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); levels 2000, 4000, and 6000 mg/kg treated groups = commercial feed, treated by cinnamon powder; ² SEM, standard error of mean for treatment effect. ³ Data are mean of eight chicks per treatment (one bird/replicate). ^a,b Mean values within rows with different superscripts are significantly different (p < 0.05).
