Veterinary care for horses in rural areas is increasingly inadequate. Emergencies are often detected too late or reported unnecessarily due to a lack of systematic recording of genetic defects and health histories. Digital inventory management is rare because systems are often expensive, unreliable, lack internet access, and raise data protection concerns. Demographic change is exacerbating the situation. The project is developing a mobile app for digital patient records, which horse owners can use to record health and breeding data via a selection menu. The app integrates basic medical knowledge and supports the breeding management of endangered breeds through cross-population data analysis. It also connects digitally to the veterinary emergency service to identify emergencies more accurately. The aim is to establish a health database to prevent hereditary defects and health problems and to improve veterinary care in rural areas. Knowledge transfer will relieve the burden on horse owners and enable them to take charge of health care independently. The project includes practice monitoring and experimental studies for sustainable solutions and knowledge transfer.
