Datasheet

Description
Click on the "Nutritional aspects" tab for recommendations for ruminants, pigs, poultry, rabbits, horses, fish and crustaceans
Common names 
Abyssinian kale, colewort, crambe, chou d'Abyssinie, crambe d'Abyssinie, krambe, Abyssinian kale, Abyssinian cabbage

Description 
Erect annual herb 10-90 cm high with large pinnately lobed leaves. As it matures, the leaves drop and the seed pods and stems turn tan. The pods are harvested for the extraction of oil from the seeds.
Nutritional aspects
Potential constraints 
The residual seed meal, though high in protein (40% in decorticated meal and about 30% in other meal), contains glucosinolates which make it unpalatable and limit its use for animal feed. It can be made palatable by treatment with ammonia or sodium carbonate, to neutralize the undesirable components, or by heat treatment.
Ruminants 
The oilcake can be included up to 50% in supplements for ruminants.
