Application for Approval
of Yorkshire Boar(s)
For Use In Artificial Insemination
The American Yorkshire Club, Inc., in order to ensure and preserve the purity of Yorkshire swine resulting from the artificial insemination of sows by a boar not owned by the owner of the sow at the time of breeding, requires that such boar must be test mated successfully to one Duroc, Hampshire or Duroc/Hampshire sow or two dark cross sows, that there be at least 8 live pigs born; and that none of the pigs born in any of the litters have any solid color. "Solid color" means hair color other than white or roan. No test breeding to Spots or any white breed will be accepted. After the test matings, the affidavit attached hereto must be filed with the American Yorkshire Club, Inc., by the owner of the boar. No pigs will be registered from a litter resulting from artificial insemination by a boar not owned by the owner of the sow on the date of breeding, if this affidavit is not on file with the American Yorkshire Club, Inc. The affidavit must be filled out completely, signed by the registered owner of the boar and returned to the National Swine Registry. All imported Yorkshire (boars, gilts and/or sows) must complete the appropriate test mating requirements and stress requirements set by the AYC Board of Directors.
