Numbers I find in a Google aren't really mine.

Howevber, those numbers were the percentage who get DA. Of those,
those healthy enough for surgery are operated on and thereby are
tereifos. The farming web site I found didn't give statistics for
other forms of tereifos. It merely established the likelihood that
more than 1:60 are tereifos because of DA surgery. If 1:60 is a
meaningful measure,

However, I see this case not as one of straight bitul, but of the
machloqes about whether the odds of the components of a ta'aroves add
back together. If so, then according to the Rash, the mixed milk would
be decided by the combined odds of each of the cows involved. But even
according to the Rash would be rov, not bitul beshishim.

And then add to that the question of whether the Rash would even be
machmir by a ruba deleisa leqaman. The case of the ta'aroves was where
the set including the cheilev was reconstituted and eaten. By a leisa
leqaman, there is no such set.

Tir'u baTov!
