treatment effect of pleurotus florida fungus on nutritive value of wheat stubble and date palm leaf.

wheat stubble (ws) and date palm leaf (dpl) were inoculated with pleurotus florida where in a completely randomized experiment, seven treatments including: 1)untreated ws (utws); 2) fungal treated ws at mycelial running stage (mtws); 3) fungal treated ws after first harvesting of mushroom (ftws1); 4) fungal treated ws after second harvesting of mushroom (ftws2); 5) untreated dpl (udpl); 6) fungal treated dpl at mycelial running stage (mtdpl); 7) fungal treated dpl after first harvesting of mushroom (ftdpl) were prepared. all treatments were sampled for chemical composition and in vivo trial when the voluntary intake and digestibility were determined in sheep. the cp was decreased(p<0.05)  in treatments of 3 and 4, and was increased (p<0.05) in treatments of 6 and 7, but the organic matter was decreased (p<0.05). ndf, adf and adl were increased (p<0.05) in treatments of  2 and 6 when compared with treatments of  1 and 5 respectively. the domi (g/kgmbw) was increased (p<0.05) in treatment of 2  in comparison with treatments of 1 and 4, and in treatment of 6 in comparison with treatments of 4 and 5. it is concluded that dmi, omi and digestibility of ws and dpl was increased(p<0.05) in mycellial stage in comparison with the untreated ws and dpl, but was reduced(p<0.05) after mushroom harvesting.
