As many times as 30 Comment For the above to be true; 365/30 = 12.1 (1d.p.) days gestation. There are some marsupials with gestation periods this short, Didelphis marsupialis, Dasyurus viverrinus and Chironectes minimus. Answer For Rattus norvegicus gestation is on average 22 days and oestrus follows within 48 hour of partuition. This gives an cycle length of 24 days. 365/24 = 15.2(1d.p.) so in theory 15 litters per year is possible. In reality gestation is prolonged when the female is simultaniously lactating and pregnant so the number is probably closer to 14. The average litter size is between 6 and 12, so one female could in theory produce around 200 pups per year!
Cows are typically bred once a year, with a gestation period of about 9 months. This means a cow can be pregnant once a year and give birth to one calf annually.
There is no designated number of times that a cat needs to mate to get pregnant. Just like a human, a female cat may or may not get pregnant on the first try, or consecutive tries. However, cats can get pregnant throughout their heat cycles, and tend to keep mating. This means that it is possible for kittens in the same litter to have different fathers!
they could mate as many times as they want depending on if the male and female get into fights a lot.
Female guppies can become pregnant as early as 2-3 months old, once they reach sexual maturity. It's important to separate male and female guppies if you want to prevent unplanned pregnancies.
During the brief 3-4 day yearly period when a female raccoon can get pregnant she may mate several times, sometime with different males. She will only have one litter of kits per year as a general rule.
A female can become pregnant once each year during its breeding years.
Female rats can have a litter every 3-4 weeks. So that's once every month = 12 times a year.
3 times every year
pit bulls can get pregnant 2-3 times in a year

Only once.
If it's already pregnant, it can't get any pregnant-er. You have to wait until after delivery, and then some. It's possible, but considered unhealthy, for a dog to have two litters in one year.
