'a pig?' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'doctor parries bishop a bit of' is the wordplay.
'doctor' indicates an anagram.
'a bit of' suggests taking the first letters.
The initial letter of 'bishop' is 'b'.
'parries' with letters rearranged gives 'spareri'.
'spareri'+'b'='SPARE-RIB'
