OUR EBV APPROACH
EBVs and data don’t always tell the full story.
But there is no denying that good data is now an essential part of breeding elite Angus cattle.
We don’t breed for data, but ensuring the cattle we sell feature good numbers is now an important objective.
We use custom-built software which analyses EBV data and optimises our breeding decisions to ensure we produce quality, structurally sound, phenotypically appealing cattle that also have strong, balanced EBV profiles
THE 50th PERCENTILE
Angus Australia EBVs are measured in percentiles.
The 50th percentile indicates the ‘median’ or ‘middle of the road’ registered Angus animal.
Think of this as an approximation of the ‘average’ of the breed.
Comparing how many points above or below this 50th percentile our herd is lets us measure if that herd is above or below the median for each trait.
THE JACKAROO HERD
AN AVERAGE OF EVERY SINGLE ANIMAL IN OUR CURRENT HERD

Our focus on breeding growthy, easy-calving, structurally sound cattle with suitability and high profitability for many operators' objectives - with calving, growth, and index EBVs our highest scores and well above breed average.
+8 PERCENTILE POINTS HIGHER THAN MEDIAN ACROSS ALL EBVS
+14 PERCENTILE POINTS HIGHER ACROSS ALL SELECTION INDICIES
HIGHER THAN MEDIAN ACROSS 28 OF THE 35 EBVs AND INDICIES
JUST THE BULLS
AN AVERAGE OF EVERY MALE ANIMAL IN OUR CURRENT HERD

THE AVERAGE JACKAROO BULL HAS GROWTH EBVs +27 PERCENTILE POINTS ABOVE BREED MEDIAN FOR GROWTH, AND +24 PERCENTILE POINTS HIGHER FOR SELECTION INDICIES AS WELL AS A STRONG EBV PROFILE ACROSS THE BOARD
Some of our top end bulls have stronger numbers, some have weaker - but this shows the high average standard across our entire program.
THE NEXT GENERATION
AN AVERAGE OF EVERY ANIMAL IN OUR CURRENT HERD BORN IN THE LAST 12 MONTHS

+15 PERCENTILE POINTS HIGHER THAN MEDIAN ACROSS ALL EBVS
+30 PERCENTILE POINTS HIGHER ACROSS ALL SELECTION INDICIES - MEANING ON AVERAGE, OUR NEW CALVES ARE IN THE TOP 20% OF THE BREED ACROSS ALL SELECTION INDICIES
We are trending in the right direction and we are continuing to improve and elevate our herd and the genetics of our breeding program.
