Lactogenesis
-
Lactogenesis II
Triggered by placental expulsion, falling progesterone and oestrogen levels and presence of prolactin
-
Hormonal control
- Oxytocin from post pituitary: Milk ejection relfex - contractnio of the myoepithelial cells
- Prolactin: Anterior Pituitary gland inhibited by progesteron
- Galactopoiesis / Lactogenesis III
Switches to autocrine (hypothalamic) control
Prolactin released with nipple stimulation and removal of mil
Min 8 feed per 24 required to prevent decline of prolactin
- Early frequent feeding stimulates faster increase in milk output because it stimulatesreceptors to prolactin in the mammary glands
- Removal of mil facilitates continued production
- Milk contains whey protein - Feedback inhibitor of lactation (FIL)
- Rate of milk synthesis speeds up when mil remove and less FIL
