A little lower if put in here perhaps (6)
I believe the answer is:
heifer
'a little lower' is the definition.
(I've seen this before)
'if put in here perhaps' is the wordplay.
'put in' is an insertion indicator (back).
'perhaps' indicates anagramming the letters.
'here' with letters rearranged gives 'heer'.
'if' put within 'heer' is 'HEIFER'.
(Other definitions for heifer that I've seen before include "Cow that has borne one or no calves" , "Female bovine that has not given birth" , "a little lower" , "Young cow which has not yet given birth" , "part of stock" .)
