Interpretive Summary: Cotton Gin Waste (CGW) presents a substantial problem for cotton ginners because about 3 million tons are produced annually. One method to utilize CGW is to feed it to cattle, however, problems exist because of potential pesticide contamination. This study evaluated the pesticide reduction potential of extruding CGW with various quantities of cottonseed. Results suggested that some pesticides such as Dropp were significantly reduced while others were not. Additional research is required to develop technology to render the potential pesticide residue in CGW harmless.

Technical Abstract: 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.
