SUMMARY:

Plants that are toxic to farm animals continue to be an important topic of discussion, since in 2024, new plants of particular interest continued to be described, totaling approximately 167 species that cause imbalances in animals. Therefore, some of these plants have not yet been described in all farm animals. Therefore, the present study was developed with the objective of investigating poisoning by Urochloa decumbens and Senna obtusifolia in goats, addressing two distinct chapters that discuss these topics little explored in the scientific literature on the goat species. The first chapter presents an outbreak of poisoning by Urochloa decumbens (previously known as Brachiaria decumbens), a forage frequently used in Brazilian pastures, but which has been little investigated in relation to its toxic effects in goats. The chapter discusses the toxicity of this plant, the mechanisms involved in the poisoning, the clinical signs observed and the pathohistological aspects of the outbreak. The second chapter is dedicated to an article that discusses poisoning in goats caused by the plant Senna obtusifolia, a legume with toxic potential, but with few published studies on its effects on goats. The chapter describes the results of an outbreak in which goats were exposed to Senna obtusifolia and the clinical, pathological and histological effects of the poisoning observed. The chapter also analyzes environmental and management factors that may contribute to poisoning, in addition to discussing the impacts on production and health of goats. Both chapters aim to provide a deeper understanding of poisonings by poorly related plants in goats, offering valuable information for the prevention of outbreaks and for the implementation of safer management practices, with the aim of protecting animal health and reducing economic losses associated with poisonings by toxic plants in small ruminants. The study contributes to filling a gap in the scientific literature on the impact of these plants on goats and provides support for future research and more effective management actions.
