A female rabbit can give birth to up to 7 litters a year, with the largest litter giving birth to 1 1, and usually giving birth to 7-9 litters. So a female rabbit can give birth to 50-75 offspring a year.

The female rabbit is sexually mature in 6 months and can give birth in 7-8 months.

Suppose there is only one pair of rabbits at the beginning, and they breed 7 nests a year, each nest has 10 rabbits, including 5 males and 5 females. These little female rabbits began to breed at the age of 7 months, so by the end of the year, there were 70 offspring of the old rabbits. Among the second generation rabbits, there were 3 nests of * * * 65,438+05 female rabbits with their own offspring. Among them, five female rabbits in the first nest breed 3 times *** 10*3*5= 150, the female rabbits in the second nest breed 2 times * * 1 0 * 2 * 5 =100, and the female rabbits in the third nest breed/kloc-0.

This is only a theoretical calculation. It is impossible for all rabbits actually born to survive.

Generally speaking, herbivores reproduce faster than carnivores. The smaller an animal is, the faster it will reproduce. Rabbits are the smallest herbivores, so they breed fastest.
