狭叶车前（Plantago lanceolata L.）研究了其作为绵羊利尿剂的潜力。七天，两组羊（n = 8）提供了黑麦草或大蕉饮食，具有相似的水含量。每天测量饲料中的干物质、新鲜粪便重量和粪便含水量，以及尿液的体积、比重和渗透压。试验第1天的尿量与试验第2-6天的尿量有显著性差异（P < 0.05），因此单独分析结果。在第1天，车前草羊的尿量比黑麦草羊高（1.7 L，P < 0.05），并且在研究期间的剩余时间内，车前草羊每天的尿量比黑麦草羊多约0.5 L。由于两种日粮的饲料摄入量和饲料水分含量基本相等，因此本研究提供了第一个直接证据，表明绵羊摄入车前草时可能通过减少肾脏对水的重吸收而引起利尿。
Narrow-leaved plantain (Plantago lanceolata L.) was investigated for its potential to act as a diuretic in sheep. For seven days, two groups of sheep (n = 8) were provided with either ryegrass or plantain diets that had similar water content. Dry matter in feed, fresh faecal weight, and faecal water content was measured daily, as well as volume, specifi c gravity and osmolality of urine. Urine volumes on Day 1 of the trial were signifi cantly different to those of Days 2-6 of the trial (P < 0.05) so the results were analysed separately. Plantain sheep had a higher volume of urine (by 1.7 L, P < 0.05) on Day 1 than Ryegrass sheep and continued to produce about 0.5 L more urine each day than Ryegrass sheep for the remainder of the study period. Because intakes of feed and feed water content for the two diets were essentially equal, this study provides the fi rst direct evidence to show that plantain causes a diuresis when it is ingested by sheep, possibly by reducing reabsorption of water in the kidneys.
