Wheat germ et germ oil meal

IMPORTANT INFORMATION: This datasheet is pending revision and updating; its contents are currently derived from FAO's Animal Feed Resources Information System (1991-2002) and from Bo Göhl's Tropical Feeds (1976-1982).

Datasheet

Description
Click on the "Nutritional aspects" tab for recommendations for ruminants, pigs, poultry, rabbits, horses, fish and crustaceans
Common names 

Wheat germ, wheat germ meal, wheat germ oil meal, wheat germ oil cake

Species 

Triticum aestivum L. ; Triticum spp. [Poaceae]

Feed categories 
Related feed(s) 
Description 

Wheat germ is a valuable feed rich in digestible protein and low in fibre, and contains about 10% oil that is rich in vitamin E.
Sometimes the oil is extracted, yielding wheat-germ oil meal. Usually the wheat germ is mixed with the shorts to give a product called middlings

Nutritional aspects
Potential constraints 

Wheat germs kept for a few days are likely to become rancid.
