TOP (Traits Other Than Production)

TOP Inspectors evaluate every LIC SPS daughter in the first 5 months of their initial lactation.

Each TOP trait is scored separately on a scale from 1-9. The traits included in the TOP system are the traits considered most Important in dairy cattle.

There are four farmer scored traits and 13 conformation traits.

An explanation of each trait is listed below with the 2000 Base Cow average raw TOP scores.

The raw data is then sent through to the New Zealand Animal Evaluation unit where within herd, region and national comparisons are analysed and processed. This information isthen fed into the national data base as breeding values for sires.
