Pole providing fruit as animal feed (4)
I believe the answer is:
mast
I believe this clue is a double definition.
'pole' is the first definition.
(I know that mast is a type of pole)
'fruit as animal feed' is the second definition.
(mast can mean fruit fed to pigs)
'providing' acts as a link.
(Other definitions for mast that I've seen before include "Pole to support a sail" , "One carries the sails of a ship" , "it rises on board a ship" , "Tall pole from which flag is flown" , "Vertical spar for supporting sails etc" .)
