Effect of Sophy β-Glucan on Immunity and Growth Performance in Broiler Chicken

This study was carried out to determine the effect of Sophy beta-glucan on immunity and growth performance in broilers. One group was treated with 1% beta-glucan ad libitum with water and the other group was kept as the control. Vaccination for Infectious Bursal Disease was carried out on days 16 and 21. Blood samples were collected from birds, and antibody titres against IBD were measured. The mean body weight of the beta-glucan treated group was significantly (P<0.05) higher than that of the control group. The mean antibody titres measured on days 25, 36 and 42 were significantly (P<0.05) higher in 1% beta-glucan treated group than that of the control group, suggesting the presence of immune stimulating effect of beta-glucan.
