Zero.
Horses give birth to FOALS, and will generally only have one. Twins happen rarely. Never heard of triplets.
Asian Elephants normally give birth to one calf at a time, but there can be twin calves. Elephants can give birth to about 7 calves in their lives.
10 hippos at a time
A female killer whale will give birth to one calf, every five years.
None. Bulls don't "have" babies. But they can make calves by breeding a cow or two. Or more. The average offspring that a bull can sire can range from 10 to 50 calves in a breeding season. Of course this depends on the cows' ability to settle when bred and not abort.
Red deer usually have about 2-3 calves but twins are very rare.
Bison cows primarily give birth to one calf a year.
Bison do not have pups; they are mammals that give birth to calves. A female bison, called a cow, typically gives birth to one calf per year after a gestation period of about nine months. Calves are usually born in the spring and can stand and walk shortly after birth.
Cows can have one or two calves at a time. Odd time she'll give birth to triplets.
A moose can give birth to one or two calves at a time, with the average number of calves in its lifetime varying based on factors such as survival rates and reproductive success. Generally, a moose can have between 4-10 calves in its lifetime.
Horses do not produce eggs they give live birth
This is a really odd question, because, logically, a cow only gives birth once to a calf. In her lifetime she will give birth to over 10 calves.
Horses typically give birth to one foal at a time, although twins can occur, it is quite rare and often leads to complications. The gestation period for horses is approximately 11 months, averaging around 11 months and 10 days. After birth, the foal is usually able to stand and nurse within a few hours.
