Using methods for balance experiments, the apparent (AMEn), the true (TMEn) metabolizable energy (0-n balance corrected) and the coefficient of true digestibility of the nitrogen/protein (CTDP) of extruded bread wastes have been studied. The chemical composition of the dry matter of the fodder was, as follow (in %): crude protein – 12.28; crude fats – 1.34; crude fiber – 2.28; NPE – 80.1. The following energy/protein levels in the DM have been established: (AMEn – 14.17 MJ/kg; TMEn – 15.37 MJ/kg; CTDP - 84.15. The established nutritional values are similar to those of wheat, both fodders can be replaced each other in the production of compound feed for poultry.
