Stored fodder (6)
I believe the answer is:
silage
'stored fodder' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for silage that I've seen before include "Fermented feeding stuff for cattle" , "Animal feed" , "Animal fodder harvested while green and partially fermented" , "Form of fodder" , "Animal foodstuff" .)
