A Botanical-Based Equine Nutraceutical Reduces Gastric Smooth Muscle Contractile Force In Vitro.

The research article explores the impact of a botanical-based equine nutraceutical on the contraction of gastric smooth muscles in pigs, in a laboratory environment. The study finds that the presence of this nutraceutical significantly reduces the contractility of the tissue which could indicate a protective use against the development of gastric ulcers in horses.

Objective of the Research

• The main objective of this study was to assess the effect of a botanical-based equine nutraceutical on the contractility of gastric smooth muscles using an in vitro method.
• The research aims to explore potential treatments for gastric ulcers which negatively influence the welfare of performance horses.

Research Methodology

• Stomachs from 12 pigs were acquired within 1 hour of their slaughter and nonglandular gastric tissue samples were prepared.
• The tissue samples were subjected to a simulated digestion process in a bath tissue, with some exposed to the extract of the nutraceutical and some without exposure.
• The tissues were stimulated with increasing doses of acetylcholine, a chemical that triggers muscle contractions.
• Measurements of Peak and mean contractile forces were taken 1 and 2 minutes following exposure to acetylcholine.

Findings of the Research

• Exposure of the gastric smooth muscles to the botanical-based equine nutraceutical resulted in a significant reduction of muscle contractility.
• The study’s findings support the prospective use of the nutraceutical to decrease contractility of nonglandular gastric smooth muscle, indicating a potential protective effect against mechanically induced gastric ulcers in horses.

Implications and Future Research

• The role of gastric hypermotility or increased gastric movements in the development of equine gastric ulcers and the specific effect of the nutraceutical on equine gastric contractility and ulcerogenesis—for instance, ulcer development—in live horses is yet to be clarified and suggests the need for more focused studies.
