Effect of dietary corn oil supplementation on equine gastric fluid acid, sodium, and prostaglandin E2 content before and during pentagastrin infusion.

This research article investigates how supplementing ponies’ diets with corn oil affects certain aspects of their gastric secretion. The findings suggest that corn oil supplementation decreases acid output and increases prostaglandin E2 and sodium outputs in the stomach. Such changes could strengthen the stomach’s protective properties and reduce risks of ulceration due to nonsteroidal anti-inflammatory drug use.

Study Design and Implementation

• The researchers used a repeated-measures experimental design, focusing on four healthy adult ponies who had been surgically fitted with gastric cannulas.
• Initially, the ponies were fed a free-choice hay diet for five weeks. Subsequently, this diet was supplemented with 45mL of corn oil daily for another five weeks.
• In order to assess the influence of this supplemental regimen, the researchers collected gastric contents under normal (basal) and stimulated (with the use of pentagastrin) conditions. These collections took place once a week during the final two weeks of each dietary phase.

Method of Gastric Content Analysis

• The gastric content collections occurred at 30-minute intervals.
• The team analyzed the volume, hydrogen ion concentration, sodium content, and prostaglandin E2 (PGE2) content of these gastric contents.
• The data was processed using a linear fixed-effect modeling procedure.

Results of the Corn Oil Supplementation

• Upon analyzing the data, the team found that under basal and pentagastrin-stimulated conditions, the ponies showed a significant decrease in acid output when their diet was supplemented with corn oil.
• Simultaneously, they demonstrated a significant increase in both PGE2 and sodium outputs.

Implication of the Findings

• The researchers concluded that corn oil supplementation could serve as an effective and cost-efficient method of enhancing the protective properties of equine glandular gastric mucosa.
• This could be particularly beneficial in reducing the risks associated with ulceration that arises from the administration of nonsteroidal anti-inflammatory drugs (NSAIDs).
