Effective farm biosecurity prevents disease introduction that causes suffering, making it a primary welfare investment alongside its economic role.
Disease prevention through biosecurity is one of the most durable welfare investments available in livestock farming. Disease outbreaks cause mass suffering and in many cases mass culling. Basic biosecurity measures prevent most introductions at modest cost. Framing biosecurity as a welfare investment alongside its economic role increases farmer motivation for consistent implementation of measures that may seem inconvenient in the short term.
