In a trail the Apparent Metabolizable Energy (AME), Apparent Metabolizable Energy corrected to Nitrogen retention (AMEn), True Metabolizable Energy (TME) and True Metabolizable Energy corrected to Nitrogen retention (TMEn) content of some feeding stuffs for poultry were determined with cockerels. The test materials consisted of feed grade Oak (Quercusfaginea), Fig (Ficus carica), Olive (Olea europea) pulp with nucleolus and without nucleolus. The result showed that Oak, Fig, Olive pulp with nucleolus and without nucleolus according to their component can be noticed as an energy sources. Their crude protein was low. The nitrogen- corrected Apparent Metabolizable Energy (AMEn) values for Oak, Fig and Olive pulp with nucleolus and without nucleolus were 2775.04 +/- 29, 2558.7 +/- 35, 1347.05 +/- 64 and 3052.33 +/- 122 Kcal kg(-1) dry matter, respectively. The nitrogen-corrected True Metabolizable Energy (TMEn) value for the respective feeding stuffs were 3177.99 +/- 30, 2999.06 +/- 33, 1537.02 +/- 59 and 3243.34 +/- 126 Kcal kg(-1) dry matter.
