INTRODUCTION THE greatest part of the cost of a balanced poultry diet is incurred in providing energy. To discover the relative economy of using different energy sources an accurate and valid energetic evaluation system of poultry feeds is essential to compose the most economical rations. In modern poultry feed formulation, where an increasing demand is made on linear programming techniques, the exact knowledge of the available energy content is of considerable importance, because the inclusion or rejection of a particular feeding stuff in the least-cost ration is greatly dependent on the used energy values. The widespread use of an energetic evaluation system, based on reported metabolizable energy (M.E.) values, has resulted from the fact, that the determination is relatively simpler and more accurate compared to net (productive) energy values (N.E.) and that the influence of feed intake, growth rate, age, breed, sex and nutrient balance is small and not of…
