1 NC: negative control group = commercial feed, no additives by cinnamon powder; PC: positive control group = commercial feed, treated by antibiotic Colimox powder (mixture of amoxicillin and colistin at 200 and 150 mg/kg, respectively); 2000, 4000, and 6000 mg/kg treated groups = commercial feed, treated by cinnamon powder. 2 Data are mean of 10 well-oriented villi. 3 SEM, standard error of mean for treatment effect. a–d Mean values within rows with different superscripts are significantly different (p < 0.05). VL: villus length; VW: villus width; VSA: villus surface area; CD: crypt depth; VL/CD: villus length:crypt depth; GCD: goblet cell density, goblet cell density per 100 μm villus area (GCD/100 µm VA).
