This study included 94 cows aged 2.1 to 12.0 years (5.2 ± 2.05 years) that were examined at a referral clinic because of type-1 abomasal ulcer. The most common clinical findings were poor general health status (94%), partial or complete anorexia (93%), congested scleral vessels (89%), decreased skin surface temperature (76%), decreased or absent faecal output (72%), abdominal guarding (59%), tachypnoea (56%), rumen atony (53%) and positive percussion and simultaneous auscultation and/or ballottement and simultaneous auscultation on the right side (53%). The most common laboratory findings were hypokalaemia (68%), positive base excess (60%) and azotaemia (51%). The chloride concentration of rumen fluid was increased in 48% of the cows. The diagnosis of type-1 ulcer was made during laparotomy and/or postmortem examination. One or more concurrent diseases were diagnosed in 97% of the cows. Seventy-eight (83%) cows were euthanased immediately after the initial examination, during laparotomy or after unsuccessful treatment, and eight (8.5%) cows died, and all were examined postmortem. Eight (8.5%) cows were discharged and six of these made a complete recovery.
本研究纳入了 94 头年龄为 2.1 至 12.0 岁（5.2 ± 2.05 岁）的奶牛，这些奶牛因 1 型真胃溃疡在转诊诊所接受检查。最常见的临床发现是一般健康状况不佳（94%）、部分或完全食欲不振（93%）、巩膜血管充血（89%）、皮肤表面温度降低（76%）、粪便排出量减少或消失（72%）、腹部紧张（59%）、呼吸急促（56%）、瘤胃弛缓（53%）以及右侧叩诊和/或听诊同时出现鼓音和波动感（53%）。最常见的实验室发现是低钾血症（68%）、碱剩余阳性（60%）和氮血症（51%）。48%的奶牛瘤胃液中氯离子浓度升高。1 型溃疡的诊断是在剖腹术和/或剖检时做出的。97%的奶牛被诊断出患有一种或多种并存疾病。78 头（83%）奶牛在初次检查、剖腹术或治疗失败后立即被实施安乐死，8 头（8.5%）奶牛死亡，均进行了剖检。8 头（8.5%）奶牛出院，其中 6 头完全康复。
