چکیده
Ileal impaction is prevalent in the south-eastern USA, where feeding of Coastal Bermuda hay has been implicated as a risk f a c t o r. A l t e r n a t i v e l y, infection with the tapeworm Anoplocephala perfoliata has been identified as a risk factor f o r ileal impaction in the UK. We hypothesised that feeding Coastal Bermuda hay and failure to administer routinely an anthelmintic with efficacy against tapeworms would place horses at risk of developing ileal impaction in the USA. Seventy-eight horses, with surgically confirmed ileal impaction and 100 horses admitted for colic that did not have an ileal impaction, were selected re t rospectively for logistic re g re s s i o n analysis. Using odds ratios (OR) as an index of risk, feeding Coastal Bermuda hay (OR = 2.9) and failure to administer a pyrantel salt within 3 months of admission (OR = 3.1) placed horses at risk of development of ileal impaction. This study confirms the belief that feeding Coastal Bermuda hay places horses at risk of ileal impaction, although the quality of the hay may also play a role. Periodic administration of anthelmintics with efficacy against tapeworms should be considered to reduce risk of ileal impaction.

Impaction of the stomach typically consists of excessive dry, fibrous ingesta, but may also be composed of ingested materials that form a mass, such as persimmon seeds or mesquite beans. 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 im...

Acute as well as chronic and recurrent colic episodes were caused by right dorsal colon (RDC) impaction in 7.98% of all colic patients. Significantly higher statistical evidence was figured out in hucul horses, mares and 7-year-old animals. Diagnosis of RDC impaction was established on the basis of rectal palpation (68.75%) or laparotomy (31.25%). Yield of rectal palpation was limited by a diff...
