The total ulcer surface area was measured from the photographs after considering the drawing scale. Ulcer severity was scored by the sum of the total ulcer surface area in the glandular portion of the stomach. The gastric lesions were scored between 0 and 5 according to their severity: 0 means no damage, 1 means blood at the lumen, 2 means pin-pointed erosions, 3 means 1–5 small erosions, 4 means several large erosions, and 5 means several large erosions with stomach perforation. The calculation of the ulcer score was performed according to Palle et al. (2018). The index was calculated by multiplying the average number of ulcers per stomach by the ulcer severity score and the percentage of animals with ulcers (ulcer index (UI) = the mean ulcer score of similarly treated animals × % of ulcerated animals of the group.).
