What is the prognosis for horses with johnsongrass poisoning?

As summer approaches and pasture grasses begin to grow rapidly, horse owners must be vigilant in monitoring their animals for signs of poisoning. Johnsongrass ( Sorghum halepense ), a robust and invasive plant species, is particularly troublesome as it contains high levels of prussic acid.

Symptoms of johnsongrass poisoning typically appear within minutes to hours after ingestion and may include anxiety, Ataxia, labored breathing, increased heart rate, increased body temperature, and dark red or brown mucous membranes. In severe cases, horses may go into shock and collapse. If left untreated, johnsongrass poisoning can be fatal.
If you suspect your horse has ingested johnsongrass, it is important to seek veterinary care immediately. There is no specific antidote for prussic acid poisoning, so treatment will be focused on supportive care. This may include IV fluids to prevent dehydration, oxygen therapy to help with breathing, and close monitoring of heart function. In some cases, horses may also need to be placed on ventilators.
With proper medical treatment, the vast majority of horses will make a full recovery from johnsongrass poisoning. However, some may experience long-term kidney damage or laminitis as a result of the toxicity. It is important to work with your veterinarian to create a care plan that will help minimize the risk of these complications and give your horse the best chance for a full and speedy recovery.
