The entire Australian beef industry is seeing near-record prices at the moment, and Wagyu beef continues to hold its position as the premium breed of cattle. It is incredibly pleasing to celebrate the success of the Wagyu Sector and see it continue to go from strength to strength.
FINDINGS OF THE 2021 POGSON AWA GOVERNANCE REPORT
test results were positive, and we look forward to seeing calves hit the ground and the first rounds of data being collected. Cohort 2 sire intake has been completed, with 32 sires to be used within the 2022-2023 breeding program. These sires will be reviewed through the AWA-PTP Consultative committee prior to their final acceptance into the program.

Dr. MATTHEW McDONAGH
WAGYU SECTOR GROWING RAPIDLY Dear Members, As we come out of COVID-19 restrictions, we are looking forward to being able to catch up with each other under more normal circumstances. We are getting good interest from our International Members in returning to Australia to take part in the 2022 WagyuEdge Conference. I look forward to greeting many of you at the 2022 Conference. It has been a very busy year since our last major event and the Wagyu Sector is growing rapidly. Many of our speakers will touch on the opportunities that come with growth, along with the need for strategic planning on how to manage our evolving operating environment.
AWA BOARD UPDATE (22 FEBRUARY 2022 MEETING) The AWA Board has met for review of the AWA half yearly (July to December) performance against the 2021-2022 operational plan, assess statutory items and consider key items as follows: 1. The WagyuEdge 2022 Annual Conference program was confirmed for 26 April – 28 April 2022 in Melbourne Victoria. It will be a condensed 2.5 day Conference with a technical session on the afternoon of the 26 April prior to a Welcome Function that evening. We then have 2 full days of high-quality research, technical and industry speakers with the Elite Wagyu Sale and Cocktail evening on the 27 April and the conference concluding with the AWA Gala Dinner and WBBC awards on the evening of the 28 April. Currently, Victorian COVID-19 guidelines require all attendees to have current vaccination certificates. 2. Updated Wagyu genetic parameters within Wagyu BREEDPLAN model were approved. The Board reviewed research conducted by the Animal Genetics and Breeding Unit regarding the genetic parameters used within the BREEDPLAN model and approved updating these to use the latest and best genetic estimates for the Wagyu population. The updated parameters provide increased range in EBVs for core traits and improvements in EBV accuracy. These changes were implemented 7 March 2022 and presented in Wagyu Webinar #12. 8
THE AUSTRALIAN WAGYU UPDATE - ISSUE 80
3. Change of the Wagyu BREEDPLAN model to include crossbred Wagyu carcase data was approved. The Board reviewed research conducted by the Animal Genetics and Breeding Unit and the Agricultural Business Research Unit and the University of New England regarding the a new BREEDPLAN model that enabled incorporation of data from crossbred Wagyu animals into BREEDPLAN. This was approved to enable crossbred data to improve the estimate of EBVs and accuracy calculations within Wagyu BREEDPLAN. This enables an enormous increase in the amount of data available to be used in Wagyu BREEDPLAN for the benefit of members. These changes were implemented 7 March 2022 and presented in Wagyu Webinar #12.

4. The Board response to the November 2021 Report by Mr Philip Pogson on AWA governance was approved. As previously reported (November 2021), the AWA Board commissioned an independent review of its corporate governance policies, procedures in September 2021. Mr Philip Pogson (the Leading Partnership) was commissioned and provided his final report in November 2021. My Pogson provided 16 recommendations for action by the AWA. The AWA Board has accepted all 16 recommendations and will respond to these within 2022. 5. Core services pricing review. A review of AWA pricing of services to members was completed over the 2017 – 2021 period. As presented to AWA members in Wagyu Webinar #8 2021 AWA Financial Update July 2021, the AWA has decreased its cost of services to members by 11% since 2017. The Board noted that CPI has increased by 10.5% over the same period, with annual net profit retained by the AWA decreasing to 3%. The Board approved increasing AWA core services by 5% at 01 July 2022, with annual CPI increases thereafter on an annual basis. WWW.WAGYU.ORG.AU SALES-EVENTS > WEBINARS
6. Company operational performance against KPIs to the end of second quarter FY2022 was reviewed, with progress to date satisfactory against all key work areas. Financial performance was reviewed, noting satisfactory operation against budget year to date.

