Pigs' food and drink (5)
I believe the answer is:
swill
I believe this is a double definition.
'pigs' food' is the first definition.
(I've seen this before)
'drink' is the second definition.
(swilling is a kind of drinking)
'and' acts as a link.
(Other definitions for swill that I've seen before include "drink heavily" , "Wet pig feed" , "Wash" , "Rinse - pig food" , "Waste food left in wills" .)
