It depends on the type of calf. A dairy bull calf will live up to or around 4 to 6 months before being slaughtered for veal. A beef steer will live up to around 2 years of age before being slaughtered. A heifer calf kept as a replacement (who will become a cow) will live anywhere from 5 to 20 years of age, depending on her productivity. A bull calf kept as a herd bull can live to about the same age of the heifer calf kept to become a cow.

Killer whales give birth to one calf, every five years. Gestation lasts on average 15 to 18 months.
A female Oryx can calve in 9 months intervals, so she can birth 1 calf every 9 months. This is due to the Oryx females coming into heat almost directly after the birth a calf. The Oryx has single calf births.
Okapis typically give birth to one calf at a time, and females usually have a single calf every 1 to 2 years. Twins are extremely rare in okapis. The gestation period lasts about 14 to 16 months, after which the mother raises the calf primarily on her own.
Negative three to four months, assuming the cow gets bred two months after calving and the calf is weaned at six months of age. Seriously, a cow is already bred and into her second trimester when her calf is weaned. Cows are not like human females where they can only get pregnant again at least a year or 8 to 12 months post-partum.
A dugong typically gives birth to a single calf after a gestation period of about 13 to 14 months. Twins are extremely rare but can occur on occasion. The mother usually nurses her calf for about 18 months to two years, providing it with essential nutrients and care during its early development.
