Which of the following best describes the prognosis for chronic vagal indigestion?

• A. Excellent prognosis with early intervention and dietary management.
• B. Prognosis varies; most cases recover fully with conservative therapy.
• C. There is no impact on long-term productivity; production remains normal.
• D. Generally guarded to poor; many cases are euthanized or culled due to persistent distension and poor production.

Answer: (D)

Chronic vagal indigestion reflects lasting loss of normal rumen motility due to vagus nerve dysfunction, causing persistent ruminal distension, reduced eructation, and ongoing feed inefficiency. Because the nerve damage is usually not reversible, the abnormal motility tends to persist, so animals struggle to maintain body condition and production over time. Interventions may offer only temporary relief in some cases, but they rarely restore normal function or production in the long term. That makes the prognosis generally guarded to poor, with many affected animals eventually euthanized or culled due to ongoing distension and poor production. The idea that outcomes are generally excellent, fully recover with conservative therapy, or have no impact on production doesn’t fit the typically chronic, progressive nature of this condition.
