Midwest Ag Supplements LLC

Located in Marshall, MN, Midwest Ag Supplements began in 2002 when four individuals began their dream of producing high-quality livestock supplements by adding value to many by-product streams coming from area food and biofuel processing plants.   These individuals brought a wealth of practical experience not only in livestock nutrition and production but also in bio-fuel and corn sweetener co-products and marketing. By sourcing many of the ingredients in a close proximity to Marshall, Midwest Ag Supplements LLC can provide area dairies and cattle operations with top-tier products at affordable prices.
