AIM: establishing of the net transformation of the energy and the protein in the eco-technical chain “fodder-egg mélange” by replacement of the 10% of the grain component of the combined fodder for Guinea fowls – layers with bread wastes.MATERIAL AND METHODS: 2 groups – control (without bread wastes) and experimental – 10% replacement of wheat with bread wastes.RESULTS: For the Clarc of energy distribution (ME fodder-GE egg mélange) – control group – 0.1410, with 10% bread wastes – 0.1415; for the Clarc of protein transformation (CPfodder-CP mélange) – respectively 0.1654 and 0.1720. For both of the indexes the bird consumed 10% bread wastes have significant higher energy and protein net utilization.
