Stakeholder perceptions of thoroughbred yearling sales endoscopy in Australia: can we do better?

ABSTRACT

OBJECTIVE: To identify thoroughbred industry stakeholders' views on the yearling sales endoscopy in Australia. DESIGN: Semi-structured qualitative group interviews with equine veterinarians, thoroughbred breeders and yearling purchasers. METHODS: Twenty-nine experienced thoroughbred industry stakeholders participated in online focus groups (1) equine veterinarians involved in yearling endoscopy; (2) thoroughbred breeders; and (3) yearling buyers. The focus groups were audio and video recorded and digital whiteboards were available. Data was transcribed, live-coded and analysed thematically. RESULTS: The main themes identified included the uncertainty surrounding the relationship between yearling laryngeal function and future performance, especially the significance of yearlings with grade 3 out of 5 laryngeal function; interobserver variability in the laryngeal function grade assigned by veterinarians to the same endoscopic exam; and the presence of intra-horse variability in laryngeal function over different time points. DISCUSSION: Stakeholders raised multiple concerns about the current yearling sales endoscopy process in Australia. Recommendations to address these concerns include further investigation into the race performance of yearlings identified with grade 3 laryngeal function; training of veterinarians to reduce inter-observer variability; and the need to determine the most appropriate grading system to use in yearlings. Future research should evaluate the significance of intra-horse variability in a yearling population.
