Figure 6.

Representative images showing gastric ulceration in a transported horse at T0 (before departure), T1 (immediately on return from transportation) and T3 (60 hours after transportation). Ulceration was attributed to splashing of liquid content against the gastric mucosa, and was particularly marked in horses fasted before transportation for placement of indwelling nasogastric tubes. All images show the greater curvature of the stomach. At T0 there is hyperkeratosis only (grade 1). At T1 there is extensive ulceration extending from the margo plicatus, with bleeding evident in some affected areas (grade 4 of greater curvature and fundus). By T3 the affected area appears less inflamed and ulcers are no longer bleeding; however, extensive ulceration is still apparent, and remains deep in some affected areas (grade 4)
