Effects of pelleting and sterilization of diet on 2 strains of rabbit coccidia.

Both autoclaving and irradiation at levels currently used for other laboratory animal diets appear to be satisfactory for the elimination of 2 of the most robust and pathogenic species of rabbit coccidia. Pelleting by the usual methods, even at 68 degrees C, was found to be unsatisfactory in eliminating all oocysts from heavily infected diet.
