Today is no joke. Take care of the animals, take care of yourself.

🔥 Wildfire Smoke & Horse Health 🐴💨

Poor air quality can be harmful not only to us but our horses too. Smoke from wildfires can irritate a horse's respiratory system and cause fatigue, coughing, difficulty breathing, etc.

You can monitor local air quality at www.airnow.gov. During periods of poor air quality, you can protect your horse's health by:

🐎 Limiting or avoiding exercise.
💧 Providing free access to fresh water.
💦 Controlling dust such as watering dry lots and soaking or feeding dust-free hay.
🕰 Allowing time for recovery: airway damage from wildfire smoke takes 4 to 6 weeks to heal after air quality returns to normal.
☎️ Consult your vet if you notice signs of smoke irritation.

If you feel hot, your horse feels even hotter.

Horses have a much harder time processing heat and humidity than humans. And among horses, foals usually cannot handle as much heat as adult horses. A mare may be fine, but her foal may be getting sick from being out on a hot day.

Horses with heavy muscling or excess fat or in poor condition will also be more susceptible to heat exhaustion. Keep in mind that exercise is a major source of body heat and strenuous work on a hot, humid day can lead to problems in a short period of time for even the best-conditioned horse.

Does this mean you should not ride on a hot and humid day? Not necessarily. It just means you should take precautions and use common sense. And remember: don't push it! If your horse looks tired, it’s time for a drink, a cold bath, and a break in the shade.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has provided an important update on New World Screwworm which has been detected in a bovine in Zavala County, Texas. Read the full press release here: https://www.aphis.usda.gov/news/agency-announcements/usda-confirms-presence-new-world-screwworm-united-states

General information about New World Screwworm (NWS) can be found in the text below and in the attached infographic.

The adult screwworm fly is about the size of a common housefly (or slightly larger), with orange eyes, a metallic blue or green body, and three dark stripes along its back. It gets its name from the behavior of its larvae (maggots) as they burrow (screw) into the wound, feeding as they go. The maggots (larvae) cause extensive damage by tearing at the hosts’ tissue with sharp mouth hooks. The wound can quickly become enlarged and deeper as more maggots hatch and feed on living tissue.

Because they feed on live flesh, NWS maggots may burrow deep into wounds or openings, while other species of maggots may appear around the outer surface of the wound. In addition, even the smallest wounds have the potential to attract flies, so it is imperative that you keep a close eye on your animals for any signs of wounds.

Lastly, NWS infestations are a reportable disease! Immediately report any suspicious wounds, maggots, or infestations to a local accredited veterinarian, your State Animal Health Official, or a USDA veterinarian.
