What is biosecurity? Biosecurity can be subdivided into 3 parts: 1) bio-exclusion involves keeping pathogens out of a herd, 2) bio-management involves managing pathogens already in a herd to minimize the negative consequences, and 3) bio-containment involves preventing pathogens from escaping a herd and putting other farms at risk. Bio-exclusion will be the focus of this factsheet. Improving bio-exclusion requires taking time to identify the most significant vulnerabilities on farms to determine what should be done next. It starts with identifying vulnerabilities that can result in pathogens being introduced into a herd (step 1) and then prioritizing bio-exclusion control measures to address them (step 2). Historically, relatively little time has been spent on the first step resulting in slow progress in improving biosecurity.

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.