CROSSBRED DATA NOW USED IN WAGYU BREEDPLAN CROSSBREEDING - A MAJOR COMPONENT OF AUSTRALIAN WAGYU SECTOR PRODUCTION The Australian Wagyu Association estimates that historically, up to 80% of Australian Wagyucontent branded production has been derived from F1 animals, although recent production trends have seen a shift towards increased slaughter numbers of fullblood, purebred and high Wagyu content (F2 and F3) cattle.
The Australian Wagyu Sector has emerged over the past 20 years to be a very significant component of the Australian beef industry. Unique high marbling (Marble Score 6 through to 9+) along with marbling fineness, high unsaturated fats and exceptional eating quality, has differentiated Wagyu beef from that of other breeds. Many of these attributes also have very significant benefits for crossbred Wagyu carcase production. The remarkable quality difference between Wagyu beef and that of other breeds is exemplified in F1 Wagyu beef, where fullblood Wagyu sires are crossed with females of other breeds (primarily Angus). F1 Wagyu product gains significant quality improvements from fullblood Wagyu sire genetics when used across appropriate maternal breeds, with marble score averages for F1 Wagyu (approximately MB 5.5) sitting halfway between fullblood averages and long-fed averages of other breeds. Crossbreeding with Wagyu genetics provides an instant mechanism to increase the volume of production of high-grade carcases, with fullblood Wagyu sires used

in terminal crossing to generate large numbers of slaughter cattle to meet expanding domestic and international markets for high-value Wagyu content product. One of the ways the AWA supports the Wagyu Sector, is by combining large volumes of pedigree, genomic and performance data into the Wagyu BREEDPLAN genetic analysis to enable estimation of breeding values for Wagyu sires and dams. As shown in Figure 1, of the article Major improvements to AWA Wagyu BREEDPLAN on page 31, AWA has seen rapid increases in the volume of fullblood carcase data submitted to support Wagyu BREEDPLAN over the last 5 years. This data is vital to improving the EBV accuracy of production traits across the whole registered Wagyu population. To date, Wagyu BREEDPLAN has only used data from fullblood and purebred progeny to determine the genetic merit of sires and dams for several growth and carcase production traits. The number of crossbred Wagyu progeny of fullblood sires that are slaughtered each year exceeds the total volume of fullblood and purebred production by many folds. This data is a potential source of new information to improve Wagyu BREEDPLAN, particularly the large volumes of F1 and higher content carcase data that can be accessed by members through their supply chain relationships.

Researchers at the Animal Genetics and Breeding Unit (AGBU) have completed evaluating the inclusion of crossbred carcase data from this project in the Wagyu BREEDPLAN analysis. Data from approximately 8,000 individual crossbred animals was included in trial runs of the Wagyu BREEDPLAN analysis to assess the impacts of using crossbred data along with fullblood data on the calculation of EBVs. To include crossbred information in the routine Wagyu BREEDPLAN evaluation, the analysis model was expanded to account for heterosis effects of varied maternal breeds and calves.

Crossbred data now used in Wagyu BREEDPLAN
These large increases in average EBV accuracy for these sires reflects that many sires had very low accuracy EBVs prior to addition of the new crossbred carcase progeny data (some were well below 50% accuracy). The large change in accuracy reflects that significant new progeny records for these sires have benefited the ability to estimate the EBVs for these sires.

Don’t let pestivirus rob you blind Pestivirus is an insidious cattle disease. It can take from you before you know it. It causes significant reproductive and performance issues, and weakens immune systems - leading to other costly cattle health problems like respiratory disease. In fact it costs the industry over $114m every year.[1] To protect your herd from pestivirus and optimise your returns, it pays to be on Pestigard.

