H.  aPoisonous plants affecting livestock in Brazil.  c2002  aPlant poisoning, together with rabies and botulism, are the main causes of death in adult cattle in Brazil. Estimates indicate that about one million head of cattle die annually through plant poisoning in this country. There are approximately 75 plants of practical importance to animal husbandry that have had their toxicity confirmed by experiments with the animal species affected under natural conditions. The great majority of these plants only occur in Brazil and neighboring countries. A few of them are forage plants that can become toxic under cenain conditions. In this review the poisonous plants of interest to animal husbandry of Brazil are divided according to the clinical-pathological picture they cause in cattle; only cyanogenic plants, 'Plants that cause nitrate/nitrite poisoning and the ones that cause oxalate poisoning, are grouped according to their toxic principles. Plants and their toxic principles, or of which possible toxic compounds have been isolated, are listed.  aplant poisoning  aPlanta Tóxica1 aDÖBEREINER, Jürgen.1 aPEIXOTO, P.
