Not knowing anything else about the context, I agree that Michael Harvey's comment is most probable:
Draft animals are those that pull loads or carry them: horses, oxen, buffalo, donkeys, etc. Swine are pigs. All of these animals can be eaten.
This is in opposition to Glorfindel's comment:
I'd guess 'draft' = 'draft beer' and 'swine' = 'porc' [sic].
Note: "porc" should be spelled "pork", in case you are new to English.
There are a couple reasons why draft most likely refers to draft animals here:
One does not feed on beer. Beer is a liquid, and liquids cannot be eaten.
The addition of swine in a way completes the draft because both (presumably) refer to animals, but pigs do not generally pull or carry loads and are for that reason not considered draft animals. It seems like the intention was to make sure that swine and other non-draft animals are not perceived to be excluded from the terrible fate that awaits horses, oxen, etc.
Also, pork can be synonymous with swine or refer more specifically to pig meat. I suppose either interpretation is acceptable here, as pork signifies the edible parts of swine.
Hope this helps!
