All procedures associated with the pre-entry qualifying procedures performed
on the farm of origin are to be performed by a veterinarian authorized to
perform these functions as an accredited veterinarian.

15.7.1.1 The herd of origin must be inspected and found free from clinical
evidence of infectious disease and insofar as can be determined, from
history of infectious disease during the preceding 60 days.

15.7.1.2 The donor animals or teasers should remain in isolation at the
premises of origin and must not be exposed to any infection to which they
are susceptible from the date of pre-entry health testing until entry into
the designated section of the A.I. Center.

scrapie, pulmonary adenomatosis, caseous lymphadenitis, bluetongue and other
communicable disease. To the best of the veterinarians knowledge and belief
pulmonary adenomatosis has not been diagnosed in the flock of origin during
the previous five years and that the scrapie has not been diagnosed in the
flock of origin, or in the flock in which the donor ram was born, if
different from the flock of origin, during the previous six years and that
the donor ram is not the progeny of a sire or dam that was affected by
scrapie and the animal has been subjected to the following tests with
negative results within 60 days prior to entry into the isolation section of
the A.I. Center.
