Stallion requiring endless research (4)

Ross

I believe the answer is:

stud

'stallion' is the definition.
(stud is a kind of stallion)

'endless research' is the wordplay.
'endless' means to remove the last letter.
'research' becomes 'study'.
'study' with its last letter taken away is 'STUD'.

'requiring' acts as a link.

(Other definitions for stud that I've seen before include "Macho - stable - boss" , "Small piece of jewellery" , "Decoration" , "Horse-breeding establishment; jewellery item" , "Specified arrangement" .)

I've seen this clue in The Telegraph.
