An experiment was undertaken to verify if sows fed Saccharomyces cerevisiae boulardii (SB) produce more immunoglobulins in colostrum and milk. On a commercial farm, sows were blocked by parity and body condition 3 weeks before expected parturition. They were divided into: a control group (n=33) fed the regular farm feeding programme and an SB group (n=28), fed 25 g per day of 10% SB concentrate (5×1010 CFU/day), from the start of the trial to weaning. Colostrum was sampled just after birth of the first piglet, and 12 and 24h later, and a sample of milk was collected on day 19 of lactation.
SB significantly increased the IgG concentration of colostrum by 21% (P<0.05) and the IgA concentration by 18% (P<0.01) but did not influence IgM concentration. IgA in milk tended to increase in SB fed sows (+18%, P<0.10).
