Reply To: Chalav Stam? no such a thing

I don’t recall if it was R’ Reisman or R’ Belsky, but one of them observed the cows that underwent the procedure. Very few of them died within a year (I don’t say none, because they could die from other causes). The death rate was no higher from these cows than the cows that didn’t have the procedure. Because a treifah means it will die within a year, he concluded that the procedure does not make the animal a treifah.
