aAa codes
You can locate the aAa code on our active bulls where the Dairy Sires Catalogues, also you can list them by aAa code.
The aAa numbers are listed in the order in which the bull can best sire that particular trait. For example, a bull whose aAa number is 216345 means this bull will sire daughters that are tall and dairy with some style. When using a cow's aAa number for mating, the numbers are listed in the order in which she needs improvement most.
