Services
Equine Vaccinations
Customized vaccination schedules protect horses against infectious diseases. Our veterinarians develop tailored immunization plans considering travel patterns, competition requirements, and local disease risks. We administer core vaccines like tetanus and rabies alongside risk-based vaccinations for influenza and equine herpesvirus.
Digital Radiography
High-resolution digital imaging aids lameness diagnosis and dental evaluations. Our system provides immediate results with reduced radiation exposure compared to traditional film methods. Portable units allow on-farm diagnostics while maintaining image quality for precise treatment planning.
Lameness Services
Comprehensive lameness evaluations combine physical exams with advanced diagnostics. We utilize nerve blocks, motion analysis, and imaging technologies to identify subtle performance-limiting conditions. Treatment plans integrate regenerative therapies and customized rehabilitation protocols for equine athletes.
Swim Therapy
Our 60-foot therapy pool offers low-impact conditioning and recovery. Chlorinated water provides resistance training while minimizing joint stress. Staff-monitored sessions build cardiovascular fitness and muscle tone, particularly beneficial for post-surgical rehabilitation and neurological recovery cases.
Reproduction Services
Full-cycle reproductive care includes artificial insemination and embryo transfer. Our facilities handle cooled/frozen semen processing, mare fertility assessments, and foaling assistance. 24-hour monitoring ensures timely intervention during critical birthing periods using closed-circuit surveillance systems.
