Used to manage cattle and horses, primarily (5)
I believe the answer is:
ranch
'used to manage cattle' is the definition.
I can't judge whether this definition defines the answer.
'and horses primarily' is the wordplay.
I cannot quite understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
The remaining letters 'rach' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ranch that I've seen before include "Hacienda" , "A large cattle-breeding farm" , "Large tract of land for raising livestock" , "Run a cattle farm" , "Cattle estate" .)
