1. Rabbits with diarrhea are more likely to have diarrhea than adult rabbits, especially the incidence rate of diarrhea in newborn rabbits is very high. First of all, consider the quality of the feed. If the rabbit herd shows a large number of symptoms of diarrhea, especially after just changing the feed, it is necessary to consider whether the feed has mold or if the rabbit cannot adapt. Secondly, consider the amount of feed to be fed, especially for weaned rabbits, which are often stretched out. Considering that rabbits are infected with Escherichia coli, Salmonella, or Clostridium welchii, bacterial diarrhea generally occurs after ordinary diarrhea.

Outbreaks often occur in early spring, and once they occur, they quickly spread to the entire population, with a mortality rate of over 95%. The rabbit with acute disease suddenly fell to the ground, screamed and cramped, and died.
