Because of it's low nutritive value and quality, it is nessesary to use chemical and biological processing to enrich it.In tIlls cxp,eriment rice straw was treated by fungi (plurotos-spp.), and nutritive value of the treated product was evaluated by using 18 afshari male lambs. Effects of 3 diets containing %25 of rice straw as dry matter basis: J ..non-treated lice straw,2fungal miceHium treated and 3-fungal treated rice straw after harvesting mushroom, were studied on the faUening traits of the Jambs, based on a completIly randomized desing. Lambs were fed by iso caloric & iso nitrogenous diets for 4 months (3 treatments with 6 replications). Daily dry matter intake of rations containing fllngall1licelJium treated and treated rice straw after mushroom harvesting were (1627.58, 1666.04 grs.) respectively and differed significantly with tlle non-treated rice straw (1509.00 grs.). There were not significant difference between the 3 treatment for: average daily gain (187 , 216 , 202 grs.) , final body weight (44.95,45,92,47.08 kgr.), Feed canversayion ratio (8.07 , 7.53 , 8.25) , meat yeild (5553.3 , 5873.3,5667.5 grs.), Bone (1793.33,1787.50, 1833.33 grs.), total weight of right carcass tree offat (8426.7 , 8931.7 ,8843.3 grs.), (P0.05).
