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

When should mature cow udder scores be collected?

Mature cow udder scores for udder characteristics should be taken within 24-48 hours of calving, in association with collection of calving ease and birth weight data for the cow’s progeny.
