Korn- og Foderstof Kompagniet (KfK) was a Danish co-operative company in the feed-stuffs industry. Founded in Aarhus in 1896 by 12 merchants it grew through the early 20th century to become one of the largest Danish businesses trading in feed-stuffs and grain with branches in many Danish cities. It became one of the largest employers in Aarhus until the 2000s when the grain business was bought by a number of competitors, led by Dansk Landbrugs Grovvareselskab, and renamed Treka. The remainder of KfK was reformed into the company Biomar A/S, focused mainly on fish feed.
