Terms and Definitions

Cottonseed - Determined by the National Cottonseed Products Association (NCPA), Premium and Prime Feed grades contain, respectively; 1 to 2 percent foreign matter; 11 to 13 percent moisture; 38 to 34 percent crude protein and crude fat (combined totals for each); and 3 percent free fatty acids in the oil.

Delinted Cottonseed - There are two processes used for delinting cottonseed, mechanical and acid. Mechanically delinted is the most common form of delinted seed available in the feed trade. Mechanically delinted seed retains about 1-2% residual linters which usually appear on the ends of the seeds. Acid delinting is a process that completely removes all linters. This process is used for the production of planting seed. At certain times during the year, quantities of culled, or leftover planting seed, become available to the feed trade. Beware of such planting seed unless you can demonstrate that it does not contain chemical seed treatments.

Gossypol - A polyphenol ( C30 H30 O8 ) derived from the cottonseed plant and potentially irritating to gastrointestinal tract.

Lint - The ginned fibers from harvested cotton bolls.

Linters – The short fuzz left on the cottonseed after a mechanical delinting process.

NCPA – National Cottonseed Products Association – The NCPA is a national trade organization representing cottonseed crushers, dealers, brokers, chemists, and other allied interests within the industry:

Pima Cottonseed - This is the seed from pima varieties of cotton, also known as extra long staple (ELS) cotton. It represents a small percentage (about 2%) of U.S. cotton. Pima seed is genetically devoid of linters, the fuzz that covers the seed of upland varieties. Some nutritionists recommend that Pima seed be cracked prior to feeding.

Whole Cottonseed (WCS) – This term refers to fuzzy seed from upland varieties of cotton.
