Serum cortisol concentrations in nursery pigs 2 h post-immune challenge with lipopolysaccharide (LPS; 40 µg/kg BW, administered i.m.). (A) Serum cortisol concentration of female and male nursery pigs from sows challenged with 10 µg/kg LPS in late gestation or saline as a control, n = 48 per treatment. (B) Serum cortisol concentration of female and male nursery pigs from sows fed diets supplemented with microalgae (AL), fish oil (FO), or a control diet (CON), n = 32 per treatment. Results are presented as LSM ± SEM. ^a,bDiffering letters above bars denote significant differences (P < 0.05).
