Sam2 – thank you.
If someone mixes the pig’s milk with cow’s (a healthy cow), and we have this mixture 49% pig milk, 51% cow’s milk, do we, or do we not, go by the majority and say the mixture is milchig? which would be a problem if that person should eat kosher beef with that. Better eat it with pork chops. Is a mixture milchig only if it is kosher?
If instead we shecht the cow and there’s a pig inside which remains alive, the pig is forbidden derabanan but (if he has the simanim of the pig) its milk I think would be issur d’oraita? is that correct?
Shmoolik I do not think it is chadash, as it is discussed at length what to do if an animal without simanim is born from a kosher animal.
