Another thing to look at is the Superior Genetics list, on the adga website under Sire development PTI index. The PTI tries to remove environmental & management variables to determine the genetic merit of an animal.
For example, a doe milking 2,500 lbs in an average management herd that averages 1,600 lbs is genetically superior to a doe milking 3,000 lbs in an excellently managed herd averaging 3,200 lbs.
You also don't want to select solely on production. The French dairies did this for a while and ended up with some horrendous results.
