Processing Cottonseed and Gin Waste Together to Produce a Livestock Feed

J. A. Thomasson, W. S. Anthony, J. R. Williford, W. H. Johnson, S. R. Gregory, M. C. Calhoun and R. L. Stewart


Whole cottonseed and cotton gin waste (CGW) were mixed together and then heated and compressed to produce a material suitable as a livestock feed. The product was in the form of chips that would be easy to handle with feed handling equipment. The nutritional value of the product was good, free gossypol content was greatly reduced during the process, and Methomyl and Dropp residues were reduced while those of other chemicals were not. The process required only two machines: a ribbon mixer and an expander cooker. Seed to CGW mix ratios of 1:1 up to 9:1 worked well with this process, but attempts with less seed than CGW resulted in an unacceptable product.
