Intend to keep a large brood, not just one litter (10)

I believe the answer is:

palanquins

'not just one litter' is the definition.
(a litter is a type of transport eg a palanquin)

'intend to keep a large brood' is the wordplay.
'intend' becomes 'plan' (planning is a kind of intending).
'to keep' indicates putting letters inside.
'large brood' becomes 'quins' (short for quintuplets).
'plan' placed around 'a' is 'palan'.
'palan'+'quins'='PALANQUINS'

I've seen this clue in The Times.
