You Define the Objective. MateSel Delivers the Best Possible Outcome.

When it comes to breeding decisions, every mating shapes the future of your herd.

MateSel is a powerful software tool designed to help Wagyu breeders utilise available genetics in line with their breeding objectives, enabling more informed, effective and profitable mating decisions. By combining pedigree information, Wagyu Breeding Values (WBVs) and $Index values, MateSel evaluates all possible mating combinations to generate optimised mating allocations and backup mating plans using your nominated sires and dams.

Whether your objective is to increase marbling, improve carcase performance, maintain fertility, manage inbreeding or target a specific $Index, MateSel helps identify the mating strategy most likely to achieve your desired outcome.

Why Use MateSel?

Unlike traditional mating planning tools, MateSel evaluates every possible mating combination against your defined breeding objectives and constraints to identify the most suitable pairings across the entire herd.

Rather than simply selecting the highest-performing animals, MateSel applies advanced genetic evaluation technologies to balance genetic gain with sustainable breeding practices, helping breeders maintain future breeding flexibility while achieving continuous whole-herd improvement.

The result is a data-driven mating plan that removes much of the guesswork from breeding decisions and provides greater confidence in the genetic direction of your herd.

Addressing Wagyu Breeding Challenges

Wagyu breeders face a unique set of challenges. The breed’s global reputation is built on exceptional marbling, eating quality and carcase performance, while genetic diversity must be carefully managed within a relatively narrow gene pool.

MateSel helps breeders address these challenges by:

  • Maximising genetic gain in economically important traits such as marbling, carcase weight and eating quality
  • Maintaining genetic diversity and reducing the risk of inbreeding depression
  • Supporting targeted breeding strategies, such as improving fertility while maintaining carcase performance
  • Integrating pedigree information, genomic testing results, WBVs and $Indexes to deliver robust, evidence-based recommendations
  • Managing long-term relatedness within a herd by limiting the overuse of heavily utilised sires

By balancing genetic progress with diversity, MateSel supports sustainable genetic improvement across generations.

Practical Benefits for Breeders

Beyond genetic optimisation, MateSel provides practical support for day-to-day breeding and management decisions.

The program can help breeders:

  • Select the most appropriate sires for their breeding objectives
  • Determine semen straw requirements for AI programs
  • Identify and allocate backup sires
  • Optimise natural mating groups
  • Plan joining programs more effectively
  • Prioritise cows and heifers for joining, retention or culling
  • Improve utilisation of available genetics across the herd

These practical outputs ensure mating recommendations are not only genetically sound but also workable within real-world breeding systems.

You Stay in Control

One of MateSel’s greatest strengths is that breeders remain firmly in control of the breeding direction.

Breeders define the objectives, priorities and constraints that matter most to their operation, whether that means targeting a specific $Index, improving particular traits, managing inbreeding levels or preserving genetic diversity.

MateSel then evaluates all available mating combinations against those requirements and delivers the optimal outcome to help achieve those goals.

Simply put: You define the objective. MateSel delivers the best possible outcome.

IMPORTANT NOTICE - Terms & Conditions


It is a condition of use of this database that you accept these terms and conditions. 

It is important that you appreciate when accessing the Australian Wagyu Association Limited (AWA) database (which may be hosted on an external website) that the information contained on the AWA database, including but not limited to pedigree, DNA information, Wagyu Breeding Values (WBVs) and Index values (together called Database Information), is based on data supplied by AWA members and/or third parties. 

Whilst sincere effort is made to ensure the Database Information is accurate and complete, to the extent permitted by law, AWA, its officers and employees, shall not be responsible for its use or interpretation, and you use the Database Information at your own risk. Please be aware of the following limitations of the Database Information.  

Regarding WBVs and Index values, it is important to appreciate, and you need to be aware that: 

  • WBVs are derived using genetic evaluation technology developed for the AWA, using information contained within the AWA database and parameters derived from it.
  • WBVs are estimates of genetic potential of individual animals and may change with addition of new data or with new parameters.
  • WBVs are genetic merit estimates only and may not reflect the raw animal phenotype.
  • WBVs can only be directly compared to other WBVs calculated in the same AWA genetic analysis.

Regarding pedigree and DNA testing results submitted to the AWA, it is important to appreciate, and you need to be aware that: 

  • Animals whose registration identifiers start with PED are Pedigree Recorded Animals. What this means is that the details which AWA used to register the animal were obtained from a Recognised Wagyu Registry Organisation – in other words a Wagyu breed association based outside of Australia. AWA has not independently verified the information with respect to the animal or the details recorded about the animal. You should read AWA’s by-laws which set out details regarding the definition of a Pedigree Recorded Animal. 
  • Pedigree and DNA data submitted and supplied to AWA may have errors in it which cannot be detected without further DNA testing. 
  • Technology may have advanced since a particular test was undertaken so that genetic issues or inaccuracies which were previously not detectable are now able to be detected by current testing technology (i.e. if the animal was tested again with current technology). 
  • AWA estimates that less than 1% of the pedigree entries, ownership or breeding details in the AWA Herdbook may have errors or which may be misleading. For this reason, users ought to consider if they need to obtain independent testing of the relevant animal (if possible) to ensure that the data is accurate. 

Regarding prefectural content, it is important to appreciate, and you need to be aware that: 

  • Prefectural content is based on the estimation of prefectural origin from Japanese breeding records of 201 foundation sires and 168 foundation dams. As genotype-based parent verification is not used in Japan, and full Japanese registration certificates are not available for all foundation animals, exact prefectural composition for these sires and dams cannot be validated. 
  • The calculation of prefectural content for Australian Herdbook animals relies on the accuracy of pedigree records and DNA samples provided by AWA members.   

Regarding DNA testing and genetic condition results submitted to the AWA, it is important to appreciate, and you need to be aware that: 

  • As genetic testing results are provided by independent DNA testing laboratories at the request of AWA members, AWA relies solely on the accuracy of the reporting of genetic testing as completed by the laboratories. 
  • AWA uses GeneProb software to calculate the likelihood of pedigree animals being a carrier of genetic conditions.  This likelihood is an estimate based on the available genetic testing results. 

If you consider that you do not understand or appreciate the nature and/or implications of the data provided on this website or the WBVs of a particular animal, then AWA strongly recommends that you seek expert advice.  Note there is substantial technical information and articles on the Wagyu website to assist our members. 

AWA’s liability for any loss or damage, consequential or otherwise, suffered or incurred by you or your related business, arising directly or indirectly from your use of Database Information, to the extent permitted by law, is limited to AWA providing you with a refund for the fees paid for the service (if any), or AWA re-performing the service, where possible, at the election of AWA.  

AWA administers this database in good faith to support AWA members and the industry. AWA does not represent or warrant that the animals recorded in this database, or animals breed from them, will achieve any particular genetic or phenotype performance.
