The breeding stock should be chosen when they reach 4 to 5 weeks old. The breeder should be selected from the largest litter. In males, it’s very essential to find the presence of two testicles in the scrotum as testicles descend down from the body cavity at 12 weeks old.
- Extensive type of reproduction:-
Weaning here practiced is 5 to 6 weeks and re-breeding shortly after weaning. Does are therefore mated once every 2.5 months. This is the best suited for tropical countries like India.
- Semi intensive reproduction
Weaning is practised at 4-5 months old.
- Intensive reproduction
Weaning is at 4 weeks old. Mating is done immediately after kindling. Usually this practise is followed in western nations.
Always females should be put to the pen of male to avoid fighting. Mating should be performed during coolest portion of the day like early morning or late evening. After successful mating the male usually produces a typical cry sound and falls down on one side of the female. Shortly after the mating the male one should be removed from the cage. The male shouldn’t be more than 3 to 4 times in a week and not more than 2 to 3 times in a day. The proportion of male to female is 1:10. Both genders should reach 70 percent of the adult body weight.
The breeding season is almost throughout year. But in India, fall stress is encountered during hot weather.
Signs of heat in females
- Restlessness, Rubbing the chin on the sides of the cage.
- Lying in mating posture They are spontaneous ovulators. Ovulation starts 10 hours after mating.
- In heat, the female rabbit accepts male, otherwise it rejects.
- In warmth, the female assumes a typical pose known as”lordosis” in which the back is arched downward and hind quarter is raised.
- The female one in di-estrous phage crouch in the corner of the cage.
- After kindling (parturition), the re breeding happens after one week in intensive management. But normally re-mating is shown just one week before weaning.
- When temperature rises above 36 degree centigrade, temporary sterility happens.
