This study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. Two hundred and seven days old Arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (SSB); 3) basal diet + 1% non-processed sodium bentonite (SB); 4) basal diet + 1% sulphated calcium bentonite (SCB) and 5) basal diet 1% non-processed calcium bentonite (CB). Forty birds in each group were assigned to four replicates (10 birds in each). The ratio of right ventricle to total ventricles weight (RV/TV) was significantly (P Manuscript profile
