Muskrat is sexually mature at 100 days of age, that is, into the puberty. However, the age of sexual maturation in wild mice differs depending on factors such as the season and nutritional conditions. The domestic rat can breed after 5 months of age under good living and nutritional conditions. The length of the breeding period of the mole is related to climate, nutrition and living environment. In southern China such as Zhejiang, Jiangsu, Hubei, Sichuan, and Guizhou, due to the warm climate, luxuriant aquatic plants and long breeding season, they are generally not available from February to October. In areas such as Hebei and Northeast China, due to the cooler climate and slower growth of grasses and other green feeds, the breeding season is short. Generally, from mid-April to the end of August, captive mice are mostly estrus in late March and will be produced in early September. After the last litter.
Muskrat is a seasonal estrus animal. Male rats are in estrus throughout the breeding season; female rats are in periodic heat, their estrus cycle is 12 to 14 days, estrus lasts 2 to 4 days, and intercourse is 10 days.
The artificial breeding method of the Mole is roughly one male and one male and one male and two female. A male-female method, usually after sex identification, selection, matching, and estrus, is used to feed male and female rats in the same enclosure until the end of the breeding season. If it is found that there is still no maternal pregnancy after more than 30 days, the rats should be replaced in time and the matings must be re-matched.
One male and one female mating method, that is, one male rat and several female rats are always kept in a cage and allowed to breed freely. Although this law is simple and convenient, but the cage is larger, and there is competition for food, the effect is not very good. In the mating, the male rats actively take the initiative to chase each other, play, and climb. After 1 to 3 hours, they eventually reached the market in the pool, and they rarely reached the stadium or nest. Most of the matings are concentrated at about 4 o'clock in the morning or 14 to 21 o'clock in the afternoon. Each mating time is about half a minute to one minute. Muskrat gestation 25 to 30 days, in the late pregnancy, the abdomen showed significant sagging. The maternal calving is usually carried out in the litter chamber. The male rats are sent to the foxock for 1 to 2 days before the childbirth to send grass and block the door until the maternal is 7 to 8 days after farrowing. During this period, the male and female rats frequently send and receive foals for the dams, close the door, and keep guards outside the nest.
The mother began to whisper again 3 to 7 days (or 14 to 16 days) postpartum and asked for mating. The average number of litters in the maternal rats was 7.4, and 5.7 in the early mother rats. The number of male rats in the neonatal rats was approximately 58%. The newborn baby has a pink skin, and the baby's hair is short and grey, weighing 20 to 22 grams. Eyes closed, ears only a small tumor-like protrusions. At the age of 3 days, the incisors grow out. At the age of 7 days, the incisors show their lips. When they are 10 days old, they work out their coats. They open their eyes 10 to 12 days of age, and 18 to 20 days old can eat young grass and start to walk out of the room and into the water. Swimming, weighing more than 220 grams at 30 days of age.
