Indeed they do, but what has that got to do with rov?  Each cow has
its own chezkat kashrut, until some event occurs to destroy that
chazakah; but that has nothing to do with the status of the majority
of cows.  Neither you nor I nor RHS know the status of the majority of
dairy cows, either in aggregate or at any particular age.  All we know
is that by the end of their working life there appears to be a large
majority of treifos, *if* the samples examined are representative and
statistically significant; at what stage these treifos developed, who
can say?
