We opened our business 7 yrs. ago because my daughter had an auto-immune disease and her doctor said she needed to est grass finished beef. If she needed it I knew there would be others who needed it if not for what she had for something else like cancer or heart trouble. We added ALL NATURAL FOR THOSE THAT  have sensitivity issues.
Also we belong to an organization that is lobbying to lessen the use of antibiotics in animals because of the fear of it being in the meat and or the possible build up of antibiotic resistance by bacteria that could effect humans.
