Plantas hepatotóxicas: ocorrência de crotalaria retusa, cestrum laevigatum e tephrosia cinerea nas regiões de trairí potiguar e curimataú paraibano.

Abstract

Goats and sheep are raised on native or cultivated pastures, and in turn in extensive or semiextensive systems. This situation provides greater access for animals to plants considered to be toxic. Among the hundreds of toxic plants for production animals, we can highlight three hepatotoxic ones: Crotalaria retusa (rattlesnake rattle), Cestrum laevigatum (Dama-da-noite) and Tephrosia cinerea (Falso-indigo). Thus, the objective of this study was to evaluate the occurrence of these plants, which cause liver problems in goats and sheep in rural properties, located in municipalities in the semi-arid regions of Trairí potiguar and Curimataú in Paraíba. This work, developed through interviews with 65 producers in 20 cities located in the target regions, between the months of June to October 2020. Noting as a main result, that the three mentioned plants exist in the territories in question, and that only 1,5% of respondents knew its harmful effects. It is concluded that the local agriculture, faces considerable problems, in relation to the losses of animals that present clinical symptoms suggestive of liver intoxications, and that the scientific dissemination for the rural man is essential, in the sense of warning about the dangers hidden behind of the species of hepatotoxic plants that can occur in the region.
