Rapeseed is the third-largest source of the vegetable oil and second-largest source of the protein meal in the world. Processing of rapeseed for oil production produces rapeseed meal as a byproduct.
The byproduct is a high-protein animal feed, competitive to soybean. The rapeseed meal is employed mostly in cattle feeding, as well it can be used for pigs and poultry. Rapeseed oil is one of the oldest known vegetable oils, but historically was used in limited quantities due to high levels of erucic acid, which is damaging to cardiac muscle of animals, and glucosinolates, which made it less nutritious in animal feed.
