Docility scores taken on calves between 60 and 400 days of age are used to calculate Docility EBVs within the TransTasman Angus Cattle Evaluation (TACE).
Recording docility scores
Animals can be scored for docility using either a crush or yard test:
While docility scores from both scoring systems are acceptable, the crush test is more commonly used as animals can be scored when moving through the crush for other purposes (e.g. weighing, animal health treatments).
Docility score descriptions
When using either the crush or yard test, the behaviour of animals should be observed and animals scored using the criteria displayed in the following table.
Half scores (i.e. 1.5, 2.5, 3.5, 4.5) can be used to identify animals who exhibit behaviour which is intermediate to the scores listed.
In a “normal” Angus beef herd where the majority of animals have acceptable temperament, it would be expected that the majority of animals would have a score of 1, 1.5 or 2, with a small percentage of animals receiving a score of 2.5 and above.
When should animals be scored?
Docility scores must be recorded when animals are between 60 and 400 days of age for inclusion in TACE.
The recommended time of scoring is at weaning or shortly afterwards. The advantage of scoring at weaning is that all calves should have had minimal handling and so will express variation in temperament. Variation in handling between animals prior to scoring should also be minimised.
Only one docility score can be analysed in TACE for each individual animal.
