This document summarizes different types of corn and their uses in poultry feed. It discusses yellow corn, which contains high levels of xanthophyll pigments that give egg yolks and chicken skin their yellow color. White corn has similar properties but lower protein content. High-lysine corn was developed to have 50% higher lysine content. Corn meal, made from grinding whole corn kernels, is a major ingredient in poultry feed and contains around 8.8% protein and 3.8% fat. The document also provides details on the composition of a corn kernel.

Definitions of Corn Grain Milling ‫اﻟﺬرة‬ ‫ﺣﺒﻮب‬ ‫ﺗﺼﻨﯿﻊ‬ ‫ﻣﻔﺎھﯿﻢ‬
Dry-milled: the process by which the entire corn kernel is ground into a meal and then
fermented into alcohol.
Wet-milled: steeped in water with or without sulfur dioxide to soften the kernel in order to
facilitate the separation of the various component parts.
Corn Distillers Dried Solubles: obtained after the removal of ethyl alcohol by distillation
from the yeast fermentation of a grain mixture by condensing the thin stillage fraction and
drying it by methods employed in the grain distilling industry.
Corn Distillers Dried Grains: obtained after the removal of ethyl alcohol by distillation from
the yeast fermentation of agrain or grain mixture by separating the resultant coarse grain
faction of the whole stillage and drying it by methods employed in the grain distilling
industry.
Corn Distillers Dried Grains with Solubles (DDGS): product obtained after the removal of
ethyl alcohol by distillation from the yeast fermentation of a grain or a grain mixture by

condensing and drying of the solids of the resultant whole stillage by methods employed in
the grain distilling industry.
Distillers Wet Grains (WDG): product obtained after the removal of ethyl alcohol by
distillation from the yeast fermentation of a grain mixture. The guaranteed analysis shall
include the maximum moisture.
Corn Gluten Feed (DCGF = dried ;WCGF = wet): part of the commercial shelled corn that
remains after the extraction of the larger portion of the starch, gluten, and germ by the
processes employed in the wet milling manufacture of corn starch or syrup. It may or may not
contain one or more of the following: fermented corn extractives, corn germ meal.
Corn Gluten Meal: dried residue from corn after the removal of the larger part of the starch
and germ, and the separation of the bran by the process employed in the wet milling
manufacture of corn starch or syrup, or by enzymatic treatment of the endosperm. It may
contain fermented corn extractives and/or corn germ meal.
Steep-extracting: soaked in water or other liquid (as in the wet milling of corn) to remove
soluble materials.
Steepwater: water containing soluble materials extracted by steep-extraction
Germ: the embryo found in grains and frequently separated from the bran and starch
endosperm during milling.
Stillage: the mash from fermentation of grains after removal of alcohol by distillation.
Distillation Solubles: stillage filtrate
