→Predisposing factors
Gastric impaction can occur as a primary condition but is often diagnosed at surgery as a finding secondary to other disturbances in the intestinal tract. In some cases there be predisposing causes such as ulceration or fibrosis at the pylorus, whereas in other cases it may occur spontaneously.

==Predisposing factors==
==Aetiology==
Impaction of the stomach typically consists of excessive dry, fibrous ingesta, but may also be composed of ingested materials that form a mass, suchas persimmon seeds or mesquite beans.1-3 Other feeds that tend to swell after ingestion, including wheat, barley, and sugar beet pulp, may also cause impaction. Furthermore, dental disease may increase the likelihood of gastric impaction because of improper chewing of feed. (Bliks)
===Predisposing factors===
*Ingestion of certain feedstuffs including beet pulp, bran, straw, wheat and barley - beet pulp and bran can become dessicated within the stomach and may not become rehydrated by water or gastric secretions
