Debbie:

       My recall, and it was many years ago, was that it takes all of a month
for ALL the bovine protien to clear.

       I would encourage mom ( or you) to contact Maryelle Vomlanthen... She
is online and sometimes joins in her so you might find her e-mail in the
files... otherwise she teaches at the University of Ark. I believe she is in
Little Rock.
