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%).
