  1. 1The number of animals within each variable may differ based on completeness of obtained on-farm data
  2. 2Compliance was based on the residing veterinary recommendation, farm standard operation protocol and label compliance for each swine illness
  3. 3Overall compliance was defined as perfect compliance on drug, dose and frequency (all correct)
  4. 4This category includes infrequently reported health conditions (bleeding lesion, bacterial infection, off feed, diarrhea, non-specific inflammation, shoulder sores)
  5. *No sow was scored a zero on the Zinpro lameness scale
