The Specht Report: Prefix

Reports are based on the August 2009 official proof release. Reports are updated annually, and the next scheduled update will be August 2010.

Chad Dechow, Editor.

The top 150 prefixes sorted by adjusted Lifetime Net Merit. All traits are adjusted for the year that bull was born before the averages are calculated for a prefix.

Why adjust for a bull's birth year?

Prefixes that have sent bulls to A.I. only recently will have an advantage due to a positive genetic trend for most traits. Adjusting for the birth year of a bull rewards those prefixes that have provided bulls to A.I. over a longer period of time.
