MDGA Milk Testing

1 Day Testing

Welcome to 1 Day DHIA Testing

1 Day testing is perfect for those wanting to prove how much their doe makes in a milking as well as gather components on a doe’s milk. 1 Day tests are eligible to earn a star (ST) on the doe’s certificates provided they meet MDGA minimum requirements of 70pts. 

To perform a 1 Day test, owners will need to have a certified Supervisor, a calibrated/certified scale and will need to perform 3 supervised milk outs recording the weights and taking samples to be sent to the lab of your choice. The lab will analyze the samples and send MDGA the completed paperwork which will be processed by the Milk Committee team and the owner will be notified within 2 weeks if their doe(s) earned a star.

For 305 participants, the Verification Test is performed the same as a 1 Day test. The owner must have a separate Supervisor for their Verification Test. 

It is the responsibility of the herd owner to make sure that the completed 1 Day permit or Verification Test form along with Lab results be sent to MDGA.  You may take a picture or scan the completed form and send to the milk test email.

1 Day Milk Test Fees

  • $10 Fee + $3 per doe

    Each time a 1 Day test application is submitted, both fees need to be submitted. 


Calculating Results for 1 Day Test

For miniature does, a score of 70 or more points will be required to receive a Production Star (*P).

For Nigerian Dwarf does, a score of 55 or more points will be required to receive a Production Star (*P).

1 Day Test scores will be calculated using the following formula:
(to the thousandths place, rounded to the nearest whole number)

a) Multiply pounds of milk by 5.55
b) Multiply pounds of milk by butterfat then multiply by 1.11
c) Multiply days since freshening by .0555
d) Add the totals of a, b & c for a final score.

A doe who is 43 days fresh with 5.6 lbs. of milk and 4.5% butterfat:

a) 5.6 x 5.55 = 31.08
b) 5.6 x 4.5 x 1.11 = 27.9720 (rounded to 27.97)
c) 43 x .0555 = 2.3865 (rounded to 2.387)
d) 31.08 + 27.97 + 2.387 = 61.437 (rounded to 61)

As a miniature dairy goat, this doe would not qualify for a star as she did not reach 70pts. As a Nigerian Dwarf, the doe would receive a star as she was over 55pts.

How To Perform a 1 Day Test
or Verification Test

**Please read the 1 Day Milk Test Rules packet as the website does not have 100% of the information posted.

This is a typical 1 Day Test outline as well as a Verification Test outline (they are performed the same) to give an idea of what to expect on your test days.

For a 305 Verification Test (if needed for your plan), which is performed when the MAJORITY of the herd is between 60-150 days in milk, if the owner is on OS40 (Owner Sampler), a seperate Supervisor will need to perform the Verification Test. 

The evening before, or 12 hours before the official test start, milk out the does completely while the Supervisor records all pre-milk out weights for each doe.

*Please Note* Pre-Milk out weights MUST be recorded on the 1 Day or Verification Test forms to be accepted as a completed test.  

The next morning, after pre-milk out (approx 12 hours), the owner and the tester will proceed to start the test. Have all paperwork, certified scale, measuring stick, and a flashlight or microchip reader ready. The general steps for performing your test are as follows:

    1. The supervisor verifies the tattoo/microchip for your first doe.
    2. The supervisor measures and records the height for the doe on the MDGA form.
    3. Supervisor writes the start time of milking on the paperwork then owner milks the doe out fully.
    4. Once milked, the supervisor weighs the milk and records the weight.
    5. Supervisor will take sample from milk to fill half of the sample vial.
    6. Supervisor will label the sample vial with the index # for that doe.
    7. Repeat 1-6 for each doe on test.
    8. Supervisor writes the end time for milking on the paperwork once all does have been milked.

Once all does have been milked out and sampled, the owner and the supervisor will check to make sure all data recorded is correct. If correct, the first half of the test has been completed. The supervisor will return in the evening approx 12 hours later.

For the evening milking, proceed with the following to finish the test:

    1. The Supervisor records the starting milking time and proceed to milk the first doe.
    2. Once milked, supervisor weighs milk and records the weight.
    3. Supervisor will take sample from milk to fill the rest of the doe’s sample vial.
    4. Repeat 1-3 for each doe on test.
    5. Write down the ending time on your paperwork once all does are milked out.

Check over all paperwork and samples, if everything is correct, the supervisor signs the paperwork and the samples are mailed to the lab with all paperwork. It is advisable that copies should be made prior to shipping and sent in to MDGA milk test email within 48 hours of test. Then all paperwork should be placed in the shipping container and sealed and mailed to the lab, by the tester.

The lab will then test the milk and send test day results to the herd owner and MDGA only if requested by the herd owner. Once MDGA recieves the Lab Results, the milk test committee will process your test and will email results within 2 weeks. If the doe meets qualifications, that doe will recieve a digital certificate with the test results.
