What is the overall prognosis for chronic vagal indigestion?

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

Answer: (A)

Chronic vagal indigestion reflects a lasting loss or severe impairment of rumen motility due to vagus nerve damage, so gas and ingested feed aren’t moved or expelled properly. This leads to persistent ruminal distension, poor appetite, weight loss, and markedly reduced production. Because the underlying motility problem is not reliably reversible and secondary complications can develop, the long-term outlook is typically guarded to poor. In practice, many chronically affected animals are euthanized or culled because they cannot maintain production or recover, making an excellent or fully recoverable prognosis unlikely. Early intervention might help in some acute or reversible cases, but for the chronic form the overall prognosis remains poor, which is why the described answer is the best fit.
