We have reported that the addition of Se to cultured bovine luteal cells increased the P4 concentration of the culture medium [26] and that the Se supplementation of non-pregnant and non-lactating cows increased their plasma P4 concentration during the estrous cycle [27], In the present study, it was clearly demonstrated that pre-and postpartum Se supplementation to the diet increased the postpartum plasma P4 concentration of dams.
It has been demonstrated that Phosphoinositide 3-kinase (PI3K)/ AKT activation plays a key role in GC survival, particularly for the survival of luteal cells (18,19).
