Direct bovine? (5)
I believe the answer is:
steer
This clue is a double definition.
'direct' is the first definition.
(I know that direct can be written as steer)
'bovine?' is the second definition.
(I know that steer is a type of Cattle)
(Other definitions for steer that I've seen before include "Reset so as to direct" , "Guide; bullock" , "Pilot a boat in desired direction" , "Guide, direct" , "Exercise control" .)
