Litter of pigs (6)
I believe the answer is:
farrow
'litter of pigs' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for farrow that I've seen before include "Produce piglets" , "Litter - very much on bank?" , "Actress" , "Little piggies" , "Give birth to piglets" .)
