The collection of the full suite of performance data for the Cohort 3 progeny of the Angus Sire Benchmarking Program (ASBP) has been completed. The data has been analysed in the March 2016 BREEDPLAN analysis including abattoir carcase grading outcomes and meat science laboratory results for the Cohort 3 steers, and fertility information for the Cohort 3 heifers. This is additional to the

The carcase data collected and analysed on the 580 Cohort 3 steers includes:
A summary of the carcase performance statics from the Cohort 3 steers is tabled below:
|Live Wt(kg)||Carcase Wt (kg)||Dressing %||P8 Fat(mm)||Rib Fat(mm)||Ossification(Score)||MSA Marbling (Score)||AUSMEAT Marbling(Score)||EMA(cm2)||MSA Index||IMF % Chemically Extracted||Shear Force(kg)|
The ASBP steers entered the University of New England’s Tullimba Research feedlot at around 450kg average liveweight with most steers being in the 400kg to 500 kg range. They were on feed for approximately 100 days at Tullimba undergoing Net Feed Intake testing, before being relocated to Rangers Valley Feedlot, Glen Innes for an additional 170 days to complete a total feeding period of 270 days.
Utilising the 270 day feeding period has several benefits in relation to genetic evaluation for carcase traits including:
Additionally, the natural joining outcomes on over 350 Cohort 3 yearling mated heifers (i.e. siblings of the steers) have also been collated and analysed to produce updated Days to Calving EBVs for the Cohort 3 sires. This involves measuring the days from the heifer’s first exposure to natural joining (i.e. bull in date) until to the day the heifer calved. If a heifer was exposed and does not conceive or calve then a penalty record is applied.
