Animal agriculture is looking for innovative means to dispose of mortalities. Composting is an environmentally friendly option that retains the nutrients of the animal and organic materials. Southern U.S. swine farrowing operations often use sawdust as a C source for mortality composting. The objective of this study was to compare the farm standard mortality composting procedure (using sawdust and water) with other mixtures having supplementary C and N provided by broiler litter and by replacing water with swine lagoon effluent.
