Performance Improvement 

The Performance Improvement Committee is geared to helping Georgia Dairy Goat owners  improve their herds.  This can be done through milk test, linear appraisal, and genetic testing and selective breeding.

If you have any questions about getting your goats registered for Linear Apprasial or being placed on milk test, or other methods of improving your herd, please contact the Performance Improvement Chair De Cannon at



he ADGA linear appraisal system evaluates    individual type traits that affect structural and  functional durability in order to take full advantage of the potential for genetic improvement through selection.  ADGA’s linear system:

  • Evaluates each animal & trait individually
  • Evaluates each trait from one observed biological extreme to the other
  • Includes traits that have economic importance and are at a minimum, moderately heritable
  • Applied uniformly

The linear appraisal system includes 13 primary traits, one secondary trait, a research trait as well as structural categories scored by the appraiser to evaluate functional conformation on mature does and bucks.  

Producers have the information to make a more accurate selection of breeding stock than ever before. Because of this, the responsibility and the opportunity for breed improvement are directly upon breeders.

The seedstock breeder, hobbyist & the commercial producer can all benefit from selecting stock based on fact; not just guesswork as the “eye” sees it.
