Visiting Irish county, see Scottish beef producer (8)
I believe the answer is:
galloway
'scottish beef producer' is the definition.
(type of cow)
'visiting irish county see' is the wordplay.
'visiting' means one lot of letters goes inside another.
'irish county' becomes 'galway' (I've seen this before).
'see' becomes 'lo' (archaic word meaning 'look!').
'galway' enclosing 'lo' is 'GALLOWAY'.
(Other definitions for galloway that I've seen before include "Scots breed of cattle" , "one belted" , "Scottish region" , "farm animal" , "Area of southwest Scotland" .)
