The number of oocysts per gram of feces was examined to observe the change of egg sac quantity of coccidiosis. The results showed that coccidia oocysts could be detected in the feces of rabbits at each age stage in A and B rabbit farm, while hardly detected in C rabbit farm. Coccidiosis is a common parasitic disease in rabbits, but not in every rabbit farm. Prevention should be given priority to, while treatment should be supplemented.
