Body weight change (g)	0.3 (−0.5 to 1.0) (n = 10)	−4.0(−5.5 to (−3.0)) (n = 10)***
Body weight change (g/g feed)	0.02 (−0.03 to 0.04) (n = 9)	−0.3(−0.4 to (−0.2)) (n = 8)***
Disease activity index (day 7)	0.0 (0.0 to 0.3) (n = 10)	2.8 (2.3 to 3.0)(n = 10)***
Caecal wet/dry weight (g)	3.7 (3.3 to 4.5) (n = 10)	5.8 (4.7 to 6.0) (n = 10)***
Colon length (cm)	7.9 (7.5 to 8.2) (n = 10)	6.3 (5.9 to 7.0) (n = 10)***
Colon wet weight (g)	0.18 (0.15 to 0.20) (n = 9)	0.29 (0.24 to 0.30) (n = 9)***

Data are expressed as median values, range is presented within brackets. Asterisks indicate statistically significant difference from NC group: ***p < 0.001
