=== Developmental Anomalies ===
==== Segmental ====
Segmental anomalies of the intestines are common and range from incomplete occlusion (stenosis) to complete occlusion (atresia) of the lumen.
===== Atresia ani =====
[[Image:atresia ani PM.jpg|right|thumb|125px|<small><center>Pig - atresia ani (Courtesy of Elspeth Milne)</center></small>]]
*A common congenital defect of the lower gastrointestinal tract.
*Both the [[Anus - Anatomy & Physiology|anus]] and [[Rectum - Anatomy & Physiology|rectum]] can be affected.
*Occurs in all species but is most often seen in calves and pigs.

===== Atresia coli =====
*Considered the most common segmental anomaly of the intestine in domestic animals.
*Can affect in particular the spiral [[Colon - Anatomy & Physiology|colon]] of Holstein calves and the small [[Colon - Anatomy & Physiology|colon]] of foals.
===== Atresia ilei =====
*It is less common to see atresia in the [[Small Intestine - Anatomy & Physiology|small intestine]].
*Mostly seen in calves.
==== Persistent Meckel's diverticulum ====
*Meckel's diverticulum is a remnant of the omphalomesenteric duct of the yolk sac.
*Is usually an incidental finding though it can be associated with impaction and/or intussusception.
==== Megacolon ====
*Occurs in cats, dogs, and pigs.
*May be due to a lack of myenteric plexuses that occurs when neuroblasts fail to migrate from the nerual crest to the colorectal myenteric plexuses.
*Congenital colonic agangliosis, a condition occurring in white foals, can lead to megacolon. It is thought to be an autosomal recessive condition.
