To assess signalment, history, results of clinical and laboratory testing, and outcome for beef cattle with a left displaced abomasum (LDA), right displaced abomasum (RDA), or abomasal volvulus (AV).
Retrospective study.
19 beef cattle with an AV, LDA, or RDA.
Signalment; history; results of physical examination, diagnostic testing, and surgical exploration; and condition of the animal at discharge were obtained from medical records.
Fourteen cattle had an AV, 4 had an RDA, and 1 had an LDA. Duration of clinical signs ranged from 1 to 21 days. Eighteen cattle had an AV or RDA; 7 were Brahmans, 12 were males, and median age was 10 months. Abdominal distention was observed in 11 cattle, heart rate of > or = 100 beats/minute was detected in 14, and the abomasum was palpable per rectum in all cattle in which per rectal examination was performed. Leukocytosis, neutrophilia, hyperglycemia, azotemia, hypochloremia, and hypokalemia were common laboratory findings. At surgery, 3 cattle with an AV or RDA had a ruptured abomasum. Of the remaining 15 cattle, 12 survived.
Clinical course in beef cattle with an AV or RDA was more protracted than that typically associated with these conditions in dairy cattle, but survival rate in beef cattle that did not have rupture of the abomasum was similar to that of dairy cattle.
Abomasal displacement should be considered for beef cattle with abdominal distention. Prognostic indicators recommended for use in dairy cattle may not be useful for beef cattle.
评估患有左方变位皱胃（LDA）、右方变位皱胃（RDA）或皱胃扭转（AV）的肉牛的特征、病史、临床及实验室检查结果和预后情况。
回顾性研究。
19头患有AV、LDA或RDA的肉牛。
从病历中获取动物特征、病史、体格检查结果、诊断性检查结果、手术探查结果以及出院时的状况。
14头牛患有AV，4头牛患有RDA，1头牛患有LDA。临床症状持续时间为1至21天。18头牛患有AV或RDA；其中7头为婆罗门牛，12头为公牛，中位年龄为10个月。11头牛出现腹部膨胀，14头牛检测到心率≥100次/分钟，在所有进行直肠检查的牛中均可经直肠摸到皱胃。白细胞增多、中性粒细胞增多、高血糖、氮血症、低氯血症和低钾血症是常见的实验室检查结果。手术时，3头患有AV或RDA的牛皱胃破裂。其余15头牛中，12头存活。
患有AV或RDA的肉牛的临床病程比通常与奶牛这些病症相关的病程更迁延，但皱胃未破裂的肉牛的存活率与奶牛相似。
对于出现腹部膨胀的肉牛应考虑皱胃变位。推荐用于奶牛的预后指标可能对肉牛无用。
