The Use of Platelet-Rich Plasma in Wildlife Veterinary Medicine

Abstract

Platelet-rich plasma (PRP), an autologous blood product concentrated with platelets and their associated growth factors, has been the subject of increasing investigation in veterinary medicine. Although it is widely used in domestic species, its use in wildlife is less well-explored, despite its potential to address complicated clinical scenarios such as traumatic injuries, chronic wounds, and orthopaedic conditions, which are frequently encountered in wild animals under human care. Expanding the evidence base for PRP in non-domestic species could therefore significantly advance clinical outcomes in rehabilitation, zoo medicine, and conservation initiatives. The aim of this scoping review was to identify and describe the existing evidence on the clinical use of PRP in wildlife. This included details on protocols, outcomes, species-specific considerations, and knowledge that is still missing. A literature search was performed using the databases PubMed, Scopus, Web of Science, and Google Scholar up to August 2025. Studies were eligible for inclusion if they reported on the preparation, application, or clinical outcomes of PRP in non-domestic animal species. This included case reports, research articles, and reviews. A total of 65 studies were finally included. The data were classified by species group (e.g., reptiles, birds, mammals) and clinical application (e.g., wound healing, orthopaedics, chronic disease management). The search identified a limited but growing body of evidence, primarily consisting of case reports and small-scale experimental studies. The application of PRP was found to have beneficial effects on wound closure, inflammation reduction, and enhanced tissue regeneration across multiple taxa. However, substantial variation existed across protocols in platelet concentration, activation methods, and application routes across protocols. Species-specific challenges, such as limited blood volume and logistical constraints in wildlife settings, were frequently noted. Current evidence suggests that PRP is a promising therapeutic tool in wildlife medicine; however, the development of standardised methodologies and the implementation of controlled clinical trials remain urgently needed. Widening its use could not only enhance animal welfare but also reinforce conservation initiatives and advance One Health strategies by generating insights with direct relevance to human medicine.
