Disposal of Swine Mortalities

Publish Date: 10/15/2020

There is no best way to dispose of swine mortality carcasses. While some methods may work well for managing routine mortalities, the ability to scale them up to handle large numbers can be difficult. These methods may not adapt to times when catastrophic mortalities occur. The optimum system for any particular farm location is based on a number of criteria, including the current state of the protein/oil market, the biosecurity required, the distance to processing sites, the local public's perception, the government regulations that apply to that location, the environmental conditions, and the ability of the farm to carry out the different procedures. The death losses at a farm can be classified broadly as one of two types, routine or catastrophic. Routine mortalities represent a small proportion of herd and occur throughout the course of normal production. Catastrophic mortality events involve high death losses within a distinct period of time. These methods can also be used for catastrophic loses but the larger scale in a shorter time frame often increases process intensity. Additionally if losses are due to disease, they have a higher biosecurity risk.
