  1. Score 0 = normal mucosa, 1 = mild hyperkeratosis covering less than 50% of the surface, 2 = severe hyperkeratosis covering more than 50% of the surface, 3 = hyperkeratosis with few erosions, 4 = hyperkeratosis with several erosions, 5 = hyperkeratosis with many erosions or ulceration, n = total number of investigated pigs’ stomachs per age group. The data are shown as the percentage of pigs showing a certain lesion score.
