cotton seed
Cotton seeds are the seeds of the cotton plant. Cotton seeds are ovoid, 3.5-10 mm long. They are densely covered with white or rusty, long and woolly hairs, called the lint, which is the main product used to make cotton textiles, and shorter hairs (linters). Commercially available cotton seeds are usually the by-product of the production of cotton fibre by a cotton gin, which separates the lint from the seeds.
Cottonseed cake is the by-product of oil extraction from cotton seeds. As a protein-rich feed, cottonseed cake is a common source of protein for ruminants, notably in cotton-producing areas such as India, China and the USA, where it is used as a partial substitute for soybean meal.
