Gratitude Descendants’ Sales Suspended

February 17, 2010 04:30 AM
 
PLAIN CITY, Ohio, Feb. 17, 2010 — Select Sires Inc., and members of the American Jersey Cattle Association (AJCA) have been officially notified by the AJCA that Oomsdale Gordo Goldie Gratitude (111224922) is not of pure Jersey descent.
 
As a result of this announcement, Select Sires has chosen to temporarily suspend sales of the following descendants of Gratitude following the guidance of Select Sires' Jersey Sire Committee: 7JE1013 Oomsdale Jac Casey COWELL-ET and 7JE1031 Cal-Mart Dale SPIKE 3951-ET. Additional descendants that were distributed and sampled include, 7JE768 OomsDALE Jace Gratit Garden-ET, 7JE779 Oomsdale Morgan Gratitude MIKE, 7JE884 Bohnerts Garden AUNDRY, and 7JE955 Oomsdale Brazo Grat GOOFEY-ET.       
 
Select Sires staff is cooperating fully with the AJCA and AIPL geneticists who have begun the systematic process to discover, to the fullest possible extent, the percentage and source of non-Jersey DNA in the genomics of these animals. The investigation has centered on the dam, Oomsdale Gordo Goldie Gratitude because the identity and Jersey breed-specific SNP profiles of the sires of the above-listed progeny are not in question.
           
The cow, Gratitude, was DNA-typed by ImmGen Inc. in 2002 in accordance with AJCA rules governing registration of embryo transfer (ET) progeny. Adopted in 2002 and replacing blood typing, DNA-typing is the AJCA's official method of parentage qualification. Her dam, Oomsdale Alf Gloria Goldie, and maternal grandam, Oomsdale Herm Groovy Gloria, had been previously blood typed as ET donor dams, and were DNA-typed in 2002 in conjunction with parentage verification request for Gratitude. The sire of record for Gratitude, Bold D Gem Gordo, was not alive and had not been previously blood typed. On the basis of its tests and available information, ImmGen Inc. reported to the AJCA and the breeder, Michael A. Ooms, that the DNA-types of Gratitude, her dam Goldie and the grandam Gloria were consistent with the AJCA recorded parentage.
           
The discovery that the ancestry of Gratitude was not pure Jersey was made using genomic SNP technology. This new technology was implemented by the AJCA for Jersey genomic evaluations in 2009.
           
Gratitude is dead and not available for genotyping. However, AIPL geneticists have examined the DNA of the 15 genomically tested progeny in addition to DNA obtained from the cow's maternal grandam, Oomsdale Herm Groovy Gloria, and Oomsdale Grand-ET, a maternal brother of Gratitude. Their conclusions are:
1.      Oomsdale Alf Gloria Goldie has been confirmed as the dam of Oomsdale Gordo Goldie Gratitude.
2.      No conflicts were found in the breed check of the genotypes for Oomsdale Herm Groovy Gloria and Oomsdale Grant-ET.
3.      Based on the Holstein DNA identified in the genomes of the 15 progeny, the Holstein inheritance of Gratitude has been imputed as 22.3 percent and is paternal in source. The most likely source is a red-carrier Holstein bull.
           
AIPL geneticists are now examining available bull genotypes in an effort to identify the source.
 
On March 13 and 14, 2010, the AJCA Board of Directors will meet to determine the course of action that is in the best interest of the Jersey breed and its members. Further direction will be provided by the AJCA for this issue at this time.
           
Select Sires' Jersey Sire Committee met today, February 17, 2010, to gain further knowledge of this circumstance and determined that due to these findings Select Sires requests that the federation temporarily suspend the sale of all bulls related to this family until the AJCA board of directors reaches a permanent decision.
           
Select Sires' solid history of working with the AJCA's board of directors and staff gives us strong confidence that the AJCA will handle this difficult situation in a progressive manner that will benefit the Jersey breed and the dairy industry.
