Mealworm(Tenebrio molitor) was added to the feed to improve the health of dogs. As the amount of mealworm powder added to dog feed increased from 2.5 to 7.5%, the contents of crude protein, crude fat, crude fiber and crude ash increased. In the old dogs, creatinine and BUN related to nephropathy, triglyceride related to hypertension, calcium related to osteoporosis, globulin related to immunity, and ALT related to hepatic function were in the normal range. Particularly, ALT showed a tendency to increase overall, but the numerical increase tended to decrease as the amount of mealworm powder added. In the young dogs, all investigative items such as BUN and creatine were in the normal range and ALT tended to decrease at 2.5～5.0% treatment of mealworm. As a result, it was shown that adding 2.5～5.0% of mealworm powder to feed effectively improved the hepatic function of old and young dogs.
