Total serum protein (A) and immunoglobulin IgG (B), IgM (C) and IgA (D) concentrations in pigs. Piglets were born to sows fed adequate (AP, 12.1%), low (LP, 6.5%) and high (HP, 30%) dietary protein levels throughout gestation. Blood samples were taken on D1 (AP, n = 43; LP, n = 51; HP, n = 48), D27 (AP, n = 42; LP, n = 46; HP, n = 41), D80 (AP, n = 24; LP, n = 25; HP, n = 20) and D180 (AP, n = 23; LP, n = 24; HP, n = 21). Data are expressed as LS-means + SE. Significant differences between diet groups are indicated by asterisk (* P < 0.05; Tukey-Kramer test).
