Breeding characteristics of raccoon dog in Ursuli

1. Sexual maturity: the young raccoon dog is sexually mature at the age of 8-10 months after birth, and the male raccoon dog is slightly earlier than the female.

2. Sexual cycle: raccoon dog is an animal in estrus once a year. The testis of male raccoon dog begins to develop from the Autumn Equinox, and the texture of testis is soft at the end of January and the beginning of February. There are mature sperm in the epididymis, which begin to show sexual desire and can mate. The whole mating period can last 60-90 days. The testis atrophied quickly after the end of the mating period, and returned to the quiescent state in May, until the Autumn Equinox developed again, showing annual periodic changes. The sexual organ development of the female raccoon dog is similar to that of the male raccoon dog, and there are mature follicles and eggs in the ovary from the beginning of the Autumn Equinox to the end of January and the beginning of February of the second year. The whole estrus lasts from the beginning of February to the first ten days of April. After mating, the pregnant female raccoon dog enters the pregnancy period and gives birth to lactation. The non-pregnant mother raccoon dog and the weaned mother raccoon dog returned to the quiescent period until the sexual organs of the autumnal equinox developed again, showing annual periodic changes.

3. Mating behavior: during estrus, the male raccoon dog gets close to the female raccoon dog and smells the female's vulva. When the male raccoon dog climbs across the female raccoon dog, the female raccoon dog tilts its tail to one side and stands waiting for the male raccoon dog to mate. The male raccoon dog climbs over the back of the female raccoon dog, and the hindquarters shake frequently to mate, then the buttocks are sunken, the two forelimbs clasp the mother raccoon dog waist, stop for 0.5 minutes, and the tail root flaps gently is ejaculation. After ejaculation, the female raccoon dog turns the body relative to the ventral side of the male raccoon dog for a period of time (ranging from 1 to 30 minutes), and then separated, that is, mating is successful. In order to ensure that the mother raccoon dog conceives, it should mate once a day for 3 consecutive days.

4. Pregnancy: calculated according to the first mating day, the gestation period of raccoon dogs is 54-65 days, the pregnant mother becomes gentle and calm, the appetite increases day by day, the fetus can be touched outside the abdomen on the 30th day of pregnancy, and the abdomen droops slowly on the 40th day, plucking and making nests before labor, curled up in the chamber, unwilling to go out.

5. Giving birth: most babies are born in a small room at night, with a delivery duration of 4 to 8 hours, and some for 1 to 3 days. after giving birth every 10 to 15 minutes, the mother bites off the umbilical cord and eats the placenta, licks the body of the raccoon dog, and does not breast-feed until after giving birth. In some cases, the babies were born in batches in 2 to 3 days, with an average of 9 babies, up to a maximum of 18.

6, mother and baby behavior: the mother raccoon dog can pull out the quilt around the breast before delivery, so that the nipple is exposed, the maternal nature is very strong, not out of the small room after delivery, breast-feeding at ease. Newborn babies can crawl to find nipples to suck after 1-2 hours of plush drying, and then fall asleep after eating, usually sucking once every 6-8 hours. Raccoon dogs grow teeth at 15-20 days old and begin to feed. At 45-60 days old, raccoon dogs can be weaned and live independently. Raccoon dogs grow up to be adults at 5-6 months old.
