Breeding of Rabbit Posted on September 10, 2010 by Antony The ideal age of Buck and Doe to start breeding is 10-12 months and 4-6 months respectively. Rabbits do not ovulate on a regular cycle; as a result they do not actually go into heat. The mating of the rabbit will cause the doe to produce the eggs necessary for fertilization, usually 10-13 hours after breeding has occurred. This phenomenon is called as Induced Ovulation.
