Thus, although the majority of the large colon can move in the abdomen, the ventral and dorsal colons must move as a unit.

What causes right dorsal colitis?

What causes right dorsal displacement in horses?

Right dorsal displacement is thought to be initiated by retropulsive movement of the pelvic flexure with subsequent migration of the left colon cranially and progressing towards the right abdominal side until the right ventral and dorsal colon are between the cecum and right body wall (3).

What does the colon do in a horse?

Functions of the colon include absorption of water, electrolytes and short chain fatty acids. The fatty acids are the main source of energy in the horse. From the large colon, feed material takes a short passage through the transverse colon and into the small colon.

Can a horse live with a displaced colon?

Horses with strangulating large colon volvulus have been reported to have a relatively low rate of survival[13]. However, another study reported a survival rate of 83%, which is likely due to early recognition and surgical correction of the strangulating volvulus[11].

How long does it take for a horse to pass a foreign object?

The most practical approach is to monitor the horse for several days a little more carefully than usual, looking for the foreign material in the manure and watching for any signs of abdominal pain (colic), depression or inappetence.
