Confirmed Genetic Abnormality Carriers

To access a list of known genetic carriers please use the following links.

Hypotrichosis

Partial to almost complete lack of hair. Affected calves are often born with very short, fine, kinky hair that may fall out leaving bare spots or areas particularly susceptible to rubbing. The condition may vary in expression as the animal matures and is usually less noticeable in older animals. The haircoat color will sometimes appear "frosted" or "silverish." Tail switch may be underdeveloped.

Dilutor

Carrier Hereford bulls or females when mated to black cattle can produce offspring with a haircoat that is gray, smokey or chocolate color.

Idiopathic Epilepsy

Age of onset or first seizure can be variable, ranging from birth to several months of age. Occurrence and persistence of seizures may be influenced by environmental stressors such as temperature extremes or increased physical activity. Upon initial onset of seizure episodes individuals will typically lie on their side with all limbs extended in a rigid state. Manual flexing of the limbs is possible, but return to the extended position occurs after release. Seizure episodes may last from several minutes to more than an hour.

When conducting online searches, you may see animals which have codes listed in curly brackets {} between the animal and registration number. These codes represent either awards the animal has received or genetic abnormalities the animal is known to be tested free of or a carrier of. Currently used codes are listed below.

  • DOD=Dams of Distinction Award
  • SOD=Sire of Distinction Award
  • CHB=CHB Sire Award
  • HYC=Hypotrichosis Carrier
  • HYF=Hypotrichosis Free (tested and results indicate animal is not a carrier)
  • DLF=Dilutor Free (tested and results indicate animal is not a carrier)
  • DLC=Dilutor Carrier
  • IEF=Idiopathic Epilepsy Free (tested and results indicate animal is not a carrier)
  • IEC=Idiopathic Epilepsy Carrier

DNA Fee Increases

 Effective Sept. 1, 2015, the cost of the basic DNA profile also known as a parentage SNP profile will increase to $38. The cost of GE-EPD (genomic-enhanced expected progeny difference) tests and combination packages of GE-EPD test with the basic DNA profile or horn/poll tests will remain the same as they have been since late 2014.
