Sheep consume loudly (4)
I believe the answer is:
ewes
'sheep' is the definition.
(a ewe is a female sheep)
'consume loudly' is the wordplay.
'consume' becomes 'use' (use can mean to consume or get through).
'loudly' shows a homophone (sound like) (when spoken - not silently).
'use' sounds like 'EWES'.
(Other definitions for ewes that I've seen before include "wool producers" , "farm animals" , "Adult sheep" , "Female sheep" , "Females in the flock" .)
