Miniature Dairy Goat Association






The Miniature Dairy Goat Association registers animals that are the offspring of a registered standard dairy goat and a purebred, registered Nigerian Dwarf dairy goat. The parents of the animal for which registration application is being made must be registered as “American” or “Purebred” with one or more of the following associations: American Dairy Goat Association, American Goat Society, Nigerian Dwarf Goat Registry, or the Canadian Goat Society. (“Recorded Grades” and “Experimentals” will be covered later.)

Acceptable parent breeds for miniature dairy goats include: Alpine, LaMancha, Nubian, Oberhasli, Saanen, Sable, Toggenburg, and Nigerian Dwarf. Breeds that are NOT acceptable include: Pygmy, Boer, Angora, or any other non-dairy goat breed.

As the generations from the original crossbreeding advance, MDGA uses different categories for registrations, called “herdbooks. MDGA has four herdbooks: - “Experimental,” “American,” “Purebred” and “Grade.”

*If there is any question about a kid(s) sire, i.e. more than one buck in a doe pen, All kids will be required to have a DNA test completed as well as at least one of the bucks (if there are only 2 bucks in question) will need to be tested in order to register the kid(s).


Experimentals” are miniature dairy goats that are usually first- or second- generation miniature dairy goats (F1 and F2). These individuals do not have to meet the breed standards of their chosen breed. View the breed standards here. Any third-generation or higher miniature dairy goat that does not meet the standards for the specific breed will also be registered as an “Experimental” with an * after the registration number indicating it does not conform.


Americans” are miniature dairy goats that are usually third-, fourth-, and fifth- generation miniature dairy goats (F3, F4, and F5). Each animal MUST meet ALL standards for its specific breed and must be no more than 70% of either of the original breeds (standard dairy goat and Nigerian Dwarf). If an animal belongs to one of these generations but does not meet ALL standards for its specific breed, it will be entered into the “Experimental” herdbook instead of into the “American” herdbook with * after the registration number. This is in accordance with MDGA’s 70/30 Rule, which requires that a goat have no more than 70% or no less than 30% of either of its parent breeds in order for it to be accepted in the “American” and “Purebred” herdbooks.)


Purebreds” are miniature dairy goats that are sixth-generation (F6) or higher miniature dairy goats. A “Purebred” MUST meet ALL standards for its specified breed and must meet the conditions of the 70/30 Rule.


  1.  Fill out the registration application completely.

  2. The completed application must be accompanied by the required photographs. The first should be of the head, showing breed characteristics, and the second should be a complete side view. (Profile shots of the face are required for the Mini Nubian, third generation and higher.)

  3. All applications for registration of animals from a sire and/or dam that is/are registered with the American Dairy Goat Association, American Goat Society, Nigerian Dwarf Goat Asscoiation, The Miniature Dairy Goat Registry, International Dairy Goat Registry, or the Canadian Goat Society MUST be accompanied by legible copies of the parent’s registration certificates. TMGR & IDGR registered parents must include a pedigree that goes back to MDGA, AGS or ADGA or NDGA registered goats, or back 6 generations.

  4. If the sire of the animal being registered is not owned by the person making application, a signed service memo from the owner of the sire must be included with the application. If the animal being registered is the result of the use of frozen semen, a signed Artificial Insemination Service Memo must be submitted instead of a live service memo.

  5. When determining the generation of the animal being registered, use these guidelines:

    a.    A standard dairy goat bred to a registered purebred Nigerian Dwarf results in a first-generation (F1) miniature.

    b.    The cross of an F1 to another F1 results in a second-generation (F2) miniature.

    c.    No unregistered or grade Nigerian Dwarves can be used in the Mini breeding program.

    d.   When two animals of different generations are bred, the resulting offspring is classified as one generation higher than the lowest generation parent is. For example, the offspring of an F3 bred to an F1 would be an F2, and the offspring of a miniature of any generation bred back to a purebred standard (considered zero generation) or a Nigerian Dwarf (considered zero generation) would be an F1.


In the “Grade” herdbook, MDGA may accept for registry FEMALE animals that do not qualify to be registered in the “Experimental,” “American,” or “Purebred” herdbooks. MDGA does NOT register Grade Nigerians or offspring of Grade Nigerians.
The sire of any animal being presented for registration must be a registered purebred Nigerian Dwarf buck or doe OR a registered miniature dairy goat buck of the same breed as the dam of the animal being considered for registration. NOA or Grade standard, mini and Nigerian sires are not allowed.

If applying for an animal’s registration in the “Grade” herdbook, follow these guidelines:

1. Fill out the registration application completely.

2. Attach a legible copy of the registration certificate of any parent registered or recorded with ADGA, TMGR, IDGR, or NDGA.

3. The completed application must be accompanied by two photographs of the animal for which the application is being made. The first should be of the head, showing breed characteristics, and the second should be a complete side view.

4. NO Grade or NOA BUCKS will be allowed in the “Grade” herdbook.

5. NO OFFSPRING of un-registered, registered grade, registered NOA bucks or Nigerians will be allowed in the MDGA “Grade” herdbook.

