In managing chronic vagal indigestion, which statement correctly reflects its typical prognosis?

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

Answer: (D)

Chronic vagal indigestion is a persistent motility disorder of the forestomachs caused by vagus nerve dysfunction, leading to ongoing distension and reduced feed efficiency. Because the underlying motility problem tends to be chronic and only partially reversible with therapy, animals often fail to regain normal production or body condition despite intervention. This pattern makes the typical outlook guarded to poor, and in practice many cases end with euthanasia or culling due to persistent distension and consistently poor production. The other statements overstate how little impact the condition has or how reliably animals recover with treatment, which does not align with the common long-term course of this disease.
