Meal induced gastric relaxation and emptying in horses after ingestion of high-fat versus high-carbohydrate diets

Published: 2005-08-29

Brief content of the article
The objective of the researchers was to evaluate the effect of ingestion of a high-carbohydrate versus a high fat meal on relaxation of the proximal portion of the stomach and subsequent gastric emptying in horses. The study consisted of two phases. In phase 1, horses were offered a high-fat or a high-carbohydrate pelleted meal of identical volume, caloric density and protein content. In phase 2, meals consisted of a commercial sweet feed meal or this meal supplemented with corn oil. The authors concluded, that in horses, in contrast to other species, dietary fat supplementation might not have a profound effect on gastric motility. A full abstract can be found on Pubmed.
