Fig. 1From: ACTH-induced stress in weaned sows impairs LH receptor expression and steroidogenesis capacity in the ovaryPlasma cortisol concentrations at four time points in sows of the control and ACTH groups. Plasma cortisol concentrations at four different time point (0, 16, 88, and 160 h) in the ACTH and control groups. After ACTH injection, the cortisol concentrations showed a significant increase (P < 0.01). **Values were statistically different at p < 0.01 compared to the control groupBack to article page
