female chickens were force-fed a corn-soy base diet at 150% of the daily amount consumed by those allowed the same diet ad libitum. Other hens were force-fed diets isocaloric to the 150% group just mentioned, but diet composition was adjusted so that 2/3 of the metabolizable energy (M.E.) came from the corn-soy diet and 1/3 from either corn oil or glucose; or force-fed a low energy diet accounting for 2/3 of the M.E. and corn oil 1/3 of M.E., or a purified diet accounting for all M.E. Fatty liver-hemorrhagic syndrome (FLHS) was induced in all force-fed groups with only the low energy diet plus corn oil having produced a significantly lower score for FLHS. However, the livers from the hens of the latter group had as much lipid, and the hens gained at least as much weight as those in other force-fed groups. During the third week of the experiment M.E. was determined along with a partition of energy among eggs, basal metabolism, body weight gain, and subsistance plus heat increment (H.I). The data showed that the hens force-fed corn oil had lower H.I. values indicative of associative dynamic action of fats at a plane of nutrition above normal. The data revealed that various types of diets and sources of energy in excess can induce FLHS, and this is discussed in terms of FLHS arising out of a positive energy balance.
成年雌性鸡被强制喂食以玉米 - 大豆为基础的日粮，喂食量为自由采食相同日粮的鸡每日摄入量的150%。其他母鸡被强制喂食与上述150%组等热量的日粮，但调整日粮组成，使2/3的代谢能（M.E.）来自玉米 - 大豆日粮，1/3来自玉米油或葡萄糖；或者被强制喂食占M.E. 2/3的低能量日粮和占M.E. 1/3的玉米油，或者一种占所有M.E.的纯化日粮。所有强制喂食组均诱发了脂肪肝出血综合征（FLHS），只有低能量日粮加玉米油组的FLHS评分显著较低。然而，后一组母鸡的肝脏脂质含量与其他强制喂食组相同，且体重增加至少与其他组相当。在实验的第三周，测定了M.E.以及能量在鸡蛋、基础代谢、体重增加和维持加热增耗（H.I.）之间的分配情况。数据显示，被强制喂食玉米油的母鸡H.I.值较低，表明在高于正常营养水平时脂肪具有协同动态作用。数据表明，各种类型的日粮和过量的能量来源均可诱发FLHS，并从正能量平衡导致FLHS的角度对此进行了讨论。
