Arranging cooperative relationship among parties concerned, we promote "posterity examination" in order to select dairy and beef sire which can be used all over Japan.
As for cattle, artificial insemination technology being prevailed, lots of semen, taken from excellent sire, are in use. That is why it is important to select excellent sire by judging their ability properly. While the potential productivity of milk or meat, which sire have in their gene, can not be directly estimated, we have to judge after the ability of the prosterity (children) are proven in a number of examples.
