Findings suggest a possible relationship among Ob-Rl and a number of hypothalamic and peripheral peptides in the development of the neuroendocrine axis and these peptides may serve as messengers that link mechanisms that regulate reproduction and energy balance.

Treatment with ACTH (100 i.u.) or hydrocortisone acetate (250 mg) twice daily for 12 days to increase cortisol concentrations blocked ovulation in all gilts. The preovulatory surge of LH was also…

Data indicate that induction of the gonadotropin surge by E2 in the gilt requires CNS input, and the action of E2 on the pituitary in the presence of unvarying GnRH pulsation may be limited to an early transient inhibition of responsiveness to GnRH, with no subsequent direct stimulation during the period of the surge.
