The "Spring 2010 AI Bull Census" is now available. It is a list of the "top" available AI sires ranked on $$ value for milk, fat, and protein. Holstein, Ayrshire, Guernsey, Brown Swiss and Jersey sires are included in the evaluation.
A sire must have 20 daughters with completed records to be published.
The list calculated and compiled by the Animal Breeding Group in the Department of Animal Science at Cornell University.
