Description 
A flower cultivated mainly in East Africa for its content of pyrethrins, which are used in insecticides. Pyrethrum marc is the waste product of pyrethrum flowers that have been ground and extracted with petroleum ether.
Nutritional aspects
Potential constraints 
Before the marc can be used as feed it has to be steamed to remove the residual solvents and destroy the remaining pyrethrins, which are poisonous to stock.
Ruminants 
The marc is readily accepted by stock and has a high feed value; however, it should not be used for more than 50% of the roughage portion as it depresses productivity. It does not produce off-flavour in milk.