6. Does ONLY will be accepted into the MDGA “Grade” herdbook if:

·         the doe is a result of the mating of a doe of unknown ancestry TO a registered Nigerian Dwarf or a registered miniature dairy goat buck. The breed of the animal must be listed on the application, and only that breed listed may be used for recording any future offspring of the dam of the animal being registered. The fourth-generation male and female progeny from this original unregistered doe would qualify for the “Experimental” herdbook, if and only if the UNKNOWN/3RD BREED has been bred completely out. If not the progeny will remain in the Grade herdbook until that unknown/3rd breed percentage is bred out, no matter what the generation.

Male progeny will not be registerable until the UNKNOWN/3rd breed has been bred out completely.

·  The doe is the result of the mating of a doe that is a crossbreed of two different registered standard dairy breeds bred TO a registered purebred Nigerian Dwarf or a registered miniature dairy goat buck belonging to one of the two breeds of the doe. The second and third generation female kids would also be recorded in the “Grade” Herdbook.
The fourth generation male and female kids are eligible to move to the “Experimental” Herdbook,
if and only if the 3RD BREED percentage has been reduced to 0.10% or less. If not the progeny will remain in the Grade herdbook until that 3rd breed percentage has reached 0.10% or less, no matter what the generation.

When it has a 0.10% for the unknown the male and female offspring will be registerable as a first
generation miniature dairy goat with all the normal rules and opportunities to continue through the main herdbook generations.


For a successful MDGA registration of a miniature dairy goat previously registered with another registry, the animal must conform to the rules for registering goats in MDGA and will be placed in the herdbook with which its pedigree conforms. Follow these guidelines to register your animals:

  1. Fill out the MDGA registration application completely.

  2. When submitting the application, enclose the required photographs.

  3. When submitting the application, include a legible copy of the certificate from any registry where the goat has already been registered.

  4. Include a six-generation pedigree for the non-MDGA animal for which the registration application is being made. Be sure to include the full name and registration number of each animal on the pedigree.

  5. Remember that MDGA does NOT register bucks NOA or if they are from non-registered or crossbred does.

  6.  MDGA WILL NOT register grade or NOA Nigerian Dwarves, or offspring of an unregistered or registered Grade Nigerian Dwarf

MDGA welcomes applications for registration of miniature dairy goats that are already registered with other registries. However, the person submitting the application should be aware that MDGA requirements for registration in the main herdbook or grade herdbook may differ from other organizations’ requirements. This could mean that a goat classified at a level such as “American” or “Purebred” with another organization may only be acceptable as “Experimental” based on the animal’s pedigree. This also means that some applications for registration may be turned down.

When an animal, which has already been registered, is to be transferred, the transfer portion located on the bottom of the Certificate of Registry must be completed.

Be sure that every blank is filled in and the seller has signed it. The entire Certificate of Registry must be sent to the MDGA office for recording, along with the correct fee. A new Certificate of Registry will be issued.


NOTE: If a goat is sold multiple times there is a fee for each time sold if the animal has not been officially transferred for each person sold to already.

Based on APHIS rules, MDGA is required to have animals documented for each farm an animal has lived to the best of our ability.

See APHIS rules quoted below.

“Registration/official tagging records to include to whom animals are purchased and sold to are required to be maintained for 5 years.

(d) Each person who buys or sells, for his or her own account or as the agent

of the buyer or seller, transports, receives for transportation, offers for

sale or transportation, or otherwise handles sheep or goats in interstate

commerce must ensure that the animals are identified as required in this

part and must keep records relating to the transfer of ownership, shipment, or

handling of the sheep or goats, such as yarding receipts, sale tickets, invoices, and waybills.

Remember that MDGA does NOT register either male or female offspring of un-registered, registered NOA, or registered grade bucks.



70/30 Rule

Without breed standards, there could be no consistency within the breed. Our goal is to create a multi-purpose, mid-sized goat with a true blending of Nigerian and standard breed characteristics, as the smaller size means that the animals will be easier to handle and that goat enthusiasts will gain the ability to diversify their herds.

While breeders are encouraged to work to meet breed standards in their animals, these characteristics will not always be achieved; it is up to the breeder’s discretion to decide what height, size, or breed characteristics their animals ought to possess. Consequently, an animal with a parentage of standard and Nigerian can be registered as “Experimental,” but it will not be advanced to the “American” or “Purebred” books unless it meets the standards for those breeds. Only animals with the correct percentages of standard and Nigerian blood (no more than 70% of either), size, height, and breed character will be advanced to the “American” and “Purebred” books in order to ensure quality, consistency, and endurance of the breeds.

No animal that has more than 70% of either standard or Nigerian blood will be entered into the “American” or “Purebred” books.

A high percentage of standard blood in an animal could lead to height that does not conform with breed standards.

There are NO restrictions on percentages for “Experimental” miniature dairy goat pedigrees. Only animals that are registered as “American” and “Purebred” are required to conform to the 70/30 Rule.
