How can I avoid livestock losses to poisonous plants?

Preventing animals from consuming too much of a poisonous plant in the first place is the best way to avoid livestock losses to poisonous plants. However, livestock grazing on rangelands generally cover large areas with a diverse array of plants. It is difficult, if not impossible, to prevent livestock from coming into contact with poisonous plants. However, a few guidelines can minimize the likelihood of a severe loss to poisonous plants. To protect your animals from poisoning: • Learn to identify the poisonous plants that grow on your rangeland. • Learn the conditions under which these plants can be dangerous to your livestock. • Develop a grazing plan to improve your rangeland and prevent poisoning of your livestock by plants. Graze your rangelands at the proper time, and do not overgraze them. • Do not allow animals that have been under stress or that are overly hungry to graze in areas infested with poisonous plants. • Provide adequate water for your livestock. • Be especially careful when grazing newly introduced livestock on your rangeland. • Provide adequate salt and other supplements as needed. • Control poisonous plants where feasible. If your animals get sick, consult your veterinarian to ensure proper diagnosis and treatment. If a poisonous plant is involved, identification of the plant is essential for any corrective action.
