The Angus Breeding Index estimates the genetic differences between animals in net profitability per cow joined in a typical commercial self replacing herd using Angus bulls.
This selection index is not specific to a particular production system or market end-point, but identifies animals that will improve overall profitability in the majority of commercial grass and grain finishing beef production systems.
The Angus Breeding Index is particularly suited to commercial producers who sell progeny into different markets, or to seedstock producers supplying bulls to commercial clients who produce for a range of different production systems and market end points.
The graph below shows the emphasis that has been placed on each trait group in the Angus Breeding Index.
The following table shows the indicative change in traits after one generation if producers select animals using the Angus Breeding Index.
The indicative response reflects the change if the Angus Published Sires (at the November 2014 Angus GROUP BREEDPLAN analysis) were ranked on this selection index and the Top 10% selected for use within a breeding program. The response will differ if a different group of animals was available for selection and/or a different selection intensity was applied.
