Seneciosis in cattle associated with ingestion of Senecio brasiliensis under different forms of consumption in Santa Catarina state, Brazil

Abstract

ABSTRACT: This study identified the different forms of ingestion of Senecio brasiliensis in cattle, diagnosed by the Animal Pathology Laboratory at CAV-UDESC, in the state of Santa Catarina, Brazil. A retrospective evaluation from 1987 to 2016 showed that ingestion has occurred voluntarily due to the presence of the adult plant in native field and/or involuntary, due to the presence of the plant in hay and silage, provided in the trough together with other pastures or by contamination in grain residues. These different forms of ingestion demonstrate the importance of epidemiologic investigation in the diagnosis of seneciosis.
