MDGA Registration

Purebred Herdbook

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

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 “Purbred” 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.


Important Terms to know

Grade Foundation Doe:
A goat from unknown pedigree, or partially unknown. May be a recorded grade or registered Experimental with ADGA, or be an unregistered doe.

MDGA Experimental:
MDGA considers offspring of 2 registered parents, in most cases a reg. Nigerian Dwarf & a reg. standard dairy goat (ADGA – American or ADGA/AGS – Purebred) to be a 1st gen Experimental. A 2nd gen Experimental would be the offspring of a registered 1st gen Experimental crossed with a reg. 1st gen or higher Mini of the same breed.

Herdbook Changes
The Experimental, American, Purebred Herdbook WILL NOT be closing. Any Herdbook changes are to the GRADE Herdbook ONLY.
