You start getting benefit from ASBVs when you have a complete generation of records. This is when animals first recorded as lambs become parents themselves. The ASBVs increase in accuracy and predictive power considerably.
It will usually take about two to three years to build up the useful bank of information however, previous years information can be added to speed this up.
With LAMBPLAN/MERINOSELECT you can add previous year’s pedigree and performance information at no cost. This option enables a build-up of data, therefore ASBVs are more reliable within a shorter time period.
