The present study aimed to assess the effects of three probiotic-supplemented diets on growth, cecal fermentation, blood biochemical, and intestinal morphological features in growing rabbits reared under summer conditions. Rabbits were allotted into four groups: G1 rabbits were fed the basal diet (control), G2 rabbits received (EF) and (CB) complexes (1 × 10 and 2.5 × 10 cfu/kg diet, respectively), G3 rabbits were given CB (2.5 × 10 cfu/kg diet) and yeast complexes (1 g/kg diet), and G4 rabbits received EF (2 × 10 cfu/kg diet) and yeast (1 g/kg diet). G2 rabbits exhibited the highest performances in terms of enhanced body weight and weight gain, protein efficiency ratio and feed conversion ratio (P
