Genetics R&D: A bull selection decision support tool

Summary

Genetic information is multifaceted, complex confusing and time consuming to assess (i.e. multiple estimated breeding values and selection indexes). The tools that are currently available need to be simplified and implemented with user friendly interfaces in order to re-start the conversation on the production benefits of genetic improvement.

The aim of this project was to use information from the national beef recording and improvement scheme (BREEDPLAN and BreedObject) to develop a decision support tool, which is easy to use and simplifies the bull selection process for commercial beef producers.

DeSireBull^TM was developed using existing genetic tools (e.g. BREEDPLAN) and relies on BreedObject bio-economic models to rank bulls based on genetic merit. It provides an online platform for bull vendors to list their sale catalogues containing all relevant genetic information for their bulls as well as images, videos and other supplementary pre-sale information.

Objectives

The main objectives of this project were to:

• increase effective use of genetic merit information by producers
• increase market signals reaching bull breeders from commercial producers, using genetic merit information of their bulls
• continued effective use of BREEDPLAN 
• create a more transparent beef genetic marketplace where genetic information plays a greater role
• create ann increased demand for bulls with good genetic merit for economically important traits
• create an easy to use, accessible decision support tool.

Key findings

• DeSireBull^TM is easy to use and allows commercial producers to place emphasis on particular groups of traits, using a behind-the scenes algorithm to demonstrate the consequences of a desired gains approach to selection decisions.
• The tool enables commercial bull buyers to source the most appropriate bulls for genetic improvement of their herd. 
• It is envisaged that the tool will enable more informed selection decisions and that these decisions will lead to greater productivity and profitability for commercial enterprises.
• The tool also provides a feedback mechanism to seedstock producers. It is envisaged that this feedback mechanism will inform seedstock producers of their most "valuable" animal based on the genetic merit of the animals and help to inform future breeding decisions to supply bulls matching market demand.

Benefits to industry

It is anticipated that the tool will allow some flexibility in commercial producers' selection decisions without completely compromising genetic gain. As a result, the rate of genetic gain in the commercial sector as well as the entire beef industry is expected to lift, aiding the NLGC's aim to double the rate of genetic gain by 2020.

As a result of improved rates of genetic gain, it is expected that producers will witness an increase in the productivity of their herds and be rewarded with increased profitability.

MLA action

MLA is currently working with other partners to commercialise the tool.

Future research

 Options for the commercialisation of this tool include:

• domestically through existing genetic evaluation/information providers
• internationally by selling the tool's framework to overseas genetic evaluation/ information providers (e.g. IGS)
• allowing the tool to be more flexible in its data requirements (i.e. allowing breed societies on earlier versions of selection indexes the ability to use the tool).
