Abomasal dilatation and emptying defect was identified in 14 of 130 Suffolk sheep from a single flock in northern California. Abomasal dilatation and emptying defect was diagnosed in 13 of the sheep between November 1986 and April 1987. All affected sheep were ewes and in all, the condition developed during the lambing season. Clinical signs consisted of chronic anorexia and weight loss. Laboratory data from affected ewes reflected concurrent disease and was not helpful in diagnosis of the disease. Necropsy of 13 affected ewes revealed a distended, ingesta-filled abomasum in all of them. The brain stem of 6 ewes was examined, and lesions suggestive of scrapie were not observed. Pedigree analysis determined that in this flock, abomasal dilatation and emptying defect development was independent of sire. A relationship between the age of affected ewes and the disease was not found. Treatment was unsuccessful in 13 ewes, but 1 recovered after treatment with metoclopramide.
在加利福尼亚北部一个单独羊群的130只萨福克羊中，有14只被发现存在皱胃扩张和排空障碍。1986年11月至1987年4月期间，在13只羊身上诊断出皱胃扩张和排空障碍。所有患病羊均为母羊，且这种情况均在产羔季节出现。临床症状包括慢性厌食和体重减轻。患病母羊的实验室数据反映出同时存在其他疾病，对该病的诊断没有帮助。对13只患病母羊进行尸检发现，它们的皱胃均扩张且充满食糜。检查了6只母羊的脑干，未观察到提示羊瘙痒病的病变。系谱分析确定，在这个羊群中，皱胃扩张和排空障碍的发生与父系无关。未发现患病母羊的年龄与该病之间存在关联。13只母羊的治疗未成功，但1只在用胃复安治疗后康复。
