Two horses were evaluated in this study. One horse was a 10 year old Sorrel Quarter Horse mare that competed in barrel racing and the other an 8 year old Bay Standardbred Gelding Pacer who competed in harness racing. Both were actively complete at the same of the study. Both horses were provided the recommended amount of oil during the study. Both horses were fasted overnight (14 hours) and sedated with 4 mg detomidine HCl intravenously prior to passage of a 3m Olympus video scope into the stomach. The stomach lesions were scored on a scale of 0 to 4. The Gelding was re-evaluated aYer 20 days and the Mare aYer 35 days on the product. During this time, neither horse received any other products or supplements.
On initial examination, the Gelding scored a 3 on the ulcer scale with multiple small to medium sized ulcers at the margo plicatus throughout the stomach. The lesions appeared to be chronic in nature with a thickened edge. Mild bile staining was also present. After treatment with the product, the ulcer score was reduced to a 1 and no bile staining was present. One can see the healing ulcers at the edge.

On initial examination, the Mare had an ulcer score of 2 with a single lesion at the margo plicatus on the greater curvature of the stomach. After treatment, the lesion was 90% resolved.

It would appear from this study that the product may have a place in the treatment of equine squamous gastric ulceration, however, many more horses would need to be evaluated along with control horses to make this conclusion. Other horses were going to participate in the study, however when the trainer realized the extent of ulceration, he was unwilling to treat solely with the product and added omeprazole thereby disqualifying those horses from the study. Anecdotally, both horses above had improved performance, however, it is well known that the addition of oil can have marked effects on muscle physiology and ergonomics in horses (particularly Standardbreds and Quarter Horses) so it is unknown whether the improvement in performance was due to changes within the stomach or other physiological changes.
Thank you for allowing me to participate in this study. Feel free to contact me if you have any questions. Best Regards,
