Best Answer

Assuming you are referring to a cow that is 20 years old, then the answer to this question would be around 18 calves, if she's never had twins in her life. This is because it takes two years for a female, from birth to her first parturition, to grow old enough to produce a calf. After she has had her first calf she is able to produce an average of one calf per year. The number may be higher if she has had twins in her lifetime.

How many calves can a cow produce in her lifetime?

A cow can have anywhere from one to 20 calves in her lifetime, depending on how productive she is and how long she is able to stay in the herd to produce those calves. On average, a cow will produce eight calves in her lifetime. Cows that are used for embryo transfer can produce up to twice as many calves in her life time than she can by her own doing. The record number of calves a cow has had in her lifetime is 39.


How many times can a cow have calves?

A cow will have a calf once a year. If she goes for longer than that she gets culled. In her lifetime, well that depends on how long she lives. Heifers become cows when they calve at around 24 to 30 months of age (depending on the breed), and the average cow lives to 15 to 20 years of age, so that mean a cow will have 13 to 18 calves in her lifetime. Of course that's just average, since a heifer or cow can be culled at any age if she poses any problems, productive-, temperament- or health-wise.

How many calves could you expect your jersey nurse cow to raise If you just treated her like a beef cow and let her out to pasture with the calves and how many gallons of milk would she produce?

A jersey cow produces quite a lot of milk, much more than a beef cow does. Beef cows only produce around 10 to 20 lbs of milk per day, whereas a Jersey is capable of producing 40 to 50 lbs of milk per day. With double the milk production, she can nurse 3 to 4 calves at a time, probably even more if her lactation is kept up enough that four calves will suckle on her all at once, then another group of calves nose in to take the rest. Of course this also depends on the quality of the pasture. If the pasture is producing lush, thick grass, then she will have no problem producing enough milk for a half a dozen calves. However, if pasture is sparse, she may only have enough to nurse a couple.
