Technical measures for autumn breeding of rabbits

It is dry in autumn, with sufficient feed and rich nutrition, which is suitable for the breeding of improved rabbits. The following technical measures can be taken to grasp the autumn propagation of improved rabbits:

Rabbit breeding

1. Improve the environment and manage it carefully:

After entering autumn, strengthen the ventilation of the rabbit house and keep it clean and quiet. If a three-story cage is used, the male rabbit should be raised in the lowest cage. Because the cage temperature in the lower layer is lower than that in the upper layer, the male rabbit can also be raised in the semi-basement. In high-temperature shrimp, the testicles of male rabbits are reduced by 60%, and it takes 45 days for male rabbits to recover after the temperature drops, while female rabbits can resume breeding in about 7 days. This method is conducive to maintaining good semen of male rabbits and can increase at least 1 to 2 litters of young rabbits.

2. adjust the feed and speed up the re-fattening:

The autumn morning and evening is cool, the rabbit appetite is enhanced, feed the mixed concentrate in the morning and evening, the concentrate accounts for 65% of the diet in the evening, and provide clean drinking water, other time, feed high-quality green roughage. After fattening, feed more protein-rich feeds such as soybeans, wheat bran, fish meal, germinated barley, silkworm pupa powder, etc., the mixed concentrate contains digestible energy 2900 kcal / kg, crude protein 18%, crude fiber 10%, and add 1% salt and 2% bone meal or flour.

3. Pay close attention to mating:

After breeding in autumn, master the oestrus period of female rabbits (estrus once in 7-15 days, lasting 3-4 days each time), and breed in time. When the female rabbit is in estrus, the vagina is red and swollen, and the vagina flows out of mucus, making a "goo" sound and running around. At this time, it is necessary to grasp the mating time of "pink early, purple late, bright red", that is, when the female rabbit's vulva is bright red, it can increase the conception rate and realize double mating (two male rabbits are mated successively in the same estrus or the same male rabbit is mated again after 8 hours).

4. artificial aphrodisiac:

Common methods: drugs, teasing, information and so on. Drug-induced estrus can be injected into the medial thigh muscle of female rabbits with 50-100 units of chorionic gonadotropin and mated 4-6 hours after injection. Teasing and oestrus is to put the female rabbit into the male rabbit cage to let the male rabbit chase and climb, stimulate the female rabbit to be in estrus, usually in the morning and mate in the afternoon. The message urges the female rabbit to be caught in the cage of the male rabbit, and the male rabbit chases and climbs. After a general time, the male rabbit is caught and the female rabbit is allowed to spend the night in the cage. Because the female rabbit fully receives the smell of the male rabbit in the male rabbit cage, the female rabbit is in estrus on the second day and can be mated at this time.

5. Freezing semen and early mating:

The sexual function of male rabbits is greatly affected by high temperature, and the conception rate of natural mating is low. After the Beginning of Autumn, artificial transfusion of frozen semen can improve the conception rate. Before insemination, each female rabbit was injected with 50 100 units of chorionic gonadotropin. Insemination was performed 4-6 hours after injection, and the insemination volume was 0.3-0.5 ml.
