Bracken Fern (Pteridium aquilinum) is a common and widespread fern species that grows throughout the United Kingdom. While it is a valuable source of food and shelter for wildlife, it can also be toxic to horses if ingested in large quantities. In this blog, we will discuss the effects of bracken fern toxicity in horses and what you can do to prevent it.

Bracken fern contains compounds known as pterosins that can be toxic to horses. When horses consume bracken fern, they may experience a variety of symptoms including gastrointestinal upset, weight loss, anemia, and even death in severe cases. The toxic effects of bracken fern are cumulative, so even small amounts consumed over a long period of time can lead to serious health problems.

One of the biggest concerns with bracken fern toxicity in horses is that the symptoms can be difficult to detect in the early stages. Horses may show mild signs of gastrointestinal upset, such as colic or diarrhea, but these symptoms can also be caused by other factors. As the toxicity builds up, horses may begin to show more severe symptoms, such as weight loss, anemia, and even death.

To prevent bracken fern toxicity in horses, it is important to provide them with access to alternative food sources, such as hay or pasture grass, and to keep them away from areas where bracken fern is growing. If you suspect that your horse may have ingested bracken fern, it is important to seek veterinary attention as soon as possible. Your vet may recommend testing for bracken fern toxicity, as well as other tests to rule out other causes of the symptoms.

In conclusion, bracken fern is a common and widespread fern species in the United Kingdom that can be toxic to horses if ingested in large quantities. To prevent bracken fern toxicity in your horse, it is important to provide them with alternative food sources and to keep them away from areas where bracken fern is growing.
