It is generally believed that spring and autumn are the golden season for rabbits to breed and breed, while winters are not suitable for breeding. In fact, there is no obvious seasonality in rabbit reproduction. In winter, the temperature is low and stable, the air is dry, the activity of some pathogenic microorganisms is inhibited, rabbit disease is relatively reduced, and the survival rate of puppies is increased. As long as the rabbit is properly managed, rabbits can also be Winter breeding. Clever selection of species: winter breeding, should choose strong cold resistance, in the local long feeding time of the species, and breeding male rabbits should reach 8 to 10 months of age, weighing 3.5 kg or more; female female rabbits 6 to 8 months of age, weight 3 More than kilograms. 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; the female rabbits require strong physique, gentle temperament, and good reproductive organs. The anal genitals are free of contaminants, normal estrus and no less than 4 pairs of nipples. Clever aphrodisiac: winter should pay attention to let the rabbits more 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 performed: (1) tease. Place the female rabbit in a rabbit cage and let the male rabbit chase and crawl for 1 to 2 hours. Generally, the female rabbit can be estrus by 3 to 4 times. In addition, female rabbits and male rabbits are reared in cages, or the female rabbits are placed in cages that have raised male rabbits. The special odor released by male rabbits can also induce estrus in female rabbits. (2) Tap and massage the genitals. Raise the tail of the female rabbit and quickly beat the genitals rhythmically with appropriate force, 1 to 2 minutes each time; or gently massage the female vulva by hand for 4 to 5 minutes each time. When the female rabbit voluntarily raises the tail, immediately send it. Into the male rabbit cage mating. (3) Feeding malt. Two to three days of germination of wheat were mixed into the feed to feed the female rabbits, fed 2 times a day, 20 to 30 grams each time, and fed for 3 days. (4) Feeding carrots. Stir the carrots into the feed twice a day for 50 to 100 grams each time. After two days, the female rabbit will be in heat. (5) Take vitamins. Each female rabbit was given oral vitamin E 1 to 2 capsules daily for 3 to 5 days, and the effective rate was 90% or more. (6) Apply iodine. The vulva of the female rabbit was smeared with 2% iodine, and the effective rate was above 80%. (7) Chinese herbal aphrodisiac. Oral Chinese herbal epimedium 10 grams, fed twice a day in the morning and evening, once every 3 days. (8) hormone aphrodisiac. Intramuscular injection of maternal serum gonadotropin, a 100 units; or intravenous injection of chorionic gonadotropin, 80 units at a time, generally 2 to 3 days after the injection can be estrus breeding. Clever mating: winter female estrus time interval is long, love period is short, we must pay attention to observing female estrus performance. When the female rabbit is excited and uneasy, he runs and jumps in the cage, loses appetite, loses appetite, frequently raises his tail, climbs other rabbits, and actively approaches the male rabbit. When the vulva is swollen, flushed, and moist, breeding is most appropriate. The method of mating should adopt the compounding method, that is, after the first breeding, interval 7 to 8 hours, and then use the same male rabbit to mate once, so that the quantity and quality of sperm required for fetuses can be guaranteed. After the mating, the female rabbits are lifted in time to take the buttocks and take two shots to urge the vagina and uterus to contract and 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 be diversified. On the one hand, it is necessary to ensure the supply of green and juicy feed, on the other hand, a certain amount of concentrate feed must be properly added, and if necessary, it can be supplemented. Reproduction of a large role of zinc, manganese, iodine and other trace elements, and appropriate supply of a variety of vitamins.

In the low temperature, rain and snow weather, the straw curtains should be hung at the door of the rabbit house, soft grass should be laid in the house, and fire should be avoided in the rabbit house to prevent gas poisoning or 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. (3) Careful care. After the pups were born, they were given brown sugar water and saline to prevent their thirst from eating puppies. The puppies are 16 to 19 days old and can start feeding. In the early stage, they can feed a small amount of soybean milk and rice soup, and then add wheat flour and bean dregs. After 6-7 days, you can mix in mineral feed and feed some carrots. Feed 4 to 5 times a day and feed them once at night. Let the young rabbits exercise more and take more sun to increase the survival rate. The pups can be weaned after 30 days of age, and generally have large, well-developed individuals with weak offspring and small individuals. (4) pay attention to disease prevention.
