How to tell whether a bamboo rat is pregnant during breeding

1. Look at the nipples. In a pregnant bamboo rat, the nipples look red, the fur on both sides of the nipples turns outward, and the belly of a pregnant bamboo rat is noticeably larger than that of an ordinary rat; you can feel it by touching with your hand.

2. Look at the behavior. After becoming pregnant, the bamboo rat will gather all the dry grass from around into one corner, forming a nest for giving birth. 1. Check 5-7 days after the male and female rats are put together in the same cage to mate. If the fur around the female rat's nipples turns outward, and the nipples are exposed, enlarged and darker in color, often pink, she is already pregnant. 2. Estimate according to the time the male and female are kept together as a group. If, 1 month after the male and female are caged together, the female rat eats more than usual, the sides of her abdomen enlarge by one finger width, and she sleeps as soon as she is full, it can be judged that the female rat is already pregnant. 3. After 1 month of mating, lift the female rat up upside down. If the groin on the inner side of both hind legs is full and swollen, she is pregnant; if you lift a female rat that has just eaten her fill upside down and see only abdominal swelling while the groin on the inner side of the hind legs is not full and swollen, then she is not pregnant. 4. In addition, during daily feeding, you can generally see the male and female rats mating once or twice or more, or after lifting the female rat upside down you may see a white sticky substance in the reproductive tract (male rat semen). These conditions can all serve as references for judging whether the female rat is pregnant. 5. Beginners should study more and observe carefully during the feeding process. Only in this way will their skills continue to improve and lay a good foundation for a high birth rate.
