Wheat

Wheat is a cereal grain primarily grown for human food products, however a sizable amount is used in the feed industry. It contains slightly more protein and lysine but a similar energy value to that of corn. The feeding value performs slightly better than corn when fed in limited amounts. Avoid over processing because wheat has a tendency to flour and form small fine particles. Over processing will also reduce palatability and lead to consumption and handling problems.

While wheat improves pellet quality, the nonstarch polysaccharide (NSP) content may limit inclusion rate in poultry diets unless using enzymes.

 

 
Wheat grade requirement
Hard Red Spring:
Hard, brownish, high protein wheat used for bread and hard baked goods. Bread Flour and high gluten flours are commonly made from hard red spring wheat. It is primarily traded at the Minneapolis Grain Exchange.
Hard Red Winter:
Hard, brownish, mellow high protein wheat used for bread, hard baked goods and as an adjunct in other flours to increase protein in pastry flour for pie crusts. Some brands of unbleached all-purpose flours are commonly made from hard red winter wheat alone. It is primarily traded by the Kansas City Board of Trade.
Hard White:
Hard, light colored, opaque, chalky, medium protein wheat planted in dry, temperate areas. Used for bread and brewing.
Soft White:
Soft, light colored, very low protein wheat grown in temperate moist areas. Used for pie crusts and pastry. Pastry flour, for example, is sometimes made from soft white winter wheat.
Soft Red Winter:
Soft, low protein wheat used for cakes, pie crusts, biscuits, and muffins. Cake flour, pastry flour, and some self-rising flours with baking powder and salt added, for example, are made from soft red winter wheat. It is primarily traded by the Chicago Board of Trade.
Durum, very hard, translucent, light colored grain used to make semolina flour for pasta.
