The present report describes two novel cases of suspected intoxication with Galega officinalis in 6- and 21-year-old Arabian mares displaying acute respiratory signs. Both animals showed signs of pulmonary edema at physical examination, with the oldest of the two also manifesting severe dyspnea and foamy nasal discharge. The mares were grazing on the same meadow with hay available ad libitum. Botanical analysis of the latter showed traces of the toxic plant Galega officinalis (L.), which has been daily ingested at a dose of around 14 g of dry matter for three days. Based on the respiratory signs and the presence of goat's rue in the mares' feed, a presumptive diagnosis of plant poisoning was assumed. Dietary change and treatment allowed the 6-year-old mare to fully recover in 3 days while a longer period of about 2 weeks was necessary for the older horse. Horses avoid eating fresh goat's rue as its palatability is low, yet poisoning may still happen in these species when the plant is found in dried and processed feed material.
本报告描述了两例疑似 6 岁和 21 岁阿拉伯母马因食用 Galega officinalis 而中毒的新病例，这些母马表现出急性呼吸道症状。两只动物在体检时都表现出肺水肿的迹象，其中年龄较大的一只还表现出严重的呼吸困难和泡沫状鼻漏。这些母马在同一片草地上放牧，有自由采食的干草。对后者的植物学分析显示出有毒植物 Galega officinalis (L.) 的痕迹，这些植物已经被每天摄入约 14 克干物质，连续摄入了三天。根据呼吸症状和母马饲料中存在的山羊豆，假定为植物中毒。饮食改变和治疗使 6 岁的母马在 3 天内完全康复，而年龄较大的马则需要大约 2 周的时间。马不喜欢吃新鲜的山羊豆，因为它的适口性很差，但当这种植物在干燥和加工的饲料中被发现时，这些物种仍可能中毒。
