Bunch of bovines (4)
I believe the answer is:
herd
'bunch of bovines' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for herd that I've seen before include "Group of cows, elephants etc" , "Drive" , "Animal group" , "Crowd of cattle" , "Group of people behaving like sheep?" .)
