In fact, there is no obvious seasonality in rabbit breeding. The temperature is low and stable in winter, the air is dry, the activity of some pathogenic microorganisms is inhibited, rabbit disease is relatively reduced, and the survival rate of puppies is higher. Rabbits can also breed in winter as long as they are properly managed.
In order to breed winter breeding, you should choose the dominant species that have strong cold resistance and long feeding time in the local area. The breeding male rabbit should reach 8-10 months of age and weigh more than 3.5 kg; the breeding female rabbit should be 6-8 months old and weigh 3 kg. the above. Rabbits are required to have full appearance, body length, back flatness, quick action, normal appetite, thick limbs, shiny hair, well-developed, strong sexual desire, and good semen quality; female rabbits require strong physique, gentle temperament, and good genitals. The anal genitals are free of contaminants, and the estrus is normal. The nipples are no less than 4 pairs, and they will pull grass mats, will suckle, have good motherhood, have lots of babies, and have good physique.
The clever aphrodisiac should pay attention to the rabbits in the sun in order to increase sexual desire and stimulate ovulation. For female rabbits that are not estrus or have no obvious estrus, artificial aphrodisiacs should be used, such as provocative and tempting methods. When the female rabbit does not have estrus or refuses mating, the female rabbit can be placed in a male rabbit cage. After the male rabbit is chased and crawled for 1-2 hours, it is then returned to the original cage, usually after 3-4 times. Female rabbit estrus. In addition, female rabbits and male rabbits are reared in cages, or female rabbits are placed in cages raised with male rabbits. Special odors released by female rabbits can induce estrus in female rabbits. You can also use vitamins, herbal aphrodisiac and other methods.
Clever mating winter female estrus time interval is long, love period is short, we must pay attention to observing female estrus performance. When the mother rabbit is excited and uneasy, she runs and jumps in the cage, loses her appetite, suffers from loss of appetite, frequently raises her tail, climbs across other rabbits, and actively approaches the male rabbit. When the vulva is swollen, flushed, and moist, breeding is most appropriate. It is advisable to adopt a compounding method for the breeding method, that is, after the first breeding, 7-8 hours apart, and then mating with the same male rabbit once, so that the quantity and quality of sperm required for the fetus can be guaranteed. Male rabbits and female rabbits are brought up in time to raise the female rabbit's buttocks and take two shots by hand to promote contraction of the vagina and uterus to prevent the outflow of semen.
Qiao feeding (1) ensure nutrition. Regardless of whether it is a male rabbit or a female female rabbit, it is necessary to maintain a medium sensation, and feed should strive to diversify.

Wheat, soybeans, etc., if necessary, can also supplement trace elements such as zinc, which have a great effect on reproduction, and supply various vitamins appropriately. After the female rabbit is pregnant, it is appropriate to increase the nutrient content of the feed and feed more feed such as carrots and bean cake. After being weaned, the pups gradually reduce the amount of concentrate fed to prevent the occurrence of mastitis due to excessive lactation.
(2) Strengthen management. The most suitable temperature for rabbits is 15-25°C. Below 5°C, female rabbits are not only estrus but may even get sick. Therefore, the rabbit house must be built in the leeward, sunny, warm place, the temperature is controlled above 10 °C. In low temperature, rain and snow weather, rabbit house curtains should be hung at the entrance of the rabbit house, soft grass should be laid in the house, and the place where the wind and snow enter the snow should be blocked tightly; avoid burning in a rabbit house to prevent gas poisoning or cause respiratory diseases. When the weather is warm, you can put your rabbit out and exercise more. Periodically clean the rabbithouse and keep the house dry. The relative humidity is controlled between 50% and 60%. If the house is damp, the wood ash or lime can be dampened and sterilized.
