AgriFutures Thoroughbred Horses Program Request for Quotation: Endoscopy in yearlings prior to sale

This Request for Quotation (RFQ) is seeking services of an individual or organisation to undertake a body of work to provide AgriFutures Australia with an understanding of laryngeal movement examinations of young unbroken thoroughbred horses and if it is a reliable indicator of future race performance.

It is anticipated that the project should consult with industry experts as well as conduct a retrospective study on endoscopy images of the upper respiratory tract, with particular focus on the laryngeal/pharyngeal regions, and the relationship to race performance, completed on young sale horses as part of the AgriFutures Australia Thoroughbred Horses Program.

Individuals or organisations making a submission are required to understand the thoroughbred horse industry, veterinary aspects associated with yearling sales, and preparation and sale of yearlings.

This RFQ closes 12 noon AEDT, Wednesday, 10 February 2021


Endoscopic imaging of the upper respiratory track of yearling thoroughbreds is currently required for commercial sale and is considered a predictor of future race performance of thoroughbred horses. Limited information in Australia on endoscopic imaging, however, raises questions about the value of this measure and its accuracy in predicting performance.

This much needed research will help dispel, or confirm, myths around the future racing abilities of young horses with certain grades of laryngeal function. It will inform industry discussions around the relevance of endoscopic findings on the upper respiratory tract of yearlings as a requirement of commercial sale.

Project requirements

Preliminary discussions with industry expert veterinarians have identified the following points to be considered by this research:

  • What do we know about the relationship between laryngeal movements and race performance? There have been previous studies performed in Australia, UK and USA but care must be taken interpreting these, as there are differences in the grading systems for laryngeal function between countries.
  • How do the current grading systems relate to laryngeal disease/dysfunction and the rate of progression of the disease/dysfunction? This may help dispel or confirm myths around the future racing abilities of young horses with particular grades of laryngeal function.
  • Previous international research has shown that when comparing race outcomes, there is no difference between grade one & two horses, to grade three horses, but this work is not universally accepted. A pass/fail grading instead of the current grading system should be considered by the researcher.
  • This research will help to understand if the examination of the laryngeal movements of young, unbroken horses is a reliable indicator of future race performance.

Project deliverables

This study will help understand if the examination of laryngeal movements of young, unbroken thoroughbred horses at rest is a reliable indicator of future race performance.

The successful individual or organisation is expected to address the following:

  • Use endoscopy images of horses from the 2014 to 2018 Classic, Magic Millions, Easter and Melbourne yearling sales.
  • A total number of 4000 to 5000 images should be used
  • Summarise expert opinion on findings and importance of endoscopic imaging of yearlings.
  • Conduct a retrospective study of endoscopy images completed on young horses from the above noted sales and dates and subsequent racing performance.
  • Compare findings to international literature of radiography in young thoroughbreds.
  • Present findings to the Thoroughbred Horses Advisory Panel and industry meetings, where appropriate.
