title: Effect of feeding technique, ad libitum, dry or wet force feeding, on the metabolisable energy values of raw materials for poultry.
abstract: 1. Metabolisable energy values (AME, AMEn, TME and TMEn) of three raw materials (maize, sunflower meal and soyabean meal) were determined in adult cockerels using two classical feeding e 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. TMEn values were not dependent on the feeding technique used; AME and AMEn data obtained in the ad libitum and wet force-feeding assays were close to TMEn values. As expected, these values were underestimated in the dry force-feeding assay.
