Plantas tóxicas para animais produção da região Sudoeste da Bahia. Uma Revisão

Abstract

A survey on toxic plants for livestock was performed in the Southwest region of the state of Bahia, Brazil. One hundred twenty people were interviewed, including farmers, veterinarians, and agrarian technicians from 30 municipalities. In total 80 outbreaks of intoxication by toxic plants were recorded. The affected animal species were the bovine, caprine, ovine and equine. The main species of toxic plants, in decreasing order of outbreaks were Pteridium arachnoideum, Amorimia rigida, Ricinus communis and Froelichia humboldtiana. Other plants pointed as causing intoxication were Brachiaria spp., Marsdenia spp., Manihot spp., Mimosa tenuiflora, Thiloa glaucocarpa, Enterolobium contortisiliquum, skin of Coffea arabica and Asclepias curassavica. The species Imperata brasiliensis Trin., Senna acurensis, Capparis jacobinae and Cecropia hololeuca Miq. need to have confirmed toxicity. New studies testing the toxicity of the mentioned plants must be performed, in order to widen the information about poisoning by plants. Based in the results, it is concluded that poisoning by toxic plants are frequent in livestock in the Southwest region of the state of Bahia and represent an important cause of economic losses to farmers.
