Acquisition de l'immunité passive chez des porcelets issus de truies exemptes d'organismes pathogènes spécifiques (EOPS) [Maternally derived immunity in piglets born to specific pathogen free (SPF) sows].
Journées Recherche Porcine, 2007, Volume 39, 429-430
The immunoglobulin G (IgG) content in the colostrum of eleven SPF sows was determined at regular intervals up to 36 hours after the beginning of farrowing and in the serum of their piglets up to 28 days after farrowing. The results were compared to those obtained in a previous study carried out with conventional sows. Just as in conventional sows, a significant decrease in the IgG content of colostrum was observed after 6h. In piglets, a positive correlation between average daily weight gain (ADG) at 24h and serum IgG content at 48h and 7 days post-farrowing was observed, as well as a clear birth rank effect since IgG contents were found higher in the first born piglets of the various litters.
