The present study was conducted to determine the nutritive value and estimation metabolizable energy and organic matter digestibility of some food industrial by-products with gas production method. In this experiment three canulated steers (Holestein) were used. The amount of gas production for feedstuffs at 0, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours were measured. The food industrial by-products that used in this study include: grape marc, apple pomace, tomato pomace, beet pulp, pomagranate seed pulp and pomagranate peel. The results showed that the Crude Fiber (CF) contents of apple pomace, white grape marc, pomagranate seed pulp, pomagranate peel, beet pulp and tomato pomace were 32.8, 22.8, 32.3, 15.1, 24.8 and 32.4 % and gas production for feedstuffs at 24 hours were 58.92, 30.92, 47.42, 22.92, 78.02 and 39.38, respectively. The organic matter digestibility (OMD) (%) in beet pulp was higher than another pulps.The Metabolizable Energy (ME) contents of beet pulp, apple pomace, tomato pomace, pomagranate peel, white grape marc and pomagranate seed pulp were 13.8, 10.73, 9.06, 8.85, 7.4 and 6.2 MJ kg-1 DM, respectively.
