The Australian Wagyu Association (AWA) has announced the implementation of its three new world-leading BreedObject $Indexes. This is a significant step forward for Wagyu breeders to achieve faster rates of genetic gain and selection for profitability in Wagyu.
Following implementation of Single-step Wagyu BREEDPLAN in April 2018, the AWA has worked intensively with the Animal Genetics and Breeding Unit (AGBU) to develop and deliver the new Wagyu BreedObject $Indexes.
The three profitability $Indexes are designed to optimise profit outcomes from commercial self-replacing, fullblood terminal and F1 terminal production systems. The three indexes are:
The AWA CEO, Dr Matt McDonagh affirmed that each of the new $Indexes are targeted specifically to a defined production and market scenario and that members should identify and use the index that best suits their purpose. It is not appropriate to compare index values of different $Indexes as they are based on different production model assumptions.
“It is not the index with the highest $ value that you should use, it is the index that best reflects your production system”.
The new Self-replacing Breeding Index can be used to select bulls that will produce more profitable females for retention in Fullblood or Purebred herds. The Fullblood Terminal and F1 Terminal Indexes can be used to select bulls that will produce more profitable slaughter progeny.
Dr Brad Walmsley of the Animal Genetics and Breeding Unit commented that “The $Indexes that Wagyu are implementing are the first publicly available indexes of their kind within Australia and the world for that matter. Wagyu are at the cutting edge of genetic evaluation, having implemented Single-step BREEDPLAN that uses genomic information and now being the first Breed Association to implement the new generation of BreedObject $Indexes.”
