What sort of item? food, horn etc
You could make it Milkable (see the cow or muffalo for a template)
Then make a custom "milk" which is the item you want?
Or add a bodypart to it which you get on butchering (see thrumbo for a template) You will need to make the ThingDef also unless it is a vanilla item you are wanting.
