Mature cow udder scores assess the structural soundness of the udder on mature females, and are measured as visual scores.

Mature cow udder score data does not need to be collected by an accredited scorer.

Recording mature cow udder scores

Mature cow udder scores are collected for 3 traits, related to udder conformation based on the visual appearance of the animal.

Each trait uses a 1-9 scoring system, where:

• A score of 5 is considered ideal
• Scores of 4 and 6 show slight variation from ideal, but this includes most animals. Any animal scoring 4 and 6 would be acceptable in any breeding program
• Scores of 3 and 7 show greater variation, but would be acceptable in most commercial breeding programs, however seedstock producers should be wary
• Scores of 2 and 8 are low scoring animals and should be looked at carefully before purchasing
• Scores of 1 and 9 should be considered culls

If there is variation from teat to teat, the score that is recorded should reflect the worst teat.

Use of accredited technicians

Contrary to the collection of feet and leg scores on young animals, mature cow feet and leg scores do not need to be collected by an accredited scorer, although an accredited scorer can be used if that is preferred.

Once sufficient scores have been collected, research will evaluate the usefulness of breeder collected scores for genetic evaluation versus those collected by accredited technicians.

When should mature cow feet and leg scores be collected?

Mature cow feet and leg scores, relating to feet and leg structure, can be taken at any time throughout the year. Only one score per year is required.
