I believe the answer is:

fishmeal

I'm a little stuck... Click here to teach me more about this clue!

'animal feed' is the definition.
'fishmeal' can be an answer for 'feed' (I've seen this before). I'm not sure about the 'animal' bit.

'angle this writer primarily adopted lacking' is the wordplay.
'angle' becomes 'fish' (synonyms).
'this writer' becomes 'me' (the person who wrote the clues).
'primarily' suggests taking the first letters.
The first letters of 'adopted lacking' is 'al'.
'fish'+'me'+'al'='FISHMEAL'

Can you help me to learn more?

(Other definitions for fishmeal that I've seen before include "fertiliser" , "feed" , "Fertilizer possibly" .)
