Mortality reduces gross income but also changes the cost of pig production. Accurately projecting the impact of mortality on net income is important to determine if the marginal income of lower mortality is greater than the marginal cost of improving mortality. This fact sheet focuses on the potential economic benefit of improving mortality which builds on previous work (Crooks et al., 1993; Holtkamp, 2008; Dhuyvetter, 2014). This calculation is not a trivial task because the economic value of lowering mortalities depends on various prices and production efficiencies.

Sound animal health and housing practices help to minimize mortality. However, there will always be a need to dispose of mortality. Rendering, composting, incineration, sanitary landfills, burial, and disposal pits are commonly available as options . Composting is an attractive option because it is an environmentally friendly disposal method that captures the nutrient value of the mortality and organic amendments. Since composting usually takes place on the farm as the mortality occurs, the bio-security concerns associated with storing and transporting carcasses are greatly reduced. When properly managed, composting will generate few, if any, objectionable odors. However, as with any management practice, an understanding of the underlying principles, proper design, and proper management are required for successful results.
