Corn steep liquor is a high-protein, high-energy feed ingredient made from the soluble parts of the corn kernel through a steeping process. It is a viscous liquid mixture consisting entirely of water-soluble components of corn steeped in water. CSL is a kind of byproduct produced in the processing course of corn starch. It is widely used in liquid form in pig and ruminant feeds and as a binding or pelleting agent in other feeds. These Corn Steep Liquors are a premium additive to the cattle feed. Owing to the high nutritive content (rich in vitamins, lattice acid and proteins) of the Corn Steep Liquor, it is valuable for Enzyme, Animal Feed and Pharmaceutical industries.
