What are the two types of abnormal motor function that cause forestomach disease?

• A. Acute ruminal tympany; Vagal indigestion
• B. Rumen acidosis; Simple indigestion
• C. Abomasal ulcers; Traumatic reticuloperitonitis
• D. Bloat; Ruminal atony

Answer: (A)

Disturbances in forestomach motility show up mainly as two functional patterns: gas distension from unable-to-eructate conditions (bloat) and a neurogenic motor disorder affecting the rumen–reticulum (vagal indigestion). In bloat, gas builds up in the rumen because eructation is blocked or ineffective, so the rumen becomes distended and animal well-being quickly deteriorates. In vagal indigestion, disruption of the vagus nerve alters coordinated contractions and the normal flow of ingesta, leading to chronic distension and impaired movement of the forestomachs. Other listed conditions are metabolic issues or inflammatory/structural diseases of other parts of the stomach or abdomen, not these two primary motor-function categories. So the combination of acute ruminal tympany (bloat) and vagal indigestion best represents the two abnormal motor function types affecting the forestomachs.