Crossbred data now used in Wagyu BREEDPLAN
... the use of large numbers of crossbred Wagyu progeny data for the four example Foundation sires provides a very consistent and reliable outcome for the CWt and MS EBVs.
<<< from page 23 The simple comparison between the old and new EBVs for the Foundation sires in Figures 4 and 5 demonstrates that the use of large numbers of crossbred Wagyu progeny data for the four example Foundation sires (926 new records in total), provides a very consistent and reliable outcome for the CWt and MS EBVs. Using crossbred data in Wagyu BREEDPLAN resulted in no significant changes in the CWt and MS EBVs of these Foundation sires. This is a result of both the EBVs for these sires already being highly accurate, and the input of crossbred Wagyu carcase progeny data
SUMMARY AND FINDINGS The Wagyu BREEDPLAN genetic analysis model was last updated in 2018 by the independent research group – the Animal Genetics and Breeding Unit (AGBU) based at the University of New England. This update enabled inclusion of crossbred genomic DNA data for the Wagyu BREEDPLAN analysis. The AGBU have now completed an update of the Wagyu BREEDPLAN genetic analysis model so that data from crossbred animals can now be used to support the calculation of EBVs. This will enable thousands of carcase progeny records from crossbred Wagyu to be used in Wagyu BREEDPLAN to improve EBVs of

BREEDPLAN article on page 31, one primary function of the Wagyu BREEDPLAN genetic analysis is to separate the proportion of trait performance that can be attributed to genetics To allow this, Wagyu BREEDPLAN analyses how progeny performance from sires and dams compares within management groups (contemporary groups), so that relative genetic merit can be estimated for each animal. Genomic information further defines the genetic influence and in conjunction with recorded

pedigrees the relatedness of animals. Now that Wagyu BREEDPLAN can accommodate data from crossbred Wagyu animals (F1 and higher content progeny: crossbred data now used in Wagyu BREEDPLAN article on page 15, it is essential that members plan and manage appropriate groups of animals if they wish to use crossbred data to contribute to the EBVs of their sires. Unlike fullblood progeny data, which provides information to support sires and dams, using crossbred F1 progeny data only provides performance information to support the Herdbook registered sire of the crossbred progeny. As higher-grade data (F2 and F3) is provided, BREEDPLAN will also attribute genetic information to other known parents and grandparents. ISSUE 80 - THE AUSTRALIAN WAGYU UPDATE
27
TIPS FOR PLANNING AND RECORDING KEY INFORMATION TO GET THE MOST OUT OF YOUR CROSSBRED DATA
1. ONLY USE REGISTERED SIRES This seems like an obvious point, but to use crossbred data to prove EBVs for your sire, the sire must be registered with the Australian Wagyu Association. You also need to make sure other sires whose progeny you wish to compare to, are also registered with the AWA so that a valid comparison can be made.
2. USE MORE THAN ONE SIRE A key purpose of Wagyu BREEDPLAN is to use progeny performance data to determine genetic differences between sires. If you only have data from the progeny of one sire within a group, that data cannot be compared to the progeny of another sire. The use of only one sire is called a single-sire contemporary group and the data is of no value for analysis of genetic differences between sires. For this reason, BREEDPLAN requires that at least two sires be represented in each contemporary group if the performance of the progeny is to be compared and used to determine the genetic potential of each of the sires and to calculate their EBVs. This can be achieved through mating two sires naturally or using artificial insemination programs with a natural “back-up’ sire. Where AI is used, it is recommended that the back-up sire/s are put in with the females shortly after AI (within 21 days) so that all calves are born within a certain period and can be considered in one contemporary group. Calves will only be considered as one contemporary group if they are born within 45 or 60 days of one another.
3. RECORD BIRTH DATE Age is a key determinant of most traits, particularly weight traits and carcase traits. So that BREEDPLAN can accurately account for age differences between animals within crossbred data sets, birth date must be accurately recorded. Slaughter data for F1 cattle cannot be used without a birth date record as age at slaughter is required.
4. DNA TEST YOUR CALVES Production of commercial (slaughter) Wagyu F1 and higher content cattle usually occurs in large management groups with multi-sire AI and/or natural joining programs. DNA testing is necessary to accurately ascribe the correct sire to each animal. The AWA will conduct parent verification on all crossbred Wagyu slaughter progeny. Genomic SNP testing for parentage is recommended.
5. KEEP ANIMALS TOGETHER WHOLE-OF-LIFE Wherever possible, keep all progeny (of the same sex) together and manage them the same. This ensures that all progeny have been given an equal opportunity to perform and can be directly compared within their contemporary groups. This is typical in most commercial production scenarios, where lots of animals are sold from a breeder to a buyer to make ‘pens’ within a feedlot and the whole pen is sent for slaughter on the same day.
6. SLAUGHTER DATE Only data from animals slaughtered at the same facility on the same day will be compared to each other in BREEDPLAN. There can be large variation in carcase trait performance between slaughter days and between slaughter facilities. Communicate with the feedlot that the animals are for BREEDPLAN analysis and request that they ensure all your animals are slaughtered on the same day in the same facility, where possible.

