The updated catalogue for the Herefords Australia Super Sires Program has been released and is now available to view online.
Breeders of candidate bulls who met the initial selection criteria were notified at the beginning of December and given the opportunity to nominate one of their eligible bulls for the program.
Six sires who met the initial selection criteria have been nominated for the program: Ravensdale Spark M037, Glentrevor Trust N909, Wirruna Pilot P054, Elite M202 P101, Tarcombe McLaren Q203 and Injemira Redford J006 Q287.
These six sires have now been catalogued along with the original Super Sire candidate, Wirruna Matty M288.
Once a nominated bull is accepted into the Super Sires program, he will remain classed as a Super Sire regardless of future changes in his EBVs or indexes.
The selection list for phase two of the Super Sire Program will be generated twice a year at the beginning of December and the beginning of June.
