$619 per carcase – This was the difference revealed in a recent analysis of carcase data collected in the Angus Sire Benchmarking Program (ASBP) when comparing carcase values, on a progeny average basis, between the highest and lowest ranked sires. On an individual carcase basis, the difference between the highest and lowest valued carcase was $2,076.
The progeny average carcase values were derived by applying current day industry based parameters to each steer carcase (n=283) from Cohort 4 of the ASBP. The parameters are based on a general long-fed production system (200+ days) with the aim of producing and selling high quality Angus beef products. The specific parameters applied were:
Additionally, progeny average values, including Carcase Value ($), are calculated using a least squares means (LSM) model which takes into herd and other contemporary group effects.
As expected, the sires with the highest carcase value progeny averages had progeny with higher carcase weights, coupled with higher marbling scores and rump fat in the optimum range. For example, the sire ranked 1st with a carcase value progeny average of $3,511 had a carcase weight, MSA Marbling Score and Rump Fat progeny averages of 423 kg, 581 score and 15.4 mm respectively.

The outcomes show that there is ample scope to select Angus sires and genetics for the component traits that impact on the overall value of Angus carcases such as carcase weight and marbling score. Importantly, the corresponding EBVs available for selection decisions, being the Carcase Weight EBV and Intramuscular Fat (IMF) EBV, have a strong, positive relationship with the progeny average values as shown in figure 3 for carcase weight and figure 4 for IMF EBV to MSA Marbling score. Angus breeders with a goal of genetically improving carcase value should therefore have confidence in utilising related EBVs in their selection decisions.
You’re invited to attend the Angus Sire Benchmarking (ASBP) and Cohort 6 steer viewing on Thursday the 30th of November, at the Tullimba Research Feedlot, Torryburn NSW from 2.30 – 4.30pm.
Why Come and look?
1. Learn about the latest Angus R&D.
2. Hear from Dr Linda Cafe (NSW DPI) on the Retail Beef Yield project.
3. Inspect approximately 300 ASBP Cohort 6 steers identified to their Angus sire.
4. See the Tullimba GrowSafe feed intake facilities in action.
5. View 3D camera technology that assesses muscle score and rump fat on the live steer.
Who is invited?
The day is open to ALL beef producers and industry representatives.
What is the ASBP?
The Angus Sire Benchmarking Program (ASBP) is a major R&D initiative of Angus Australia with support from MLA and industry partners such as Vetoquinol, Rangers Valley Feedlot and John Dee Abattoir. The objectives of the ASBP are:
