Stock EBVs

In our opinion we believe Wagyu EBV’s should be used as a rough guide only.

We have seen in 2018 alone bulls marbling and TCI EBV’s plummet greater than a stock market crash, and that does not give any confidence to the buyer of quality genetics.

Investments made in top quality 100% full blood Wagyu genetics are an expensive exercise.

When one buys bulls from proven female bloodlines we note the marbling EVB’s do not fluctuate as much as buying bulls with  so called great EBV’s only to find they fall substantially when progeny are slaughtered and the carcasses are evaluated.

These comments have been confirmed in the latest AWA EBV figures released, and persons have paid top dollar for genetics at the AWA sale and within 2 weeks of the auction the new AWA  released EBV’s show a sizable decrease in the EBV’s of the animals purchased.

We are told to buy genetics with a high accuracy percentage EBV, well again the Wagyu industry EBV’s fall in a hole because even sires (Bulls) with a high accuracy percentage EBV have shown to fall with massive slides in their EBV’s from one month of AWA  EBV’s to the next.

We do not believe the Wagyu breed EBV’s can be used as being genetically correct.

Bulls with progeny tested can be in feedlots for different amounts of time 300 days, 400 days, 500 days, 600 days, and 700 days.

As you all are well aware most progeny are back grounded prior to going to the feedlots to start with, but you cannot put progeny of a bull that is in the feedlot for 600 days, up against progeny of a bull that has  been in the feedlot for 300 days, and for example they both marble at +8 when slaughtered, the 300 Day bull’s progeny are superior by far,

In our opinion, that is why EVB’s are so far out when it comes to a bulls true marbling EBV’s.

So we believe buying bulls from proven female family bloodlines is a safer Wagyu genetic investment than buying on just EBV’s and find later their progeny don’t stack up.

Remember you cannot take the blood out of the bull, but the EBV’s can drop out of sight when allocated an EBV value that is based on genetic algorithm theory not proven ,and what is expressed to be taken as a Guide only! Proving the Wagyu Breeds EBV’s are not accurate even when they have a high accuracy % figure.

We note that proven top blood EBV’s are not as volatile and do not fluctuate like EBV’s given to high performance Full blood TCI animals.

These high performance Full blood TCI animals seem to change their EBV value month by month and it does not give stud breeders any confidence in breeding good  FTCII EBV animals with down grading happening on a regular basis.

As for new investors who buy stock at auction, pay top value for  High TCI EBV stock only to find two weeks after the auction the stock EBV’s that they purchased do not hold the same EBV value that they purchased.

In our opinion that is not good enough and it shows the AWA breed plan figures are way out in projecting even just a EBV  guide.

Furthermore other members conducting private camera evaluations on carcass marbling are showing figures that are inconsistent with the AWA breed plane figures.

The same goes for bulls that are producing camera evaluations on REA size, In Australia they have WORLD K’s SANJIROU.

As the No1 REA sire, with a EBV of 9.0 yet in the USA WORLD K’s SANJIROU is ranked 5th with BAR R SHIGESHIGETANI 30T Ranked No 1 miles ahead of WORLD K’s SANJIROU. (What figure do we believe?).

Breeders want consistency of sires that are evaluated whether is Australian EBV’s or American EBV’s or elsewhere.

The USA run on EPV’s and their system is based on purebred figures and Australian figures are meant to be based on full blood figures, or until the AWA are questioned and they say purebred figures are taken into account as well.

We totally dispute mixing purebred figures with full blood resulting in EBV’s given to animals.

They are and should be in two different registers as the figures are distorted with Purebred Wagyu as they are infused with a greater degree of hybrid vigor in their genetic makeup.

The Wagyu herd book should be divided into the following sections:

  1. A class 100% Full blood Wagyu (Black and Red Wagyu)
  2. B class 93% to 99% Purebred Wagyu (with breeders reaching 99% to get Full blood registration)
  3. B+ class 93% to 99% Purebred Wagyu (to include Polled Purebred Wagyu)
  4. C Class 75% to 92% Purebred Wagyu (with breeders reaching 75% to get Purebred registration)
  5. D Class 50% 50% Cross bred Wagyu (with breeders reaching 75% to get Purebred registration)
  6. E Class Polled Wagyu Homozygous and Heterozygous registers.

All animals registered have the fields already allocated when a breeders fills in registration forms.
