Reply To: Chalav Stam? no such a thing

I am not sure what your other quote from the Rambam here was doing. Since he Paskens (based on several reasons from the Gemara) that a Treifah won’t live and a Treifah can’t have kids, we can use that to verify whether or not that animal is a Treifah. However, he explicitly states that we only do this if an animal is a Safek if it will be a Treifah. If we know for sure that it is a Treifah (we saw the needle go through and come out the other side) then of course these signs won’t help.
