摘要

Livestock poisoning by plants is a frequent occurrence which determines severe losses, such as the fall in the milk and meat production, the cost of expensive treatments, the state of immunosuppression, or even the animal's death. Cattle ingest toxic plants only when there is food shortage, when they cannot select what they eat, or when they ingest food for preference, which is the case of Hovenia dulcis fruits, very rich in sucrose. This plant is widely distributed in the southern and southeastern Brazilian regions. In literature, there are some cases of severe human liver injury associated with a long-term of IL dulcis leaf and fruit tea intake, and only one report regarding spontaneous poisoning of goats caused by this plant ingestion. However, its toxic effects associated with spontaneous ingestion by cattle have never been reported. This paper reports the first case of spontaneous poisoning in cattle by H. dulcis, which occurred in a dairy farm in southwest Parana, Brazil. Three cattle individuals showed anorexia, ruminal atony, severe diarrhea and neurological tournament, head pressing, blindness. ataxia, and circling. The necropsy of the animals was done, and the remaining alterations were restricted to the digestive system and brain. The clinical signs presented by the animals are characteristic of polioencephalomalacia (PEM), caused by changes in the thiamine metabolism. Furthermore, clinical signs, gross, and microscopic lesions as well as the large amount of the plant throughout the digestive segment led to a diagnosis.

Dulcis在牛牛的第一种伴随中毒的案例。巴西西南西南部的奶牛场发生。三个牛个体显示厌食症，瘤胃，严重的腹泻和神经学锦标赛，头部压迫，失明。共济失调和盘旋。动物的尸检是完成的，并且剩余的改变仅限于消化系统和脑。由动物呈现的临床迹象是由硫胺新陈代谢的变化引起的Poliocencalomalacia（PEM）的特征。此外，临床症状，总粗糙和微观病变以及整个消化系统的大量植物导致诊断。
