Modelling the links between farm characteristics, respiratory health and pig production traits

Abstract Sustainable livestock production requires links between farm characteristics, animal performance and animal health to be recognised and understood. In the pig industry, respiratory disease is prevalent, and has negative health, welfare and economic consequences. We used national-level carca...
