Prevalence of gastric lesions in foals without signs of gastric disease: an endoscopic survey.

The research is about the prevalence of gastric lesions in Thoroughbred foals without visible gastric disease symptoms in England and Ireland. The investigation found no significant differences in lesion prevalence based on location, gender, or age amid all tested variables.

Methodology and Sampling

• The researchers performed gastroendoscopic examinations on a variety of 75 thoroughbred foals, whose age ranged from 2 to 85 days. These foals were situated in seven different breeding farms across England and Ireland.
• Despite lacking visible signs of gastric disease, these foals were subjected to the examinations.

Prevalence and Location of Gastric Lesions

• The study found that the difference in the prevalence of gastric lesions in foals from England and Ireland was statistically insignificant. With 57% in England and 47% in Ireland.
• Neither sex showed more predisposition towards lesion prevalence with 50% of males and 51% of females expressing signs.
• Regarding age, younger foals that were under 10 days old showed a higher prevalence of lesions, with 88.9% being affected. On the contrary, foals older than 70 days showed the least prevalence with only 30% being affected.
• In observing lesion locations, a clear trend was noticed. The squamous mucosa along the margo plicatus on the greater curvature of the stomach was the most frequent site for lesions, accounting for cases in 34 foals. Conversely, squamous fundus, glandular fundus, and the lesser curvature were less implicated, with cases seen in 11, 6, and 3 foals respectively. No lesions were found in the squamous mucosa surrounding the cardia or the stomach’s opening.

Lesion Prevalence and Health History

• Of notable importance was the finding that foals with previous health issues exhibited a higher prevalence of gastric lesions (68%) in contrast to those without any prior health problem (43%).
• Particularly, foals with a history of diarrhea were found to have a high likelihood of lesions, with approximately 64% of the 14 foals researched showing signs.

This research provides vital insights into the prevalence and positional tendencies of gastric lesions in Thoroughbred foals. It also illustrates potential links between lesions occurrence and previously experienced health disorders, despite the absence of obvious gastric disease symptoms.
