Which condition is a disease of the abomasum?

• A. Ruminal tympany
• B. Vagal indigestion
• C. Abomasal ulcers
• D. Simple dietary indigestion

Answer: (C)

Abomasal ulcers are a lesion localized to the abomasum, which is the glandular, true stomach of ruminants where acid secretion occurs. This makes them a disease of the abomasum specifically. The other options involve different parts or types of digestive problems: ruminal tympany is gas distension of the rumen (a forestomach), vagal indigestion is a motility disorder affecting forestomachs like the rumen and reticulum, and simple dietary indigestion is a nonspecific GI upset not confined to the abomasum. So the condition that directly targets the abomasum is abomasal ulcers.
