Prolific female rabbits is an effective way to improve feeding efficiency. So, how to give birth to female rabbits? Relevant studies have shown that the mating time of female rabbits is the key to determine the sex of future offspring.

The experiment showed that the former mating method gave birth to 9 litters and 68 rabbits survived, of which 57 were females, accounting for 83%. Using the latter mating method, 21 rabbits survived in 3 litters, of which 18 were male rabbits, accounting for 85%.
