Rabbits live together with rabbit, at the age of a little more than a month, almost all die and there are no obvious symptoms of the disease. For example, in the evening everything was fine, and in the morning you find the body of a rabbit. Everything gradually dies out, at best, there is only one rabbit left. (Eugene)
What is the reason and how to solve the problem?
Eugene, hello. Despite the fact that there are no obvious signs of the disease, in this case there are two ways to solve the problem. First, the rabbit itself may be to blame. You describe the situation in the past tense, that is, does it repeat from you or for the first time, did you not understand?
If such a situation is repeated from time to time and there are no other signs of rabbit disease, then most likely it is the female herself who chokes them. In this case, baby rabbits should be taken for breastfeeding or enclosed to another lactating mother. This is the only way to solve the problem.
The next moment is an infection or a virus. It is no secret that babies are very vulnerable, especially in the first months of life. It is necessary to make vaccinations and prophylactic drinking with vitamins, antibiotics. The infection may be in the inventory and in the cage. Therefore, before each cell and transplant, cells must be fired or treated with special disinfectants.
Also the source of the virus is often the female. In this case, the visible symptoms of her may not be, but she will act as a carrier. Naturally, along with the milk, the infection will penetrate into the weak and susceptible body of the baby. It is necessary to do the analysis and prevention of the rabbit.
As you can see, the reasons are serious, but I am more inclined to the first case. If the rabbit dies for no apparent reason or symptoms, then the rabbit is often to blame. Try to drop babies and observe their further state.
