Lemme wonder this, with the caveat that I’m feeling a bit behind the curve here.
So there is a rov that beheimos are not treifos. And that is why we can drink milk usually, and why we don’t need to check if an animal is a treifah in all of the possible ways before we eat it.
But do we ever say that the rov is a super strong 60-1 rov? And if it was, you’d expect some discourse on it with R’ Meir who doesn’t hold of rov except in super majority cases.
So forget that we know about the stomach stapling affecting 14%–how can you drink any milk anyway since there will likely be more than a shishim, if you mix it together with each other? And ??? ????, R’ Yehuda holds ??? ????? ????? ???? ?? ????, so would he hold that if you mix a bunch of cows milks together that you can’t drink it? And how do we mix meat from different cows together, if we only know that they are kosher by rov?
Don’t you kind of need to say like DY referenced above that the rov already paskened and we’re done. Unless you say something like that the milk is never separate since it all goes straight into the tank, but then won’t CY milk have the same problem because of the normal miut treifos?
