Subjective structural soundness scores collected by an accredited scorer when animals are younger than 750 days are used to calculate Structural Soundness EBVs within the TransTasman Angus Cattle Evaluation (TACE).
Recording structural soundness scores
Structural soundness scores for TACE are collected using the Beef Class Structural Assessment System. Scores are collected for 5 traits related to feet and leg structure using a 1 – 9 scoring system, where
Use of accredited technicians
Structural soundness scores for TACE must be collected by an accredited technician. A list of accredited technicians can be accessed from the TACE area of the Angus Australia website, or by contacting staff at Angus Australia.
Structural soundness scores not collected by an accredited technician will not be included in TACE.
When should animals be scored?
TACE can analyse structural soundness scores from animals that are less than 750 days of age at scoring (i.e. 25 months). The majority of animals are scored as either yearlings or rising 2 year olds.
Animals should be scored either prior to, or on the same day as the collection of a 400 or 600 day weight for TACE.
The most recent 400 or 600 day weight contemporary group forms an important criteria in determining the contemporary group in which structural soundness scores are analysed. Structural scores can only be analysed in TACE for animals that have a prior 400 or 600 day weight included in the analysis.
Structural soundness scores can be collected on mature cows but are not currently utilised in the calculation of Structural Soundness EBVs.
