Concentrations of IGF-I (A) and TNF-α (B) in plasma of weanling piglets fed diets with vegetable oil (Control, n = 20) or n -3 PUFA ( Omega , n = 20). Plasma IGF-I concentrations were affected by the growth phase (P < 0.01), but not the dietary treatment (P > 0.44). Plasma TNF-α concentrations were affected by the dietary treatment (P < 0.01), but not the growth phase (P > 0.28).
