You are referring to the different codes on the registration papers?
*M refers to a doe having been either on milk test and achieving a certain minimum production or on a one-day test and earned a certain number of points. The production standards for breed and age can be found in the ADGA Guidebook. If there is a number in front of the *M such as 3*M, it refers to how many generations in a row there has been a *M. For instance, in the case of a 3*M, the doe, her dam, and her dam's dam have all met the requirements for the *M.
*B refers to a buck in which both parents have a performance designation.
+B refers to a buck that has three daughters by three different does that each have met their *M requirements. It can also refer to a buck that has two sons that each have three daughters that have met their *M requirements. If a buck has both, he is a ++B. If his parents both have a performance designation in addition to everything else, he is a ++*B.
AR is an abbreviation for "Advanced Registry" which means the performance designation was a result of being on DHI test.
ST refers to the Star volume, and indicates that the performance designation was a result of either a one-day milk test, or an owner-sampler test program.
LA and the year refers to a linear appraisal record for the year printed on the papers.
CH means the animal has earned a permanent championship designation. There are a few different ways to do that, but the animal has to earn three qualifying championship legs under at least two different judges to earn this designation.
GCH means that the animal has a performance designation in addition to being a permanent champion.
SG stands for Superior Genetics. This means that at some point in the goat's life, he or she has been in the top 15% of genetic estimates.
SGCH means that the goat has both a Superior Genetics designation and is a permanent champion.

If you have further questions, feel free to ask. If you join ADGA, they will send you their guidebook, and that contains detailed descriptions of all that I have mentioned above.
