Mendelian trait/disorder: unknown

Considered a defect: yes

Cross-species summary: Also known as Hirschsprung disease. A disorder in which the large intestine (caecum, colon and sometimes the rectum) undergoes a large dilation and fills with faecal mass. Associated with incomplete migration of nerve cells to the intestine during embryonic development, resulting in lack of peristalsis and hence a build-up of faecal material.

Inheritance: No good family data have been published for pigs. However, this disorder is single-locus in some other species.
