A new study confirms antibiotic-free production strategies leave pigs at considerable risk of exposure to disease and responsible use of antibiotics can significantly improve animal health. Prior to this study, no data has been available regarding the production performance and health of animals raised antibiotic-free when under a disease challenge such as PRRSV, the most significant pathogen in the global swine industry.

“No one has ever done an experiment of this size under representative conditions comparing antibiotic-free production to production strategies utilizing judicious use of antibiotics,” says Scott Dee, DVM, lead researcher of the study and director of research with Pipestone Applied Research.