NEW WAGYU GENETIC PARAMETERS USED IN AUSTRALIAN WAGYU ASSOCIATION WAGYU BREEDPLAN
At the heart of Wagyu BREEDPLAN is a statistical model that uses all the supplied data to calculate the best statistical estimate of the genetic merit of animals for the reportable Wagyu traits. This statistical model uses “Genetic Parameters” which define the relative genetic contribution to each observable trait and the relationships between traits. For any Wagyu production trait (eg. Birth Weight), there is a proportion of an animal’s phenotype (observed birth weight) that is a result of its genetics (heritability – how much of the trait is heritable) and a proportion that is due to the environment (non-genetic – how much the trait is influenced by the environment). The maternal nutrition available to the foetus during gestation i.e. the non-genetic effect, accounts for more than 50% of the ultimate Birth Weight of the calf with the other proportion being attributed to genetics. As with Birth Weight, other weight/growth traits are also partly determined by genetics (heritabilities of about 30-40%) and these traits tend to be related to each other. For instance, if an animal has a high 400 day weight (DWT), it tends to rank highly for 200 and 600 DWT as well. These relationships between traits are referred to as genetic correlations.
32
THE AUSTRALIAN WAGYU UPDATE - ISSUE 80
The Wagyu BREEDPLAN genetic parameters allow the calculation of EBVs from pedigree information, live animal performance, carcase data and genomic information provided by AWA members. These parameters are recalculated when a significant volume of new trait records are available to ensure they correctly reflect the trait heritability and the relationships between the traits.

The number of new records included more than 13,000 new records for carcase traits and 20,000 records for growth traits. As shown in Figure 1, the Wagyu BREEDPLAN Genetic Parameters were last updated in 2018 by the independent research group – the Animal Genetics and Breeding Unit (AGBU) based at the University of New England. This update was undertaken prior to implementation of Single Step Wagyu BREEDPLAN which enabled the use of genomic information in the Wagyu BREEDPLAN analysis. The AGBU undertake all research and development for BREEDPLAN.

A recalculation of the Wagyu Genetic Parameters in 2022 has included many thousands of new animal and carcase records across a significantly larger Wagyu data set
Genetic Parameters are scientific descriptors of the influence of genetics on each trait (how much variation in the trait is due to genes) and the relationships between traits (some traits are genetically linked to each other – like growth rate and carcase weight). Based on the large volume of additional data submitted between 2018 and 2022, the AGBU undertook the research work to deduct new genetic parameters. The AGBU have now completed a 2022 recalculation of the Wagyu Genetic Parameters which has included many thousands of new animal and carcase records across a significantly larger Wagyu data set. The 2022 Wagyu BREEDPLAN Genetic Parameters are significantly superior to the prior 2018 parameters and are now used within AWA Wagyu BREEDPLAN analyses commencing March 2022.

Of note in Table 1 is the increase in heritability of Carcase Eye Muscle Area (EMA) and Carcase Marble Score (CMAU). The new BREEDPLAN Genetic Parameters indicate significantly higher contributions from genetics on these traits. The analysis also determined there is now a higher amount of Genetic Variance than there was previously. This is important to Breeders, as the new BREEDPLAN analysis will result in more genetic range (EBV spread) within these traits to select animals from.

Major improvements to AWA Wagyu BREEDPLAN
SUMMARY AND FINDINGS The Wagyu BREEDPLAN Genetic Parameters were last updated in 2018 by the independent research group – the Animal Genetics and Breeding Unit (AGBU) based at the University of New England. The AGBU undertake all research and development for BREEDPLAN. The AGBU have now completed a 2022 recalculation of the Wagyu Genetic Parameters which has included many thousands of new animal and carcase records across a significantly larger Wagyu database. The impacts of changes to the genetic parameters within AWA Wagyu BREEDPLAN are consistent with those expected – a slightly larger range in genetic variance in those traits where higher heritability estimates are now calculated. These changes are advantageous for Wagyu breeders to make genetic progress when using EBVs in their herds. Within the March 2022 Wagyu BREEDPLAN analyses, the revised Wagyu Genetic Parameters as calculated by AGBU were applied. The new Genetic Parameters will continue to be applied to all future standard monthly Wagyu BREEDPLAN evaluations provided by the AWA to its members.

