When the sire or dam was owned by someone other than the OWNER at the time of mating, parentage must be confirmed by a Breeding Certificate or Ram Lease form. The person selling a bred ewe or leasing a ram should complete the appropriate sections below and pass to the new ewe owner or ram lessee. This completed form should be submitted to the registry when registering lambs from this mating. A Breeding Certificate records exposure up to 157 days from the last day of mating. Lambs born during this period would be eligible for registration. Breeding Certificates and Ram Leases must bear the original signature of the person issuing the documents.
