A total of 110 barrows fed varying levels of energy and amino acids in 8 treatments, were tested. The weight gains per fattening day and energy expenditure were found to be mainly determined by energy intake. Up to a liveweight of 100 kg both low and high levels of amino acid supply produced the same fattening performance results as amino acid supply to standard. In the 100-120 kg liveweight range, the animals fed higher levels of protein proved slightly superior. As to energy expenditure, animals subjected to restricted feeding up to 70 kg liveweight and fed full rations later, consumed 2.22 kEFs (2.22 kilo energetic feed equivalents/swine) per kg gain and proved significantly superior to those animals that were very intensively fed at the beginning and put to restricted feeding beyond 70 kg liveweight (2.53 kEFs per kg gain) as well as to those receiving high levels of energy all the time (2.39 kEFs/kg gain). In the latter case, 23 g of lysine were required per kg gain.
共测试了110头公猪，这些公猪被分为8种处理方式，饲喂不同水平的能量和氨基酸。发现每育肥日的体重增加和能量消耗主要由能量摄入量决定。在体重达到100千克之前，低水平和高水平的氨基酸供应产生的育肥性能结果与标准氨基酸供应相同。在100 - 120千克体重范围内，饲喂较高水平蛋白质的动物表现略优。至于能量消耗，体重达到70千克之前限制饲喂、之后喂足定量的动物，每千克增重消耗2.22千能量饲料当量（2.22千卡能量饲料当量/猪），并且明显优于那些一开始大量饲喂、70千克体重之后限制饲喂的动物（每千克增重2.53千能量饲料当量）以及那些一直接受高水平能量的动物（每千克增重2.39千能量饲料当量）。在后一种情况下，每千克增重需要23克赖氨酸。
