do cows produce milk all the time or only when they have given birth to calves?

Answer 1

You have some interesting answers out there.

Yes, a cow must become pregnant before it can produce milk.
Yes, they are milked daily to continue the need for milk (most farmers milk twice daily, but some three times a day). As long as there is a need for the milk, the cow will continue to produce it (over 20,000 lbs each year). However, cows go through a "dry" period where they do not produce milk - after one calf and before another. Normally, the cows undergo artificial insemination to impregnate them again. Female calves may be kept, males may be sold and raised for beef. Some are kept to use as "studs."

Most of us drink milk, eat hamburger, and wear or use some kind of leather. The dairy industry is an essential part of America's economy.

Answer 2

i imagine it relies upon on the breed you're coping with. Angus and Limousine farm animals are bred to produce more effective beef and a lot less milk so as that once they do no longer have a calf they gained't produce any milk in any respect while a dairy cow will produce milk continually regardless of their present day fertility prestige. So i imagine it is all in the breeding. A heifer will grow to be a cow after it supplies beginning. So if the heifer in question is pregnant then it is going to start up generating milk formerly it supplies beginning. How quickly formerly I actually have recognize theory. That likely varies from one breed to the subsequent also.

Answer 3

In a natural setting cows will only produce milk to feed the calf. After the calf is weaned the cow will stop milk production. However, when machine milked, the stimulus to produce milk continues long after a cow would normally stop producing milk.

Answer 4

If you're talking about beef cows (there is a difference between dairy and beef cattle), a little while after a beef calf is weaned, the cow will dry up (quit producing milk). After she calves again, her milk production will start all over again. We do not milk our cows, it all goes to her baby for about 10 months until it is time to wean them. By then they are almost as big as the cow.

Answer 5

A cow must have given birth in order to begin producing milk. Then, as long as they are milked regularly, they will continue to produce milk.

Answer 6

They get feed gm grain so that the hormones in their body think that the cow is pregant but it isn't really allowing the cow to produce milk without the side effect of having calves.

Answer 7

Cows will produce milk after having a calf for about 18-months and then they will slowly stop (just like a human). Dairy farms will impregnate their milking cows about 18-months after they have a calf to ensure a steady flow of milk.

Answer 8

Mammals only produce milk after giving birth they artificially inceminate the cow make it have a baby so it will produce milk. When it stops they do it again

Answer 9

An average cow produces 90 glasses of milk each day or about 200,000 glasses of milk throughout her life.

Answer 10

Im order for them to start giving birth, they have to have given birth to a calf. After that as long as you milk them every day they should give milk all the time.
