DNA Designators Explained

AKGA certificates display the DNA status of every goat within the pedigree, indicating the number of generations of DNA testing and parentage qualification.


Genotyped: (GT) Refers to that goat having its DNA markers on file with the DNA testing lab. This simply places the goat’s genetic makeup on file with the lab for future comparison of progeny to qualify parentage of progeny.


Sire Qualified: (SQ) The goat has been DNA tested and qualifies as an offspring of the stated sire.


Dam Qualified: (DQ) The goat has been DNA tested and qualifies as an offspring of the stated dam.


Parent Qualified: (PQ) The goat has been DNA tested and qualifies as an offspring of the stated sire and dam.


If there is no DNA qualifier next to a goat’s registration number on the certificate, this means no DNA has ever been placed on file for the goat. This does not mean a sample cannot be submitted at any time, to place that goat’s genetic markers on file with the lab, for future parentage testing of progeny.

AKGA DNA Services

The AKGA has the largest repository of Kiko goat DNA information in the world and offers both DNA parent qualification and Alpha s1 Casein testing to members and non-members and at reduced rates to its members.

Parentage DNA Testing:

DNA parentage testing can be ordered at the same time registration is applied for by marking the appropriate spaces on the registration application and the fees and order form.

 

To order a DNA kit for a previously registered animal that has not been DNA parentage tested, please submit the goat's AKGA registration certificate, mark the space “DNA Genotyping / Testing” on the Fees & Order form and mail them, along with the appropriate fees, to the address on the form. No certificate copies will be accepted.  Copies will only delay your request.

 

To order a DNA kit for parentage testing for a goat that has not been previously registered and you do not wish to register at this time, please complete a goat registration application, with as much information as possible.  Write, “DNA Request Only – No Registration” at the top of the application and mail it, along with a Fees and Order Form and the appropriate fees, to the address on the forms.  To order a DNA kit for parentage testing for a goat that has not been previously registered and you do not wish to register at this time online, please fill out the online registration application and submit it.  (Note – many fields on this form are required and you will be unable to submit the application online if any of these fields are left blank.)  After submitting the application online, please email the AKGA Registry Office at mailto:akgaregistry@gmail.com and inform the Registry Manager that the online registration application submitted is for DNA parentage testing only, referencing the goat’s name.

Alpha s1 Casein Testing:

Alpha s1 Casein is one of the four casein proteins found in goat's milk.  The Alpha s1 Casein gene (CSN1S1) that produces the protein shows polymorphisms which affect the amount of protein and fat produced.  DNA tests have been developed which can allow breeders to select production levels of Alpha s1 Casein.  This test has been utilized by the dairy goat industry for many years, in breeding strategies for developing goats with higher fat and protein content for cheese making, or lower fat and protein content for those who are “milk sensitive.”    

 

An Alpha s1 Casein report would appear as follows with Animal information:

ALPHA s1 CASEIN
A/E

Interpretation of result code:

Variants, A and B, are associated with a high content of alpha s1 casein in milk. Variants, E, F and N, are associated with a lower content of alpha s1 casein in milk. Any combination of A and B variants will produce high amounts of alpha s1 casein. A combination of A or B variant with E, F or N variant will produce intermediate amounts of alpha s1 casein. Any combination of E, F and N variants will produce low amounts of alpha s1 casein.

The animal above, if a doe, would be expected to produce intermediate levels of the casein and pass on either the A or E to their offspring. The animal above, if a buck, would have daughters that would inherit either the A (high level) or E (lower level). The variant inherited from their dam would determine whether they were an intermediate or high level producer of casein.

 

This test if offered to AKGA members as an added breeding strategy for herd improvement and/or culling factors.  The cost of this test to an individual is $50.00 per test.   See the Fees and Order form for pricing of this test for AKGA members.

 

If you have submitted a DNA sample to UC Davis/VGL for Genotyping or Parentage Qualification in the past, a new sample is not required to run the Alpha s1 Casein testing on that goat. 

 

Alpha S1 Casein testing can be ordered at the same time as parentage DNA testing, by marking the appropriate space on the Fees and Order form. 

For ordering Alpha S1 Casein testing on goats that have been previously DNA parentage tested, mark the appropriate space on the Fees and Order form or the online payment form and complete the below form:

Alpha s1 Casein Testing Form

If prepaid, the form may be scanned and emailed directly to the Registry Office at akgaregistry@gmail.com  or may be mailed directly to the Registry Office at:

AKGA Registry

56 Whitney Court

Cleveland, GA 30528

 

If sending payment with the form, please enclose a Fees and Order form with the completed Alpha S1 Casein Testing Form and mail to the address on the form, along with the appropriate fees.  A new sample is not required to As1C test goats previously parentage DNA tested.
