Experiments have been carried out on the effect of gamma irradiation on total energy, dry organic matter digestibility and on digestible energy of organic matter for some agricultural residues (maize straw, lentils straw, cottonwood, residues of apple-tree pruning, olive-cake first and second treatment). Samples were irradiated at 0, 50 and 100Kgy. Total energy was estimated by calorimeter. Digestibility was estimated in vitro by the method of Tilly and Terry (1963). Two sheep with rumen festula were used as rumen liguor donating animals. Irradiation resulted in increasing the digestion of organic and dry matter and also the digestible energy of organic matter in all residues used except lentils straw and olive-cake first treatment. The increase in digestible energy values of organic matter (kj) at dose of 100 Kgy were: 155, 105, 71 and 25 for residue of apple-tree pruning. Maize straw, cottonwood and olive-cake second treatment, respectively.
