Subjective structural soundness scores collected on animals are used to calculate Claw Set, Foot Angle and Leg Angle 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 using a 1 – 9 scoring system, where;
Front and rear feet should be scored separately.
When should animals be scored?
TACE can analyse structural soundness scores from animals older than 320 days of age at scoring (i.e. 10 months), with an animal able to be scored multiple times across its life.
Scores on both young animals, and mature females can be analysed. In general, scoring animals once as yearlings (or rising 2 year olds), and mature females once per year is recommended. Scores can be collected at any time throughout the year.
Use of Accredited Technicians
Both breeder collected scores and scores collected by accredited technicians are analysed in TACE.
It is suggested that independent accredited assessors are used for the collection of scores on sale animals, or in situations where the breeder is not confident with scoring their animals.
A “Paddock Guide to Structural Scoring for Genetic Evaluation” is available from Angus Australia to assist any breeders wishing to collect structural scores for their animals.
