Fig. 2 Mean progress of body temperature (in C°; P = .013*), preputial swelling, scrotal swelling (P = .032*; scores 1 to 5), and quantity of secretion (scores 1 to 3; day 8 P = .039*, day 10 P = .032*) during study period, comparing group 1× Pen (●, n = 24) and 3× Pen (○, n = 23) with the Mann–Whitney rank sum test. Error bars show the standard deviations. The asterisks denote statistical significance.

Fig. 4 (A) Serum concentration of SAA (P < .001*) during study period comparing group 0—mild (●, n = 32) and moderate–severe preputial swelling (○, n = 15). (B) Serum concentration of SAA (P = .022*) during study period, comparing group 0—mild scrotal swelling (●, n = 37) and moderate–severe scrotal swelling (○, n = 10). (C) Serum concentration of SAA (P = .003*) during study period, comparing group 0—mild (●, n = 38) and moderate–severe quantity of secretion (○, n = 9). Error bars show the standard deviations. The asterisks denote statistical significance with the Mann–Whitney rank sum test. Journal of Equine Veterinary Science 2017 57, 86-94DOI: (10.1016/j.jevs.2017.07.001) Copyright © 2017 Elsevier Inc.
