Title: | The effects of sow viremia and maternal antibodies in porcine circovirus 2 on viral infection and weight of piglets | Contributor(s): | Gerber, Priscilla Freitas (author) ; Garrocho, F M (author); Lobato, Z I P (author) | Publication Date: | 2014 | Open Access: | Yes | DOI: | 10.1590/1678-41625917 | Handle Link: | https://hdl.handle.net/1959.11/21275 | Abstract: | The aim of this study was to characterize the porcine circovirus 2 (PCV2) infections in farrowing sows and to evaluate an association with piglet viremia and weight. Twenty sows and 100 newborn piglets were studied. Colostrum and serum of the sows were obtained on the day of parturition. Milk samples were collected on day 20 postpartum. Blood samples were taken and the piglets were weighed on days 1, 20, 42, 63 and 84 postpartum. Colostrum, milk and serum were evaluated for PCV2 DNA load. Serum was evaluated for neutralizing antibodies. PCV2 DNA was found in 17/20 serum samples, 14/20 colostrum samples and 11/20 milk samples. On day 1 postpartum 29% of piglets were viremic. PCV2 viral load ranged from 3.02 to 6.75 log₁₀ copies/mL considering all sampled days. There was no correlation between sow viremia, antibody levels or PCV2 load in colostrum and piglet viremia on day 1 postpartum. The PCV2 load in colostrum and milk was associated with viremia in piglets from weaning to 84 days postpartum. Piglets' PCV2 viremia and viral load could not be associated with weight throughout this study. | Publication Type: | Journal Article | Source of Publication: | Arquivo Brasileiro de Medicina Veterinaria e Zootecnia, 66(2), p. 405-410 | Publisher: | Universidade Federal de Minas Gerais | Place of Publication: | Brazil | ISSN: | 1678-4162 0102-0935 |
