Pig keeper: wind here's terrible! (9)
I believe the answer is:
swineherd
'pig keeper' is the definition.
(someone who keeps pigs)
'wind here's terrible' is the wordplay.
'terrible' indicates an anagram.
'wind'+'heres'='windheres'
'windheres' anagrammed gives 'SWINEHERD'.
(Other definitions for swineherd that I've seen before include "Tender of pigs" , "Tamworth's keeper" , "Farmhand" , "I work on farm" , "Pig tender" .)
