A poisonous or toxic plant causes physiological or biochemical changes when eaten by livestock. These changes result in varying degrees of deviation from the normal state of health in animals. The effects of poisonous range plants vary from mild sickness to death, and can produce abortions, birth defects, photosensitization, chronic illness or debilitation. Although livestock deaths attributed to poisonous plants vary with years and location, recent estimates indicate the annual death loss is from 3 to 5% for cattle, sheep and horses.
