Composting Dead Swine by Using Agricultural Residues

  • 발행 : 1998.10.01

초록

Dead animals amended with agricultural rersidues are utilized ai a compost to promote soil fertility and reduce environmental pollution by traditional methods of livestock mortalities. The full-scale bin composting swine mortality in roofed system with three amendments was very successful in reaching sufficient temperature above 55$^{\circ}C$ long enough for pathogen kill. The average temperature of tile compost material in dead swine amended with corn stover increased rapidly to 64$^{\circ}C$ on the 2nd day after primary composting and dropped to near ambient temperature on the 140th day of composting. The composting temperature of corn stover and wheat straw is more efficient for swine carcass composting than that of sawdust.
