THE DR. HESS PRODUCTS 
For more than 40 years, the products of Dr. Hess & Clark have been used with success by American farmers. These 
products are and always have been made with one high purpose in mind—to help produce better livestock and poultry, 
better beef, pork, milk and eggs. Year after year the Research Farm of Dr. Hess & Clark at Ashland, Ohio, tests and retests 
them in developing better methods to make market weight animals in fewer days, and to control parasites and diseases. 
That is why we recommend them to every stockman and poultry raiser.
