bp0018cpr14 | Maturation of The Pre-ovulatory Follicle | CPR2009
In sows, follicular development is inhibited during lactation, and
weaning the piglets allows recruitment and selection of follicles that will
undergo preovulatory maturation and ovulate. Lactation inhibits GnRH
secretion, and in turn LH secretion, through neuroendocrine stimuli
induced by suckling. Pituitary response to GnRH and the sensitivity of the
hypothalamo-pituitary unit to oestradiol positive feedback are also reduced.
