Resumo: | The effect of including mannanoligosaccharides (MOS) and/or enzymes in broiler diets on antibody titers against infectious bursal disease virus (IBDV) and Newcastle disease virus (NDV) was evaluated. A total of 750 broilers were distributed into a completely randomized experimental design in a factorial arrangement 2 x 2 + 1 with two levels of MOS (0 and 0.1% until 21 days and 0.05% from 22 to 42 days of age), two levels of enzymes (0 and 0.05%) and a positive control diet containing antibiotic, totaling five treatments with five replicates each. For antibody analyses, blood samples were weekly collected by jugular vein puncture in the same two birds per replicate. The first and last collections were done at 7 and 42 days of age, respectively. The inclusion of MOS resulted in increased antibody titers against IBDV in the fourth (P&lt;0.03) and fifth (P&lt;0.02) weeks, and against NDV in the third (P&lt;0.01), fourth (P&lt;0.03) and fifth (P&lt;0.03) weeks of age. MOS was effective in stimulating the humoral immune responses against IBDV and NDV vaccine viruses.
