Hw is cow able to give milk through out its life..where as human only during pregnancy..?

Question

Ie cow starts providing milk soon after it givig birth to its first calf & continous to do so even after its delivery period but why not in humans.......

Answer 1

Cows don't produce milk for a lifetime.

Like humans, cows produce milk only after they have given birth. They continue to produce milk for about 44 weeks, at which point their natural lactation cycle usually comes to an end. Only when a cow gives birth again can it produce more milk. Near-constant production of milk does not come naturally to a cow, though industrial dairy farming techniques have now made this a possibility.

To increase the amount of milk generated by a cow, the dairy industry has used selective breeding, heavily concentrated, high protein feed, increased exposure to light, and most recently the artificial growth hormone rBHG.

Once a cow can no longer produce milk, she is no longer a source of income, and will be sold for slaughter.

Answer 2

This is how it works; When a woman is pregnant the mammary glands stimulate the production of milk for the coming baby. 3 to 4 days after birth the lady start producing milk.
This last for as long as the baby sucks from the breast.
So if you stop breast feeding as early as a month, your system will stop producing milk as there's no demand for it. Or is you choose to breastfeed for 2 years you produce the milk since there's demand.

In shot: Supply and demand.

We milk the cows everyday, threfore there's demand and the system will continue producing....

got that?
good...

Answer 3

Because it is being milked constantly. If women kept breastfeeding longer, they would still produce milk
As creepy as it sounds, there is women who breastfed their kids until they were 6 or 7- especially in poor regions of the world, where food is scarce and water is polluted. On the other hand, ask any farmer, and he'll tell you that cows stop producing milk if they are not milked every day- the pulling and emptying of the mammary glands stimulates production of milk both in cows and women (and all mammals).
So there's no difference

Answer 4

Cows are made to have calves every year , the calves are then taken off them very early on and the farmer milks them, so that milk is still produced. It's acttually really cruel, and this is why they constantly produce milk, by giving birth to a new calf each year

Answer 5

As the informed posts said, a woman produces milk as long as the breastfeeding continues. A woman can become pregnant again while breastfeeding an older child, and produce enough milk to feed them both if she chooses to. As a child grows older and has other foods in his/her diet, the milk production lessens in accordance to how often the child feeds at the breast. Again, lactation does NOT have a set end time; the milk ducts slowly dry out once breastfeeding has ended.

Answer 6

Because the cow is continually milked twice a day. If the human kept pumping out her milk she would go on as well.

Answer 7

Who says women cant continue producing milk long after delivery? I've heard of women with 7 year olds still nursing. It's a matter of supply and demand.

Answer 8

Actually, women can produce milk for years after giving birth. Most women aren't milked and don't usually let their children breast feed after a certain point. There used to be an occupation called wet nurse for women who wanted to breastfeed for years.

Answer 9

i work for a company which makes long life milk packages and we sell half a billion litres of milk a year they are using hormones to make the cow produce more milk.

Answer 10

I produced milk for four years after my daughter was born, long after she quit nursing, although it wasn't much. I'm currently on month 21 of nursing my son. As the others here have said, after birth a woman will produce milk for as long as there's emptying of her breasts. It's a demand and supply situation, not a supply and demand.

Moooooo.
