Huddersfield displays dairy production equipment (5)
I believe the answer is:
udder
'dairy production equipment' is the definition.
'huddersfield displays' is the wordplay.
'displays' indicates a hidden word.
'UDDER' is hidden within 'huddersfield'.
(Other definitions for udder that I've seen before include "Steer with this" , "Teat of a cow" , "Cow's milk source" , "Part of beastly female" , "Mammary gland of cow" .)
