Suplementação nutricional com probiótico com ou sem adição de zinco na produção de anticorpos séricos contra o vírus rábico em ovinos vacinados contra raiva

Abstract

This study evaluated the effect of probiotics supplementation with or without Zinc (Zn), added to the mineral mixture, in humoral immune response in sheep vaccinated with a single dose of rabies vaccines. Forty-five malecrossbred rams Santa Inês, aged 6 months were randomly divided into 3 groups (15 animals / group): Control group (CG) received 10 grams of mineral / animal / day, the probiotics group (GP) received 10 grams of mineral added 4 grams of probiotics / animal / day and Probiotics and Zinc group (GPZn) received 10 grams of mineral added 4 grams of probiótics and 14.4 mg of zinc sulfate per animal per day added to the probiotics. The individual titles of neutralizing antibodies were determined using the technique of neutralization-based Rapid Fluorescent Focus Inhibition Test (RFFIT) and Fluorescent Inhibition Microtest (FIMT). There were no statistically significant differences between the mean serum concentrations between groups. It was concluded that the probiotics administration with or without zinc did not improve the immune humoral response of antibody rabies.
