Abstract：In order to solve manure pollution and heating problems in broiler farm, we prepared pellets made by broiler manure and sawdust, and combustion values were detected by a machine called oxygen bomb combustion calorimeter. Meanwhile, combustion values affected by different pro-portions of chicken manure and sawdust mixture as well as changes in storage time were also stud-ied. The mixture was divided into eight groups, in which 20%~100% chicken manure mixed. The re-sults show that the combustion value range was 11.12~15.48 MJ/kg in different groups, with the proportion of manure reduced combustion value increased significantly; the combustion values de-clined 4.90~0.69 MJ/kg when pellets stored a month later, and the combustion values were signifi-cantly reduced with the decrease in the proportion of broiler manure. Taken combustion value and storage time into consideration, it is recommended that the optima ratio of broiler manure and saw-dust is 4:6, which can fully meet the needs of each farm in the field.
