ASBP – Cohort 6 Structural Soundness Data Analysed

July 31, 2018 10:36 am

In the June 2018 Angus TACE analysis structural soundness scores from Angus Sire Benchmarking Program (ASBP) Cohort 6 progeny have been analysed, producing Structural Soundness EBVs for the ASBP Cohort 6 sires. 

This included feet and leg structural soundness scores, evaluated using the Beef Class system (figure 1), on 1,112 progeny. The steer progeny were assessed following approximately 100 days on feed around 16 months of age, while the heifers were assessed on farm at approximately 18 months of age.

A list of the “top 10” Cohort 6 sires for each Structural Soundness EBV is shown in tables 1 to 5. You can also access, search and sort the structural EBVs for the full list of sires CLICK HERE 

Structural Soundness EBVS are interpreted as estimates of genetic differences between animals in desirable feet and leg structure. A higher EBV indicates that an animal will produce a higher percentage of progeny with desirable structure. There are five Structural Soundness EBVs produced being:  

  • Front Feet Angle (FA) 
  • Front Feet Claw Set (FC) 
  • Rear Feet Angle(RA) 
  • Rear Leg Hind View (RH) 
  • Rear Leg Side View (RS) 

Additionally, across Cohorts 1 to 6 of the ASBP 5,142 progeny have been assessed for the for structural soundness traits and analysed through Angus TACE. The score distributions for each trait is shown in figure 2 to 6.
