First Frost Reminders
The first autumn frost brings some short-term health hazards that need watching.
The first frost of autumn marks the arrival of some short-term seasonal health hazards that bear watching.
- Some deciduous leaves can be deadly in fall, particularly those of red maple and wild cherry trees. Identify all such seasonally toxic trees on your property, and keep horses from their fallen leaves for at least 30 days. Also, during this time of fall fix-ups, be alert for yard wastes that might be dumped within reach of your horses. Besides toxic leaves, they may include highly hazardous landscape trimmings, such as yew and oleander.
- Frosty nights make for dew-soaked morning pastures that can contribute to scratches on horses' pasterns and "dew poisoning," the painful puckering and cracking of the skin on the muzzle. Treat both conditions by gently but thoroughly cleaning the affected skin and, after drying, coating it with an anti-chapping agent, such as Desitin ointment.
- Many larger flies are killed off by the first frost, but smaller pests, such as gnats and horn flies, seem to go into a final frenzy of activity as cold approaches. Head shaking, eye and ear irritation, and crustiness along the belly midline are all signs of this last attack. Keep fly masks, ear covers and insectide protection going for a few more weeks.
- The return of cooler, wetter weather can produce a flush of lush pasture growth that could potentially trigger laminitiso via an equine digestive tract long accustomed to parched forage. Keep at-risk horses off of regreening pastures or supply free-choice hay so they can take in gut-stabilizing roughage along with the succulent growth.
