0.05). Fractional rate of GP (C) for WRM and fungi was lower in cow than buffalo (P<0.05). Regardless of microorganisms type, C was higher in buffalo was more than cow (P<0.05) and vice versa for B (P>0.05). Regardless of animal species, whole rumen microorganisms had higher digestibility and potential of GP than fungi (P>0.05), but there was not any difference for rat of GP between them. In SRFC, DM digestibility of STP by fungi at day 12 in buffalo was significantly more than cow (P<0.05). The concentration of fungi per ml of rumen liquer in cow was more than buffalo (P<0.05). Although, the rumen population fungi in cow was more than buffalo, but that digestibility of fungi (in specific rumen fungi culture) and WRM of buffalo was more than cow in present experiment. Therefore, the results of this study showed the advantage and supremacy of buffalo in usage the low quality roughages. ]]>

0.05) by the experimental diets. Digestibility of DM and NDF decreased linearly (P<0.05) while no differences (P>0.05) were detected in OM and CP digestibility by inclusion of PBL in the diets. The Ruminal acetate concentration decreased but ammonia increased linearly (P<0.05) as the rate of PBL enhanced in the diet, however no differences (P>0.05) were obtained for the other metabolites between the animals received different diets. Blood urea-nitrogen increased linearly (P<0.05) by increasing of PBL in the diet, but other blood metabolites were not influenced (P>0.05) by the experimental rations. Results of current study indicated that feeding PBL in the diet of Moghani lambs up to 21percent, did not affect the nutrients intake and growth performance but decreased digestibility of DM and NDF and ruminal acetate concentration. In Addition, feed cost per unit of live weight gain was decreased (P<0.05) by inclusion of PBL in the ration. It is concluded that processed broiler litter could be used up to 21 percent of the diet for fattening lambs.]]>
