Which type of colic is characterized by blockage of the intestinal tract with normal ingesta?

Colic in horses can present in various forms, with different underlying causes. When considering the characteristic of blockage of the intestinal tract with normal ingesta, impaction colic is the most accurate description.

Impaction colic occurs when the intestines become obstructed due to a build-up of material, such as food or other debris, that blocks the passage of ingesta. This type of blockage is often seen in situations where there is inadequate water intake, sudden changes in diet, or feeding of dry hay without enough roughage. Because normal ingesta cannot move past the blocked section, it leads to discomfort and distension in the horse's abdomen.

In order to differentiate this from other types of colic:

• Displacement colic refers to a condition where a section of the intestine shifts from its normal position, which can also cause obstruction but is not primarily characterized by ingesta blockage.

• Inflammatory colic typically involves conditions like colitis, which may lead to fluid build-up or swelling rather than a blockage caused by normal content.

• Obstruction colic is a broader term that could include various types of blockages, but it does not specifically indicate the normality of the ingesta involved.

Thus, impaction colic
