ABSTRACT. This work is a retrospective study whose objective was determinate the levels of antibodies generated against bovine viral diarrhea (BVD) from immunization with different vaccine trademarks available in the market, in a farm in the district of colonia Teniente Picco, Paraguayan Chaco. For the purpose analysis records were used, that were made to bovine animals, mestizos, females of 24 months (average) distributed in 3 lots, in which lots A and B had 14 animals and lot C with 21 animals, that entered service, previous without immunization, in which the level of antibodies generated after vaccination against BVD was measured. The total titration titers of antibodies found were for vaccine A 104.9, B 94.83 and C 99.22. Analyzes were done in a private laboratory, and the results of the analyzes were used to compare the difference in antibody levels between the three commercial vaccines. The results showed that no statistically significant differences could be observed between the three groups of animals immunized with the different vaccines.
