At the 2009 Board meeting, a system to recognize extreme records was implemented. Those with extreme test day values will carry a label with the lactation information on the Breed Leader List.

This labeling will provide even more information to users of ADGA performance records, specifically Top Ten records.  Cut-off parameters have been developed by the Production Testing program.  Many years of data was provided by AIPL, broken into 5 day segments with range, mean and STD for milk fat and protein.  These segments were then combined into 6 groupings.  Three standard deviations were determined and used as the cutoff level.    In each group, the highest value (separating first fresheners from others) was used to provide the following charts.

During the Top Ten determination process, if extreme data (based upon the chart) is found, the herd owner will be notified that the particular doe has extreme test-day data which would qualify the record for a label.  Some producers may feel that the extreme data in their doe’s production may not be accurate.  With the preliminary process used for identifying Breed Leaders, the member may work with their record center to have such data removed if desired with a recalculation of the record.  Others are justly tremendous producing animals and that recognition can be useful for those looking to increase production in their herds.

Following this notification and any recalculations, any lactation record that still contains extreme test-day data will carry a label.  This label will let users of the information know that the record contains some extreme test-day data and that further information with specific test day data, such as frequency of testing, level of supervision, number of milkings weighed and sampled, milk, fat and protein measurement, and more is available at CDCB.
