This is the ideal cow to me.

I had to go to the Italian Chiania Association to find a pic. These are about gone in the US these days. To be registered as a full blood Chiania (like the one pictured) the animal as to be 100% Chiania. To be registered a pure blood, it iust has to be at least 87.5%...7/8ths...Chiania. And like a lot of breeds in the US, nearly all the purebreds you can find are black.
A Chi-Angus has to be at east 6.25% Chiania, but less than 87.5%. I am posting a link, and on it you will see registered pb Chiania, and registered Chi-Angus. I can't tell the difference, myself, without reading the titles of the pics.
