PERFORMANCE REPORT Top 25 Records in History and National Class Leader List The Top 25 Records for Milk, Protein and Fat completed in the history of AJCA production testing programs are listed below. The National Class Leader List summarizes the 10 highest lactations for milk, protein, fat, and cheese yield in nine age categories. Lactations are 305 days (or less) in length and are official on the AJCA records. These lists include lactations added to the database through February 1, 2022. To qualify for these lists, all test days
included in a completed 305- or 365-day lactation record must occur in a herd or herds enrolled in the Production Records Plus, TPE-Plus, REAP Plus programs, or be a Generation Count {4} or higher for registration status. An asterisk in the column after days milked indicates that the animal was milked more than twice daily during part or all of the lactation. A “V” following the record indicates that it has been verified.
