Concerning the affected horse

  • Call your veterinarian as soon as you observe clinical signs compatible with the diagnosis of the disease (see “Diagnosis” )
  • Move your horse to a minimum because any movement aggravates the muscle destruction. However, if not already, you should know that your horse will soon lie down and be unable to get up. The ideal is to take him to the stable or the nearest shelter where he can receive appropriate care
  • Your horse is probably cold! Take its temperature and if you see it is suffering from hypothermia (rectal temperature <37 ° C), warm it; –
  • Plug it if the horse sweats;
  • Your horse is probably hungry! Be careful if you give it to eat, make sure it is able to swallow its food (give only small fractions of concentrates for horses)
  •  Give sugar and / or sugar water if the horse is able to swallow
  • Have a utensil to collect the urine in case the horse urinated in your presence. This is important because it will greatly help your veterinarian establish the diagnosis.

Concerning healthy horses grazing in a meadow where a case occurred

  • Put in stable all the horses found on the pasture (*)
  • Feed the horses with a complete mix
  • Outlaw grazing on the prairie for horses (at least in the fall and spring)
  • Provide the horses exclusively with water distribution
  • Closely monitor the horses for 72 hours (see clinical signs of the disease)
  • Ideally, ask your veterinarian to control horses (make a determination of activity of muscle enzymes in the blood).

(*) If no accommodation is possible, find another emergency dry grazing, away from any watercourse, with little or no tree and without the presence of dead wood. If you can move only some of your horse, choose those aged under 5 years and over 20 years.
