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.
