--- The persistence of the levels of maternal antibodies against the of the Classical Swine Fever virus (CSFV) in piglets born of vaccinated sows from two farms (A and B) with different vaccination programs against CSFV located in Lima valley, Peru, was evaluated. In the farm A, the sows are vaccinated at 90 days of gestation and in farm B at 18 - 21 days post furrowed. Serum samples were taken from a total of 60 piglets by farm, at first (n is equal to 15), third (n is equal to15), fifth (n is equal to 15) and seventh (n is equal to 15) weeks old and from sows from farm A (n is equal to 15) and B (n is equal to15) for antibodies detection against CSFV by indirect ELISA test. The 100% (30/30) of piglets of both farms had maternal antibodies against CSFV at first week old. In the majority of piglets the maternal antibodies persisted up to seventh week old. The levels of maternal antibodies in the piglets from both farms showed a statistically significant (p menor a 0,05) differences at first and third week old. The comparison of the maternal antibodies titers indicated more variation in piglets from farm A, a high and uniform antibodies titers were observed in piglets from farm B during the study. The sows had high level of antibodies against CSFV indicating a good passage of these antibodies to their piglets. These results suggest that the level and persistence of the maternal antibodies in the piglets depend of the management system of each pig farms. Key Words: Classical Swine Fever Virus (CSFV), maternal antibodies, piglet, sows, vaccination, pig farms.
