Many substances including fermented feed (FF) is being evaluated as alternative to antibiotics. The aimed of this study was to investigate the effect of dietaries containing different levels of fermented feed (FF) and antibiotics on growth performance, intestinal morphology, immune status, carcass performance on slow‐growing chicken named chicken Emei black chicken. Total of 560 one day‐old broilers were randomly allocated into five treatment. The five dietary treatments were: 1) CON (basal diet); 2) AG (basal diet supplemented with bacitracin 80 mg/kg + colistin sulfate 20mg/kg); 3) I (basal diet + 2% FF); 4) II (basal diet + 4% FF); 5) III (basal diet + 6% FF), the trail last 56 days. Dietary supplementation with FF at levels of 2% significantly increased feed intake (FI) and feed conversion ratios(FCR) during 22–42 d, decreased the average daily gain (ADG ) and FI during 43–56d (P < 0.05). The diets supplemented with antibiotics significantly increased body weight (BW) compared to diets with 2% FF at day 56. On d 28, the dietary addition of FF at level of 6% significantly increased intestinal length index, villus height as well as crypt depth of ileum. The dietary addition of FF at level of 4% and antibiotic significantly increased V/C (villus height/crypt depth); the dietary addition of FF and antibiotics extremely significantly increased plasma IgG and S‐IgA (Secretory IgA) in duodenum, and also significantly increased acetic and propionate concentration in ceca; However, on d 56, the dietary addition of FF at level of 6% significantly increased abdominal fat percentage. In conclusion, it is indicated that FF has significant influence on broiler's immune system and intestinal morphology which can be used as potential alternative to antibiotics.
