What you do today will determine whether pigs stay sick, get sick, recover, or die. Like a real pig barn, everything you do makes a difference! The purpose of this tool is educational, not intended to replace any other training. Your swine veterinarian is the contact person for any decision or question with your herd. Read on to find out your in-barn assignment in this simulation.";
