Effect of algal sulfated polysaccharide (MSP extract) on the kinetics of immunoglobulin G (IgG) anti-Bordetella in the blood, colostrum, and milk of sows. (A) Levels in blood at 34 and 23 days before farrowing (−34 and −23, respectively) and at 3 and 14 days after farrowing. (B) Levels in colostrum as compared to blood level at day 23 before farrowing and in sows blood compared to colostrum. Values are given as means ± standard error of the mean (whiskers), and asterisks (*) represent significant differences (p < 0.05).
