A Northern Irish lady brings in large man for stock control (6,9)
I believe the answer is:
animal husbandry
'stock control' is the definition.
(breeding animals - stock means farm animals)
'a northern irish lady brings in large man' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
'northern' could be 'n' (abbreviation e.g. N. Ireland) and 'n' is found in the answer.
'large' could be 'l' (eg in clothes sizes) and 'l' is found within the answer.
'man' could be 'ad' and 'ad' is present in the leftover letters.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
(Another definition for animal husbandry that I've seen is " Farming".)
