). Measurements of total goblet cell number (full and empty) and villi height were based on the analysis of eight randomly chosen fields from the intestinal mucosa of 12 animals per dietary group. The asterisk denotes that both experimental groups are different (P b 0.001). Solid and dashed lines represent the median and mean values for each set of samples, whereas dots represent the outliers. Abbreviations: C diet, commercial feed (Aller Futura, ALLER AQUA; Christiansfeld, Denmark) used as a control; 10 IS diet: control diet containing 0.06 g LPSp kg
