Oxytocin
prolactin
Increased levels of oxytocin released from the pituitary gland of the hypothalamus in the brain increase milk production, and consequently "lets the milk down" into the teat canal where a baby can suckle from.
The let-down reflex is triggered by the hormone oxytocin, released by the pituitary gland in response to the baby suckling at the breast. Oxytocin causes the muscles around the milk-producing cells in the breast to contract, pushing the milk into the milk ducts for the baby to feed. Emotional and physical relaxation also play a role in the let-down reflex.
Oxytocin is the hormone that stimulates milk let-down in female mammals. The pituitary gland is responsible for the release of this hormone, as is the suckling action of the young and the fact the mother does not feel any stress, as this affects milk production.
If the woman is sexually active and her partner is sucking the breast as hard as a baby, the "let down" reflex is stimulated and the brain will let down milk. The soreness may be from the partner sucking too hard.
No. Stress REDUCES milk production. A stressed out cow won't produce as much milk, nor will she even let down any milk when it's milking time.
cause the server may be down.
'Cause you don't want to be let down. :(
Oxytocin
None. Calving is too stressful an event to let a cow give milk during such an event. Afterwards, and only afterwards, will she be able to relax enough to allow milk-let-down to commence.
A warm cloth or warm shower will help the milk "let down" or release, but it will not help produce milk. Milk production is caused by stimulation of the breast such as the baby suckling, manual expression, or use of a breast pump.
A cow will start to develop milk secretion cells about 6 months into pregnancy, however, she will start to let her milk down into the milk cisterns and into the teats about two days before she is ready to calve.
