Radiographic findings of candidate stallions presented for licensing at all German Warmblood horse-breeding associations in 2018--2020

preprint OA: closed

Abstract

Background: Current studies on the health status of young German Warmblood stallions, which will probably shape future equestrian sport and horse-breeding, are lacking. Objectives: To evaluate the prevalences of radiographic findings at licensing examinations of Warmblood candidate stallions and quantify the influences of season of birth, age at licensing, year of licensing, and the evaluator on the distribution of recorded findings. Study design: Retrospective observational study. Methods: : The records of 1693 radiographic examinations performed on 1678 German Warmblood stallions presented for licensing in 2018–2020 were reviewed. Data were provided by all German Warmblood horse-breeding associations and their official veterinarians. The collection and storage of the records were performed using the German equine health database. The influences of environmental effects (season of birth, age at licensing, year of licensing, evaluator) on main radiographic findings were determined using generalised linear models with a significance level of p < 0.05. Results: : Overall, 71.4 % of the candidate stallions had remarks in their radiographic examinations protocols. However, the majority of the respective stallions had only single (49.8 %) or two (34.4 %) radiological findings. Main regions of the recorded findings were the proximal phalanx including the fetlock joint (25.3 %), the cannon bone (20.3 %), the navicular bone (17.2 %), and the hock (17.2 %). Specifically, radiopaque bodies in the fetlock joint, contour changes of the proximal phalanx and cannon bone, and changes of the navicular synovial invaginations were documented. The distributions of several radiographic findings differed significantly between evaluators. Main limitations: Homogenous study population and retrospective data. Conclusion: The majority of German Warmblood candidate stallions presented for licensing in 2018–2020 had radiographic findings recorded. The clinical relevance of several of these findings in clinically healthy horses remains uncertain. Follow-up evaluations could contribute to better risk assessment and are, therefore, recommended.
