A system and method for converting gin trash to a pelletized feed or supplemental feed for ruminant animals. Such a system or method may include removal of a substantial portion of the immature cotton fiber content from the gin trash in order to ensure the consistency of the pellets produced. The processed gin trash may be mixed with cottonseed meal and corn. The amount of cottonseed meal added may be selected such that the pellets are digestible by ruminant animals, but not non-ruminant animals. The amount of cottonseed meal added may be further selected such that the gossypol content of the pellets results in adverse health effects to non-ruminant animals if ingested.
