There is one selection index calculated for animals recorded with the Brangus Society of South Africa.
This is the Beef Index and it relates to a typical commercial herd using Brangus bulls. The selection index is focused on efficient beef production, including maternal traits. In addition, the selection index targets the following specifications.
Beef Index - Estimates the genetic differences between animals in net profitability per cow joined for a typical self-replacing commercial Brangus herd. Steers are finished in a feedlot and are marketed at approximately 500 kg live weight (265 kg carcase weight & 5 mm P8 fat) at 14 months of age. Selected heifers are retained for breeding and the balance marketed as yearlings at 420 kg (215 kg carcase weight & 8 mm P8 fat depth). As some daughters are retained, maternal traits are also of importance.
All selection indexes are reported as an EBV, in units of net profit per cow mated (Rand) for a given production/market scenario. They reflect both the short term profit generated by a sire through the sale of his progeny, and the longer term profit generated by his daughters in a self-replacing cow herd (where applicable).
All selection index values have been derived using BreedObject technology.
More detailed information regarding the Beef selection index is provided in the downloadable document.
