Do not wait until the animal cannot rise, by then it may be too late. Provide similar first aid to swine. Do not feed hay or bed animals on straw that contains bracken. A veterinarian can assist with treatment of affected animals, but this may be cost prohibitive. Evacuation of the rumen and intestinal tract is usually not of value, since the poison accumulates in the system for many days, and there may be little or no toxin remaining in the digestive tract to be removed once clinical signs appear.
Treatment is concerned with alleviating the clinical signs and providing supportive care.
Blood transfusions may be attempted, but the prognosis is poor for clinically affected animals. Bracken remains toxic when dry, and is never safe for consumption. Grazing animals should not be allowed access to bracken fern, especially if they have developed a taste for it. Provide supplemental feed if the pasture is low in adequate forage. Never use hay or bedding material that contains bracken.
