How to identify pregnancy in cultured bamboo rats

First, look at the nipple pregnant bamboo mouse from the nipple, the nipple is red, the hair on both sides of the nipple turns out, the pregnant bamboo mouse belly is obviously bigger than the average mouse belly, you can feel it with your hands.

Second, it is shown that after pregnancy, bamboo rats will get all the hay into a corner and form a nest to wait for delivery. 1. Male and female mice will be examined 5-7 days after mating in a cage. For example, the hair around the female rat's nipple is turned out, and the nipple becomes larger and darker, often pink, and has become pregnant. 2. According to the time of gregarious feeding, it can be estimated that if the female rats eat more food than usual after one month of male and female cages, the width of one finger in the abdomen increases, and when they are full, they can be judged that the female rats are pregnant. 3. One month after mating, lift the mother rat upside down, if the abdominal groove on the inside of the hind legs is full, it is pregnant; if you lift the full mother rat upside down, you can only see abdominal distension, but the groin on the inside of the hind leg is not full, then it is not pregnant. 4. In addition, in the course of daily feeding, you can probably see the mating of male and female mice once or more times, or after lifting the female mice upside down, you can see that there is a white sticky substance (male mouse semen) in the genitalia. These conditions can give you a reference for judging the pregnancy of female mice. 5. Beginners should do a lot of research and careful observation in the process of feeding. Only in this way can the technology continue to improve and lay a good foundation for high yield.
