Title: | Distribution of antibodies against porcine circovirus type-2 (PCV2) in single site and multi-site farrow-to-finish farms in Brazil | Contributor(s): | Gerber, Priscilla Freitas (author) ; Galinari, Grazielle C F (author); Silva, Marcos X (author); Campos, Fabia S (author); Reis, Adrienny C T (author); Lobato, Zelia I P (author) | Publication Date: | 2009 | DOI: | 10.1016/j.rvsc.2009.04.013 | Handle Link: | https://hdl.handle.net/1959.11/21253 | Abstract: | A comparative serologic study was performed in seven single site (SS) farrow-to-finish farms and four multi-site (MS) farrow-to-finish farms, with or without post-weaning multisystemic wasting syndrome (PMWS). In each farm, 30 blood samples were collected for each category of the production cycle: sows, farrowing crate, nursery, grower pigs, and finishing pigs. Sera were evaluated for the presence of antibodies to porcine circovirus type-2 (PCV2) via immunoperoxidase monolayer assay. Serologic profiles for PCV2 were different between SS and MS farms. Seroconversion following the decline in maternal antibodies occurred at a later stage on SS farms (grower pigs) than MS farms (nursery pigs). MS farms tended to have lower antibody titers than SS farms in the categories of sow, piglet, and nursery, while higher antibody titers were found in grower pigs. Characterization of serologic profiles for different farms may provide important information for the adoption of vaccination programs. | Publication Type: | Journal Article | Source of Publication: | Research in Veterinary Science, 87(3), p. 488-491 | Publisher: | Elsevier Ltd | Place of Publication: | United Kingdom | ISSN: | 1532-2661 0034-5288 |
