WHAT IS HEREFORD HERD BOOK INTERNATIONAL (HHBI)?
HHBI provides a Herd Book of Hereford cattle which have satisfied the HTOPP test or an approved successor test and whose pedigrees have been registered in the official Herd Book or register of the country relevant to those Hereford cattle.
THE HEREFORD TEST FOR ORIGINAL POPULATION AND PARENTAGE ® (HTOPP)
HHBI also offers other DNA testing services such as parentage verification and genetic disease screening.
The HTOPP test was developed to determine whether an animal's DNA identifies it to be within the Original Population of Hereford cattle, or within another known or unknown population. This test is available to Hereford breeders all over the world using DNA sampling by hair or tissue.
