This study was carried out to investigate the dietary effects of β-glucan and single-species probiotics on growth performance, antibody production and cecal microbial profiles in broiler chickens. A total of six hundred thirty 1-d-old male broiler chicks were divided into seven groups and fed one of seven non-medicated experimental diets containing β-glucan (0.025, 0.05 or 0.1 %) and probiotics (0.05, 0.1 or 0.2 %) or devoid of them for 5 wk. The body weight gains of the birds fed diet containing 0.025 or 0.1 % β-glucan, 0.1 % or 0.2 % probiotics were significantly higher (p<0.05) than those of the birds in the control The antibody titers against Newcastle disease virus(NDV) or infectious bronchitis virus(IBV) in chicks fed diets containing β-glucan and probiotics were significantly higher (p<0.05) than those of control.
