What is the primary management for vagal indigestion type 3?

• A. Aggressive IV fluid therapy (NaCl + KCl)
• B. Rumenotomy
• C. Rumen fistula
• D. Erythromycin

Answer: (A)

Vagal indigestion type 3 primarily disrupts gut motility and outflow, but the immediate need is to stabilize the patient. Aggressive IV fluid therapy rehydrates the animal, restores circulating volume, and corrects electrolyte losses (notably potassium and chloride) that accumulate with poor intake and rumen dysfunction. This stabilization is essential before attempting other treatments, because a rehydrated, perfused animal responds better to prokinetics or any surgical or decompressive measures that may follow. Decompressing the rumen or using prokinetics like erythromycin can be helpful later, but they don’t address the life-threatening dehydration and electrolyte imbalance right away.
