DNA REQUIREMENTS

DNA testing in beef cattle is commonly used for:

Parentage Determination • Genetic Abnormality Detection (defects) • Trait Determination (homopolled, coat color) • EPD Accuracy Improvement (GE-EPDs)

CSA REQUIREMENTS

  1. All bulls that will sire progeny must be sire verified by DNA test before their progeny can be registered

  2. All bulls that will sire progeny must be TH tested in order to register their progeny OR  a bull whose sire and dam have both been TH tested FREE may be considered TH free by pedigree and therefore do not require the TH test. NOTE: The result of the TH test will have no effect on eligibility for registration.

  3. All Embryo calves must be verified to their Dam and Sire by DNA test Therefore, all dams and sires of embryo calves must have their DNA on record.

ABOUT "DNA"

Around 2015 the standard DNA technology used among all beef breeds became the "SNP" test. SNP (Single Nucleotide Polymorphism) technology can isolate 10’s of thousands of markers which compared to older technology (STR Microsatellite DNA) results in fewer errors and provides sufficient genomic material to produce GE-EPDs.

In 2017, International Genetic Solutions (IGS) developed GE-EPDs which revolutionize the calculation of EPDs in the majority of the breed associations in Canada, the United States and Australia. The original EPDs were created from breeders submitting birth, weaning and yearling weights. Adding DNA genomic marker data ( from SNP test samples) to produce Genomically Enhanced EPDs, has further invcreased the accuracy of the EPDs we know today. 

 

GE-EPDs are only available on animals with GGP test types such as 30K, 50K and 100K. They are distinguishable in the Digital Beef Registry by yellow highlight on the animals’ EPD figures.

Occasionally, a sire and or dam may have an old Microsatellite DNA (also known as STR) on record. SNP and STR DNA records cannot be compared. Therefore, if a parent only has an STR profile on file and is not able to upgrade to SNP, a STR will be required on the progeny so that we are able to compare to the Dam or Sire. The CSA office will advise the member if this situation arises.
