The study was conducted from November 2015 to May 2016 in and around Dale Sadi woreda, Kellem Wollega Zone of Oromia regional state, Western Ethiopia to assess and identify the potential toxic plants to livestock. Structured questionnaires in two forms were applied and 142 individuals: 124 livestock owners and traditional healers, and 18 animal health practitioners were interviewed. The result of this assessment indicated that more than 135 (95%) respondents have disclosed the presence of plant poisoning to livestock in the study area. In this study, 35 toxic plant species were identified and documented. The major problems that expose the livestock to toxic plants as explained by study participants were a shortage of feed (54.8%) and nutritional deficiency that causes abnormal feeding habits (25.9%). The animals are usually poisoned at the end of the rainy season and during the dry season. The most common plant parts that cause toxicosis to the livestock were the whole (all parts of the plant) and leaf. Among the toxic plants: Parthenium hysterophorus (18.51%), Marga Cita (NA) (15.55%), Medica goburu wed (14.81%), Sorghum bicolor (8.2%), and Euphorbia spp. (4.44%) were the most frequently complained toxic plants in the study areas. The majority of the plants that cause toxicosis to the animal were by ingestion with a single exposure (single consumption) or and among species, bovines were found to be susceptible animals. Generally, the study indicates the existence of many toxic plants in the area that needs public awareness to reduce livestock exposure and further research should be carried out to determine the toxicogenic ingredients of the plants.
