Wagyu Feeder Check – Empowering the Cattle Industry for Sustainable Feedlot Efficiency and Profitability
Wagyu Feeder Check is a genomic tool developed alongside CSIRO in partnership with the Australian Wagyu Association (AWA), aimed at improving the resilience and sustainability of Australia’s Wagyu beef export sector.
Wagyu Feeder Check is a commercial DNA genomic test designed for Wagyu content beef cattle to determine low genetic merit animals and help eliminate these from long-fed feedlot finishing programs. This genomic test will optimise resource use efficiency, increase drought adaptability, and improve profitability and resilience in the high-value Australian Wagyu Beef export beef sector.
Wagyu Feeder Check reports genetic merit for five traits; Feedlot Average Daily Gain, Carcase Weight, Subcutaneous Fat Depth, Eye Muscle Area and Marble Score. Additionally, a Wagyu Feeder Index is reported, predicting the overall commercial value ranking of each individual animal in a typical Wagyu long fed feedlot finishing program, based on the respective animal’s genetic merit across all five individual traits.
The genetic merit for each trait is provided as a Trait Ranking from 1 (lowest/worst performing) to 10 (highest/best performing) animal, while the Wagyu Feeder Index is provided as a ranking between 0 (low/worst) to 100 (high/best) the Wagyu Feeder Index.
The five reported traits, along with the Wagyu Feeder Index, are defined in the following table:
|Carcase Weight (HCW)
|Higher Carcase Weight rankings indicate the animal is expected to have heavier hot (or unchilled) carcase weight after slaughter.
|Subcutaneous Fat Depth (P8FAT)
|Higher Subcutaneous Fat Depth rankings indicate the animal is expected to have less subcutaneous fat depth over the rump at the P8 measurement site.
|Marble Score (MARB)
|Higher Marble Score rankings indicate the animal is expected to have a higher AUSMEAT marbling score.
|Eye Muscle Area (EMA)
|Higher Eye Muscle Area rankings indicate the animal is expected to have more muscle, and a larger eye muscle area.
|Feedlot Average Daily Gain (ADG)
|Higher Average Daily Gain rankings indicate the animal is expected to have higher rates of weight gain across the whole of the feedlot finishing period, due to superior growth potential.
|Wagyu Feeder Index (WFI)
|Higher Wagyu Feeder Index rankings indicate the animal is expected to have higher overall profitability in a typical Wagyu long fed feedlot finishing program, based on their genetic merit across all five individual traits.
Sire verification will also be provided for any progeny of sires that have genomic profiles recorded with the Australian Wagyu Association.
Ordering Wagyu Feeder Check:
Wagyu Feeder Check is ordered through the Australian Wagyu Association (AWA).
Before an order can be placed, you need to
- a) become a member of the AWA (if you aren’t already), and
- b) create an account on the Wagyu Feeder Check database (click here).
Once you have done this, you are ready to submit your request to the AWA through the Wagyu Feeder Check database. Once your request has been lodged, you need to send your samples to Neogen with the required documents for processing.
Once your results are ready, you will receive an email notification telling you that you can access your results from the Wagyu Feeder Check database.
The Turnaround Time (TAT) depends on various factors, but would generally be around 4 – 6 weeks from order submission. Please keep in mind that a small number of samples may fail genotyping and need to be re-run. We call this a retest. In that case, the TAT will of course be extended.
