Brookside Agra

In 1985, Donald and Margaret Riesenberg founded Brookside Agra in their home in Highland, IL. With five generations of farming and feed manufacturing expertise, Brookside Agra is still family owned and operated and boasts an impressive lineup of industry experts who continue to research and develop new products. Through the years, Brookside Agra’s priority has remained the same — to develop all-natural products that successfully meet customer needs and requests, using in-vivo and in-vitro testing methods as its foundation for product development.
