2. The breeding season is from March to July every year as the breeding season. From late February to early August, the scrotum of the raccoon is drooping, the skin is red, the hair is thin, the testicles are swollen, smooth and elastic, and the glans are congested and exposed. In a period of up to 5 months, the raccoon has good breeding. ability. After entering the month of August, the testicles gradually shrank. In September, the test period was reduced by 40%. In the first month, the testes began to gradually increase, with the largest testicular volume in March.
The estrous period of females ranges from late February to mid-June, with estrus occurring from late March to mid-May. During this period, female estrus can account for 87% of the entire population.
3. Estrus performance Female estrus period can be divided into four stages. In the early stages of estrus, the females were irritated, walking around, urinating frequently, redness of the vulva, loss of appetite, following the raccoon, but not accepting mating. This period was 3 to 5 days. During the prosperous estrus period, the female's labia was congested, valgused, flushed, crimson, and mucus flowed out. At this time, the siberian mating was accepted. This period is 3 to 8 days. In late estrus, the vulva shrinks, the swelling disappears, and the appetite recovers. It usually takes 3 to 5 days.
4. The mating process of civet cats occurs mostly in the middle of the night. The mating consists of the following behaviors: 1 eroticism: The mother and the mother are affectionate, chasing, and playful with each other, stimulating their sexual desires. 2 standing reaction: Due to the obsessiveness of the raccoon, the libido of the female is enhanced, the standing is uncertain, the hind legs are naturally separated, the tail is lifted, and the male is recalled. 3 Climb across ejaculation. After being strongly stimulated by the female's standing reaction, the male suddenly jumped over and climbed over the females. The forelimbs stretched their hips and their buttocks forced their way forward. They both stared in a daze, indicating that the ejaculation was completed and they automatically left. The mating process was about 7-12. minute.
The breeder should pay attention to observation and confirm that the female beaver should be separated from the single-parent rearing after being conceived; the female veterinarian should be pregnant after 16 to 20 days after being allocated. Pregnancy female veterinarians must maintain medium and superior nutritional status, not too fat and thin. In order to increase the rate of conception, male mate can be mated 2 or 3 times during the estrus period, or two male raccoons can mate with each other.
5. Pregnancy and fecundity At the beginning of pregnancy, the female is restless and restless. As the fetus develops and grows, the temperament becomes docile, likes quiet lying alone, behaving with caution, increased appetite, thickened nipples, and increased abdominal circumference. 5 days before the pre-production, provide clean hay and let the female be used as a nest. Before labor, the females lick their vulva, often finishing their litters, with little urine and frequent appetite. Most of the farrowing is at midnight, and care should be taken to keep the environment quiet and provide sufficient drinking water. Post-partum thirst or frightening can lead to the mother's “killing†behavior.
The female cubs produce 2 to 5 bees per birth, the majority of which are 3, and each cub is born weighing about 120 grams. 20-day-old up to 500 grams, about 40 days old about 750 grams, 50-60 days old beavers can be weaned, an average of about 1 kg body weight.
The female cub has a recessive estrus within 1 to 3 days after farrowing (ie, the female cub does not call when it is estrus). If it can seize this opportunity to breed (called blood allocation), the number of litters per year can be increased. If the blood is successfully allocated, the young bees should be culled from the ewes and fed artificially. Artificial nursing can use rice flour boiled into the juice, the amount of milk powder mix well, into the bottle so that the siberian sucking, feed 5 to 6 times a day, feed at 10 pm.
The breeding of civet cats
1. Sexual maturation and initial mating age Sexual maturation of females is generally between 10 and 12 months of age, and males are generally 18 to 22 months of age. Civet life is 15 years old, breeding age, female beet 1 to 10 years old, male raccoon 2 to 7 years old. Sooner or later, sexual maturity is related to birth time, feeding conditions and nutritional status. Juveniles produced before June, as long as the nutrition is good, can be sexually mature in 10 to 12 months of age, but after the June birth, even in the same nutritional conditions, generally to 19 to 22 months of sexual maturity.
