  1. 1RBC: red blood cell counts; HGB: hemoglobin level; HCT: hematocrit values. High-oxygen: chickens were reared in a room with oxygen percentages between 25.8% and 26.5%; Low-oxygen: chickens were reared in a room with oxygen percentages between 20.7% and 21.4%. CON: chickens were fed basal diet; AUR: chickens were fed basal diet supplemented with aureomycin (50 mg/kg diet); PRO: chickens were fed basal diet and inoculated with L. plantarum (109 CFU/chicken) by gavage on day 1. 2SEM: standard error of a mean (n = 6 pens per treatment group). a,bDifferent superscripts indicate significant differences (P < 0.05).