CONSTANT FOCUS ON IMPROVEMENT Given the elite status of Wagyu products, performance recording, genomic technologies and genetic analysis of Wagyu cattle is key to identifying and developing the best Wagyu genetics. The AWA delivers Wagyu BREEDPLAN, which produces Estimated Breeding Values (EBVs) for high-value traits in breeding animals. Wagyu breeders use EBVs in conjunction with other selection criteria when deciding which animals to mate in an attempt to breed superior progeny. Selections made using EBVs have driven the genetic progress made by the breed in recent years.

THE GOLD STANDARD BENCHMARKING PROGRAM FOR NEW WAGYU BREEDERS AWA 2021 - 2031 PROGENY TEST PROGRAM Within the current AWA genetic analysis, some individual Australian and International Wagyu sires have more than one hundred carcase progeny records. So far, AWA members have recorded significant numbers of carcase progeny data on approximately 250 Wagyu sires, making significant genetic gain in all carcase traits. However, data recording, particularly of carcase traits, can be difficult for smaller producers that do not operate a vertically integrated supply chain. The AWA-Progeny Test Program is specifically designed to bring the number of proven Wagyu sires to more than 500 sires whilst allowing smaller breeders to have their sires tested and all progeny data collected on a large scale program. The aim of the program is to add another 250 industry sires by mating up to 40 new sires per year from around the globe across 2,000 females. These will be benchmarked against each other as well as famous Japanese Foundation sire Michifuku (WKSFM0164) and his son Sanjiro (WKSFP0100).
By collecting progeny records from new sires and linking their performance and genetic data to existing data, the AWA hopes to identify new standout sires that will drive future genetic improvement for Wagyu.

incorporating 25 breeds. There are seven Wagyu animals in the top 25% most feed efficient cattle in the entire database of nearly 284,000 animals. The database includes phenotypic feed efficiency data on over 1,600 Wagyu bulls, heifers, and steers from five different sites around the world. Of the 1,600 cattle, 274 Wagyu heifers and bulls have been included in Vytelle’s multi-breed efficiency database to calculate expected breeding values (EBVs). The Wagyu NFI EBVs have moderate accuracies, up to 0.38, and range from -0.32 kg to 0.40 kg. Feed conversion ratios (FCR) of over 53,000 efficiency-tested cattle in Vytelle’s database shows that, on average, cattle consume 7.23 kg, on a dry matter basis, for every kilogram of gain. Selection for NFI in the breeding herd can significantly impact feed conversion and feed savings in the feedlot, especially for long-fed Wagyu programs. A 15% improvement in efficiency, which is highly probable when selecting for NFI, results in an average FCR of 6.15:1. When considering a feeding period of 450 days with feedlot entry and finishing weights of 300 kg and 725 kg, respectively; along with feed costs of $380/tonne as fed ($630/tonne of dry matter given a ration with a 60% dry matter content), a 15% improvement in efficiency will result in feed savings of $291.91/head. A 15% improvement in efficiency in the feedlot is significant, but further improvements are possible; 11% of the efficiency-tested cattle in the Vytelle database have FCRs below 5:1.

At Vytelle, we believe that genetic progress is the solution to this triple challenge, and one that can deliver permanent and compounding benefits.

highly in increased profit and reduced costs associated with feed resource savings without affecting size, growth, and performance traits. NFI savings remain constant through an animal’s lifetime without discernible effects on reproduction and efficient animals generate lower methane emissions. Ideally, all these benefits can be implemented by using Vytelle’s integrated technology platform to accelerate genetic progress—a permanent and compounding solution to the triple challenge facing the global agriculture industry.

Perfecting the production of quality Wagyu We have been investing in superior Wagyu Full Blood genetics to produce the most balanced Wagyu cattle outside of Japan. Flushing programs at Holbrook Veterinary Centre have been running for four years now, with progeny being integrated into Full Blood and F1 production. Our first cohort of progeny from our first progeny test program (in cooperation with QGI) are due to enter feedlots this winter. It is programs like this that importantly validate BREEDPLAN EBV’s. All genetics we invest in, now must be run through similar programs.
