There is not just one office for all of the purebred associations in the world. There are specific breed associations for example if you have Holstein cows than you need to look for the breed association in your area.
Hope this helps, if you have further questions let me know.

Dairy cattle.
Milk cattle are also called Dairy cattle or Dairy cows.
There are three main types: British, Continental, and Exotic. Of these, there are two types: Purebred and Commercial. So in all you could say there are five types of beef cattle.
Dairy cattle like Holsteins, Brown Swiss and Jerseys.
A list of 950+ purebred cattle types are at the Link. These do not include cross breeds. These cows may be generally regarded as being either meat, dairy or mixed purpose.
Dairy reproduction is the breeding and milking process of dairy cattle for the purpose of milk production.

Dairy cattle
So with 80 head of cattle, we have a 1:3 ratio of dairy to beef, respectively. That translates to: for every head of dairy cattle there are three beef cattle. Since, mathematically, 80 total head of cattle with a 1:3 ratio don't really work out to nice, round numbers, we will have to work with fractions and such. 1:3 ratio can be converted to a fraction: 1/3. 1/3=0.3333333... So, with 80 head of cattle, we find the number of dairy cattle: 80 x (1/3) = 26.66666666.... Which we could round off to 26 dairy cattle. Since we have 80 total head, we subtract to find how many beef cattle are in the herd: 80 - 26 = 54. So the answer is thus: If there are 80 head of cattle, and the ratio of dairy to beef cattle is 1:3, then there are 26 dairy cattle and 54 beef cattle.
American Dairy Science Association was created in 1906.
