1.测定了玉米、葵花粕和豆粕三种原料的代谢能值(AME、AME(N)、TME(N)和TME(N))在两种经典饲喂技术(自由采食和强制饲喂干饲料)和一种新的强制饲喂湿饲料的条件下，对成年公鸡进行了测定。在湿强迫喂食法中，氮平衡和食物摄入量与自由喂食法相似。与干法和随机法分别需要3天和7天的试验期相比，采用湿法强制饲喂的测定持续时间仅为2天。TME(N)值不依赖于所使用的喂养技术；在自由和湿强迫喂食试验中获得的AME和AME(N)数据与TME(N)值接近。正如预期的那样，在干力喂养试验中，这些值被低估了。
1. Metabolisable energy values (AME, AME(n), TME and TME(n)) of three raw materials (maize, sunflower meal and soyabean meal) were determined in adult cockerels using two classical feeding techniques (ad libitum and force-feeding of dry food) and a new one in which birds were force-fed wet diets.2. In the wet force-feeding assay nitrogen balances and food intakes were similar to those achieved with ad libitum feeding. The duration of the assay using wet force-feeding was only 2 d as compared to the 3 or 7 d experimental periods for the dry or the ad libitum assays respectively.3. TME(n) values were not dependent on the feeding technique used; AME and AME(n) data obtained in the ad libitum and wet force-feeding assays were close to TME(n) values. As expected, these values were underestimated in the dry force-feeding assay.
