The second was to compare the effects of the different floating liquids on the destruction of rabbit coccidia oocysts. The results indicated that magnesium sulfate solution showed the lowest rate of coccidia oocyst destruction at 20 min; saturated salt water had the greatest rate of destruction. The destruction increased with time; in the saturated salt water and urea solution damage or deformation of a few coccidia oocysts at were observed 60 min.
