Brand bearers (6)
I believe the answer is:
cattle
'brand bearers' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cattle that I've seen before include "Ruminant animals with horns and cloven feet" , "Oxen, cows, bulls etc" , "feature of 21/23 [NATIVITY SCENE]" , "Bovine creatures" , "Where it naturally lies (Latin)" .)
