Fig 3. Acquisition of antibodies in Ascaris suum-infected pigs fed grape pomace.

Levels of plasma IgM, IgA, and IgG₁ (means ± SD) specific for A. suum. Values are given for pre-infection samples (Day 0) and for 14 days post-infection in pigs fed either a control diet (black) or a diet supplemented with grape pomace (‘GP’—red). For each antibody isotype values are expressed as a absorbance units (AU). For each group n = 6.
