Abstract: Massive amount of rumen content and blood were produced from the slaughtered animal in a single day of Eid-ul-Azha in Bangladesh that creates an unhygienic and hazardous environment at that time. A convenient composting method can efficiently utilized these rumen contents and blood. For this purpose, three different treatments mentioned as rumen content only (T1), rumen content with biogas slurry (T2) and rumen content with cattle blood (T3) were studied with 3 replications for anaerobic composting. The parameters studied were Organic Matter (OM), Crude Protein (CP), Carbon Nitrogen ratio (C/N ratio), Crude Fiber (CF), Ether Extract (EE), Nitrogen Free Extract (NFE), ash and pH. The result revealed that amount of CP was higher in T3 (17.43%) followed by T2 (16.27%) after 90 days of anaerobic composting and the differences were significant (p<0.01) among treatment groups. Initial and final C/N ratios were 33.46 and 31.42, 27.66 and 23.88 and 27.93 and 22.83 in case of T1, T2 and T3, respectively. Final C/N ratio showed the significant difference (p<0.01) among different treatment groups. The pH of the final compost was significantly increased in T3 (22%) followed by T2 (20%).
