Some stock book by Latin poet (5)

I believe the answer is:

bovid

'some stock' is the definition.
(a farmer's stock includes bovine animals or cows)

'book by latin poet' is the wordplay.
'book' becomes 'b' (abbreviation for book).
'by' means one lot of letters go next to another.
'latin poet' becomes 'ovid' (Roman poet).
'b'+'ovid'='BOVID'

I've seen this clue in The Times.
