食道空腔突然是由大块的饲料（例如胡萝卜，地瓜根或未破裂和浸泡的蛋糕饲料）引起的。症状包括突然的食欲停止，头部和颈部拉直，唾液，咳嗽，持续的咀嚼和吞咽，摇头并引起恐慌。食道阻塞可以分为两种情况：食道和胸部的前部。可以在颈部的侧面感觉到食道的前部，而可以通过食管积聚的唾液的波动来诊断胸部阻塞。

治疗主要是及时排除食管障碍物，使其毫无障碍。 The methods include: taking out the obstruction from the mouth (pushing the obstruction into the mouth and then taking the object from the mouth with your hands), sending it (pushing it down into the stomach with an esophagus), pumping the air (inserting the gastric catheter into the esophagus and then pumping the air or inserting it while achieving the purpose of pushing the obstruction), forced movement (tethering the cow head and the forelimb ties共同迫使母牛移动20至30分钟，并利用宫颈肌肉运动来促进瘤胃的阻塞。

预防主要涉及标准化饲料处理。根饲料的加工可以通过达到一定程度的破碎化来消除疾病。
