ARENAS, S.E. et al. Probiotic increase the antirabies humoral immune response in bovine. Arch. zootec. [online]. 2009, vol.58, n.224, pp.733-736. ISSN 1885-4494.

The effect of a probiotic on the immune response of cattle immunized with a dose of rabies vaccine was evaluated in this study. The Nellore bovines (N= 75) were divided randomly into 5 groups: supplemented with 0, 2, 3, 4 and 8 g the probiotic (Proenzime^®)/animal/day, groups Gc, G₂, G₃, G₄ and G₈ respectively, for 60 days. All the animals were immunized with a single dose of rabies vaccine on the first day of the experiment (day 0). The obtained results showed that there was significant increase (p<0.05) in the titers of antirabies antibodies and frequency of animals immunized in the groups G₄ and G₈ on 30 and 60. In conclusion, the probiotic (Proenzime^®) increase the humoral immune response of bovine immunized with rabies vaccine.
