Com o objetivo de verificar quais são as plantas incriminadas como tóxicas para ruminantes do Sudoeste de Goiás, foram realizadas 108 entrevistas com produtores rurais, médicos veterinários, zootecnistas e agrônomos de 18 municípios da região. Foram apontadas como tóxicas para ruminantes: Brachiaria spp., Enterolobium contortisiliquum, Dimorphandra mollis, Palicourea marcgravii, Pteridium aquilinum e Sorghum vulgare. Adicionalmente, foram informadas intoxicações menos frequentes por Senna occidentalis, Stryphnodendrum obovatum e Manihot esculenta. Casos isolados de intoxicação em bovinos por Asclepias curassavica e Pterodon emarginatus foram descritos por alguns entrevistados. Este trabalho demonstra que intoxicações por plantas tóxicas são frequentes na região avaliada e representam importante causa de prejuízos econômicos aos pecuaristas locais.
The aim of this study was to investigate the toxic plants for ruminants in the Southwestern region of Goiás State, Brazil. 108 people (farmers, veterinarians, zootecnists and agronomists) from 18 counties were interviewed. The following plants were described as toxic for ruminants: Brachiaria spp., Enterolobium contortisiliquum, Dimorphandra mollis, Palicourea marcgravii, Pteridium aquilinum and Sorghum vulgare. In addition, less frequent poisonings by Senna occidentalis, Stryphnodendrum obovatum e Manihot esculenta were reported. Isolated cases of poisoning by Asclepias curassavica and Pterodon emarginatus were described by some interviewers. Based in the results of this research, it is concluded that poisoning by toxic plants are frequent in the studied region and represent important cause of economic losses to the local farmers.
