Effects of dietary beta glucan administration on humoral parameters of fish sampled during the nutrient test on D15 and D36, or 2 days after bacterial infection (D39). (A) Plasma hemolytic alternative complement activity. (B) Plasma total immunoglobulin’s content. (C) Plasma lysozyme activity. (D) Respiratory burst activity (RBA) of spleen macrophage cells. Values are expressed as mean ± SD of 18 fish/diet/day on D15, D36 and 9 fish/diet on D39. For spleen respiratory burst activity (RBA), plasma hemolytic alternative complement activity (ACH50) data are expressed as mean ± SD of 9 fish/diet/day on D15, D36. Statistical differences between groups are indicated by different letters Statistical differences, highlighted by letters, are indicated for glucan concentrations in front of 0, 0.2, and 0.5% next to the corresponding plot, for glucan type by letter above the horizontal bar grouping the two doses of the same glucan, for glucan type × concentrations interactions above each box. P values are shown at the bottom of each graph at a given timepoint (D15, D36, or D39).
