some steps to reduce the risk of introducing infectious diseases
Some steps to reduce the risk of introducing infectious diseases:
  • Limit people\'s access to brood mare and foaling barn(s).
  • Separate breeding horses from others
  • Limit people\'s access to barns housing horses returning from major shows or events
