Based on the official statistics of industries and mines organization about 2700 ton of waste of spagetti, pasta producing plants, and about 7500 tons of waste in chickpea pre-cleaning plants are produced annually in the E. Azarbaijan province. In order to determine chemical composition and metabolizable energy of the above mentioned waste, first classified random sampling from 10% of plants was performed. Then amount of dry matter, crude protein, crude fiber, ether extract, NDF, ADF, and gross energy were measured according of AOAC (1990) procedures. The amount of crude protein for biscuit, crisp, soup pasta, spagetti, rice pasta, chickpea pre-cleaning and chickpea screening were, 9, 9/2, 14/1, 12/7, 14/5, 30/2, and 30 percent respectively. The wastes of soup pasta, rice pasta, crisp, biscuit, pre-cleaning chickpea, and chickpea screening were mixed on the ratio of 15% to 85% basal diet. The wastw of pre-cleaning chickpea was mixed on the ratio of 15% and 45% to basal diet. The waste ofspagetti was mixed on the ratio 0,15,30,45,60,75,90, and 100%. Then, in order to determine different kind of metabolizable energy CAME, AMEn, TME, TMEn) of waste, 30 grams of mixed feed were force-fed to 4 adult Leghom-type roosters, according to the method described by Sibbald. Statistical analysis showed that there were significant difference between AMEn of wastes. The amount of AMEn The amount of TMEn for biscuit, crisp, soup pasta, spagetti, rice pasta, chickpea precleaning and chickpea screening were, 4112, 3987, 3982, 3639, 3438, 2781, and 2573kcal/kg respectively. There were significant differenes (p0105) between amount of kind of metabolizable energy in different levels. The highest amount of AME was observed to be in 30% ratio of spaghetti waste to basal diet. There was significantdifferences (pOIO5) between amount of metabolizable energy of chickpea precleaning in two levels.
