Sorted Lists of A.I. Bulls

Dr. Allen Young
USU Extension Dairy Specialist

    The web sites included in this month�s listing are those dealing with sorted lists of A.I. bulls. These are really good sites that make it possible to select and sort bulls of any breed using any selection criteria which you want to use.

     These sites are:
    The first three web site are databases of U.S. and International bulls. The last site is a listing of bulls by Estimated Relative Conception Rate, or ERCR. This is a measure of conception rate of females bred to a service sire relative to herdmates bred to other service sires (fertility index). Several of these sites allow you to download the database to your own computer, load it into another program such as a spreadsheet, and sort it by a criterion other than what is allowed on the Internet.

    Between these sites you can literally grab the bull by the horns and find that perfect bull for your operation. If you have any problems, give me a call at (435) 797-3763 and I�ll try to help. ©
