- 305 Day test
MDGA has two options for milk testing to prove
your miniature dairy
does’ milking productivity. We offer both an official
DHIA milk test and our official MDGA in-house milk test;
both tests are valid for evaluation for *P awards.
The rules for the Advanced Registry are currently being
updated; the updated rules will be posted when completed.
Inherited Production Stars
Does may have multiple stars. If the daughter of a *P (MDGA)
doe earns a star, the daughter becomes a two-star producer
(2*P); each generation in an unbroken line would add a star
number. For instance, the fourth doe in the line receiving a
star would be a 4*P.
1. A doe may earn a
star if she produces three daughters that earn a star (*P)
2. A doe may earn a star if she
produces two sons that earn plus (+B) awards.
A doe may earn a star if she produces two daughters that
earn star (*P) awards and one son that earns a plus (+B)
A buck may receive a star (ST) if:
Both of his parents
are star animals.
2. Both his dam and his
sire's dam have earned stars.
A buck may earn a
single plus (+) if he has progeny that are ONE of the
following, or a buck may earn a double plus (++) if he has
progeny that are TWO of *the following:
Three star daughters out of
three different dams.
2. Two sons that have earned a plus.
3. Two star
daughters from different dams and one plus son.
For One Day Testing
MDGA 305 Day Milk Testing
The MDGA Milk Committee will be implementing the
following changes, starting January 1, 2016.
The purpose of the changes is to help make the
program run more smoothly and work better for

Program, all participating herds MUST register
with the milk committee by January 15th
of the year of participation.
test must be completed no less than 25 days
apart and no more than 45.
must take place between 90 and 120 days.
The first test must be done within the first
45 days of lactation.
A list of all does intended to be on test MUST
be included with herd registration.
Participants may still eliminate any doe on the
list at any time, but may NOT add additional
ones. (With the exception of transfers from
another herd on test.)
ALL does to be tested must have their first test
by the time they are 45 days in milk, testing
must be done at least every 45 days until dry,
up to 305 days.
All test paperwork and lab sheets must be turned
in a minimum of every 60 days.
Herds registered, will receive a barn sheet with
all the doe information included to be used for
your first test. For any does not tested,
participants will draw a line through the doe’s
name and that doe will be deleted from the sheet
for the next test. Upon receipt of the first
test results, a verification form with all does
listed will be provided. Again, any doe
may be crossed out if she is to be dropped from

Individual Certificates of Production will be issued if the

To receive a *P in a one-day test, a miniature doe must
achieve a score of 70 or above, and a Nigerian Dwarf doe
must achieve a score of 55 or above.
tests will be required for all “in-house” test programs and
for all DHIA owner sampling.
Verification tests will also be required for any doe that
may be qualified for a Top Five Breed Leader designation.
If the dam of a miniature or Nigerian Dwarf is registered
with a registry other MDGA, MDGA will accept the production
records of the dam if the conditions below are met:
1. Application is made by the owner to have the dam’s record
from the other registry
2. The dam is registered with MDGA, the milk test fee is
paid, and the application is submitted to MDGA
3. Official Documentation of the dam’s record is
miniature daughter will receive only one star for her dam
once she has earned her own star. The total number of stars
of a dam will be listed on the dam’s Certificate of
herd owners who have registered for production testing with
to MDGA the right to publish all completed lactation
results. They also grant permission for these records to be
used in ways that promote the miniature dairy goat breeds

milk outs will be conducted. The first is a check,
with no samples taken. The
milk weight will be recorded but not used to calculate the

does height will be officially measured by the tester.
8. For miniature does, a score
of 70 or more points (figured to the thousandths place,
rounded to the nearest whole number) will be required to
receive a Production
Star (*P). For Nigerian Dwarf does, a score of 55 or
more points (figured to the thousandths place, rounded to
the nearest whole number) will be required to receive a
Production Star (*P).
9. Scores will be calculated
using the following formula:
a. Multiply pounds of milk by 5.55.
b. Multiply pounds of milk by butterfat, then multiply this
number by 1.11.
c. Multiply days since freshening by 0.0555.
d. Add totals for final score.
Example: a miniature
doe fresh 43 days with 5.6 pounds of milk at 4.5% fat:
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 0.0555 = 2.3865 (rounded to 2.387)
d. 31.08 + 27.97 + 2.387 = 61.437 (rounded to 61); the doe
does not receive a Star
DHIA Testing Plans
The supervisor/tester comes once a month to record milk
weight, take samples from two consecutive milkings, fill out
paperwork, and send samples to a lab. The supervisor must
adhere to MDGA rules.
Test: Owners of three or more herds may test each other’s
respective herds. These owners rotate which herd they will
test each month. They will weigh milk, take samples on two
consecutive milkings, fill out paperwork, and send samples
to the lab. Each member-owner in the group must complete
supervisor training before testing begins. A verification
test is required between ninety and 159 days fresh.
3. DHIR-21: The
supervisor collects milk weight one day, alternating the AM
and PM weighing each month. DRPC will determine the other
weight. A verification test is required.
DHIR-22: The supervisor weighs milk from both milkings on
, and also collects samples alternating
between AM-PM on alternate months. A verification test is
Sample: Owner weighs and samples all milkings on test day. A
verification test is required. Does tested by this method do
not qualify for Top Five Awards.
