As a consequence of normal swine production, mortalities must be handled on a daily basis. Average death losses of 4100 kg/year (9,000 lbs/year) per 100 sows pose a significant management and disposal task for Iowa swine producers. Several methods of disposal have been used for this costly and time-consuming task.
