For a twin pregnancy when calves are of different genders – bull vs heifer – the female (heifer) will generally be sterile due to interactions with the male hormones during pregnancy. On occasion, cows can give birth to multiple calves from one pregnancy. This is much rarer than twin births.
And most cows usually live to around 20 years old if they are not slaughtered beforehand. Theoretically, a cow could have 1 cow every year between the ages of 2 and 20, meaning they could have 18 calves in a lifetime. However, this is very rare, and most breeding cows have between 7 and 10 calves throughout their life.

How old do cows have their first calf?
Most beef cattle in the United States are managed to calve at 2 years of age, meaning they would become pregnant at approximately 15 months of age. Using the management practices described above, this cow would have her first calf at two years of age and continue to calve each year after that.
While I was writing we ran into the question “How many babies do beef cows have?”.
Unlike other livestock species that give birth to multiple offspring each pregnancy, most beef cows give birth to one calf for each pregnancy. Their reproductive tract is built to supply enough nutrition to the calf throughout pregnancy .
Another frequently asked query is “How often do cows have babies?”.
Cows have a 9 month gestation period and typically have a calf every 12 months. All cows spend their entire lives (Approx. 7-10 years) grazing on grass or forage and mothering baby calves. When they are no longer able to have calves, cows are harvested for beef (see final stage).
What is the difference between male and female dairy calves?
Female calves will become a replacement dairy cow. Male dairy calves are generally reared for beef or veal; relatively few are kept for breeding purposes. In English the term “calf” is used by extension for the young of various other large species of mammal.
What is the lifespan of a dairy cow?
Depends on what the animals are used for, their health, breeding, productivity, and even location. Dairy cows have an average lifespan of 5 to 6 years, though it’s not uncommon for cows to live past 10 years and still be productive in the herd, regardless of herd size.
How many years does it take for a cow to calve?
Using the management practices described above, this cow would have her first calf at two years of age and continue to calve each year after that.
