Which statement is true about Type 2 vagal indigestion as compared to other vagal indigestion syndromes in cattle?

• A. It is the most common cause of vagal indigestion syndrome in adult cattle
• B. It is caused primarily by inflammation of the vagus nerve
• C. It results from hypermotility of the reticulorumen
• D. It is never associated with traumatic reticuloperitonitis

Answer: (A)

Vagal indigestion patterns reflect how the fore-stomach motility is disrupted by vagus nerve dysfunction. Type II is the form most commonly seen in adult cattle, and it typically stems from disruption of vagal innervation—often following traumatic reticuloperitonitis. This leads to reduced (hypomotor) reticulorumen activity with persistent distension, rather than excessive movement. The idea that it’s caused mainly by inflammation of the vagus nerve isn’t accurate, and hypermotility isn’t the hallmark of this type. Traumatic reticuloperitonitis is a well-known antecedent, so it is not correct to say there’s no association with TRP.
