Australian Stud Book

The Australian Stud Book (ASB), is the body responsible for ensuring the integrity of Thoroughbred breeding in Australia.

These books are now over 3,000 pages, with volume 42 of the ASB containing the breeding records of 43,000 mares and 70,000 of their named offspring.

[1] Basic horse information is free, but there is subscription access to the Stud Book website where extensive data is available for a modest fee.

The Stud Book of New South Wales by Fowler Boyd Price was published in 1859, and was the first official attempt to document the pedigrees of the colony's bloodhorses.

Exceptions to this include the following early Colonial mares which did not trace to the General Stud Book (GSB), but are accepted by the ASB owing to the performances of their progeny: Some mares that were included in the American Stud Book are exempt.

[5] Prior to 1980 it was not uncommon to see a country racehorse registered as "by an unidentified sire out of a station mare".
