School shall get animal feed (5)
I believe the answer is:
swill
'animal feed' is the definition.
(I know that swill is a type of fodder)
'school shall' is the wordplay.
'school' becomes 'S'.
'shall' becomes 'will' (synonyms).
's'+'will'='SWILL'
'get' acts as a link.
(Other definitions for swill that I've seen before include "drink heavily" , "Guzzle" , "Wash" , "Rinse - pig food" , "Pigs' food" .)
