Salivary cortisol concentrations in gilts 4 d before insemination and on gestational d 23, 65, and 107. Throughout the gestation period, gilts were fed low (6.5%), adequate (12.1%), or high (30%) protein diets, which were made isocaloric by adjusting the carbohydrate content. Values are least squares means ± SE and calculated from 10 to 12 sows per diet group. *P < 0.05 and #P < 0.1 according to the Tukey-Kramer test.

(A) Plasma cortisol and (B) corticosteroid-binding globulin (CBG) concentrations in piglets on postnatal d 27 (before weaning) and 29 (1 d after weaning). Piglets were born to gilts fed diets with low (6.5%), adequate (12.1%), or high (30%) protein levels throughout gestation, and the diets were made isocaloric by adjusting the carbohydrate content. Values are least squares means ± SE and calculated from 16 to 18 piglets per diet group. *P < 0.05 according to the Tukey-Kramer test.

(A) Plasma cortisol and (B) corticosteroid-binding globulin (CBG) concentrations of juvenile pigs before and after intravenous ACTH challenge (0.5 IU per kg BW) on postnatal d 68. Pigs were born to gilts fed diets with low (6.5%), adequate (12.1%), or high (30%) protein levels throughout gestation, and the diets were made isocaloric by adjusting the carbohydrate content. Values are least squares means ± SE calculated from 13 to 23 animals per diet group.

(A) Plasma adrenaline (ADR), (B) noradrenaline (NA), (C) cortisol, and (D) corticosteroid-binding globulin (CBG) concentrations of juvenile pigs before and after intravenous insulin challenge (0.5 IU per kg BW) on postnatal d 70. Pigs were born to gilts fed diets with low (6.5%), adequate (12.1%), or high (30%) protein levels throughout gestation, and the diets were made isocaloric by adjusting the carbohydrate content. Values are least squares means ± SE calculated from 13 to 23 animals per diet group.
