The 2011 Guernsey Component Queens were compiled from all 305-day DHI and DHIR lactation records received and made official by the American Guernsey Association. To be considered official for production recognition programs and awards, the cow must have had at least 8 test days with components measured for a 305D record and 9 test days with components measured for a 365D record. The Component Queen designation recognizes the top 100 lactations completed in 2011 for combined fat and protein.
