The three transitions are the transition of feed, the transition of environment and the transition of feeding procedures. The feed transition is to feed the original feed as much as possible within 2 weeks after weaning and gradually transition to the new feed. In order to better prevent diarrhea, it is best to add microecological preparations in the feed; when the rabbits are weaned, the amount of feed should be controlled at eight fullness. The environmental transition mainly means that the rabbit's living environment must remain relatively stable, including the original cage and the original nest. Especially the rabbits in the original nest must be kept together. The transition of feeding procedures is based on the original feeding system, and the keeping personnel are relatively stable.
