EFEITO DO PROBIóTICO NA RESPOSTA IMUNE HUMORAL EM BOVINOS

This study evaluated the effect of probiotic supplementation on mineral mixture to the humoral immune response in cattle vaccinated with a single dose of rabies vaccine. Forty steers, Nellore, aged 12 months were randomly divided into 2 groups (20 animals / group): control group (CG) with 70 grams of mineral / animal / day and probiotic group (GP) with 70 grams of supplement mineral added with 4 grams of probiotic / animal. The individual titles of neutralizing antibodies were determined by neutralization technique based on the Rapid Fluorescent Focus Inhibition Test (RFFIT) and Fluorescent Inhibition Microtest (FIMT). There were no statistic significant differences between the mean serum concentrations between groups, concluding that the administration of probiotics does not interfere with the humoral immune response rabies.
