Equine Health Studies Program 2014 Equine Research Report Scientific studies conducted to help advance equine health and well-being LETTER FROM OUR DEAN The LSU School of Veterinary Medicine (LSU SVM ) is pleased to once again present the Equine Health Studies Program (EHSP) Equine Research Report, which covers scientific and scholarly activities of the program from 2011 through 2013. The EHSP continues to focus on the health, well-being and performance of horses by delivering state-of-the-art research and clinical services that benefit the horse- owning public. As a former equine surgeon and faculty member, I have watched the EHSP grow and flourish, as evidenced by the contents of this research report. Since its inception in 2005, the EHSP has been translating research into practical solutions for our broad-based constituents and clients in addition to delivering clinical services, education and community outreach to referring veterinarians and clients. The EHSP continues to make significant contributions to our understanding of the complex mechanisms of horses in health and disease. The EHSP collaborates with other universities, industry and foundations to discover new treatment and preventative measures for lameness, gastrointestinal disease, endocrine disease and respiratory disease, which collectively result in a significant yearly loss of revenue to the equine industry. More specifically, EHSP faculty scientists are actively studying a number of common diseases, including osteoarthritis, laminitis, long bone fracture repair, gastric and colonic ulcer disease, Equine Cushing’s disease, and inflammatory and allergic airway disease (summer pasture associated obstructive pulmonary disease). The EHSP continues to build and maintain strong relationships and community engagements with Louisiana stakeholders so that it can respond to the needs of horses and horse owners. In the aftermath of Hurricane Isaac, the EHSP and the LSU SVM, in concert with the Louisiana State Animal Response Team, were able to help horses and other large animals in need by supplying personnel for search and rescue, triage of injured animals, and clinical and surgical care. The EHSP has been and continues to be on-alert to respond to the needs of horses and is a model for emergency preparedness for other veterinary institutions. Additionally, the EHSP continues to provide strong leadership and the latest information to horse owners through its continued involvement with referring veterinarians, the Louisiana State Racing Commission, the Louisiana Equine Council, the Louisiana Thoroughbred Breeders Association, the Louisiana Horse Rescue Association and many others. In closing—just a few comments as I get ready to ride off into the sunset after nearly 40 years in the saddle here at the LSU SVM—my engagement in developing our large animal clinic, as well as my tour as an administrator, have been most rewarding, both personally and professionally. In the final analysis, it’s always about the people, and our programs here have been blessed by many strong relationships with the equine community. I could not be more proud of the emergence and productivity of our EHSP as it continue to benefit horses throughout the world. I am always humbled by the dedication of our faculty and staff and their continued commitment to the mission of the EHSP and the LSU SVM. I have truly appreciated everyone’s support and know that the EHSP will continue to bring national and international recognition to the School. My best personal regards, Peter F. Haynes, DVM, DACVS, Dean 2 LETTER FROM OUR INTERIM ASSOCIATE DEAN FOR RESEARCH AND ADVANCED STUDIES The LSU School of Veterinary Medicine continues to promote a high level of support for equine health through teaching, research and service. The equine industry is an integral part of the Louisiana livestock community, especially the racing industry. Our Equine Health Studies Program is the basis for the research effort that investigates and provides up-to-date and pertinent information for educating students and extending service to the public. It is important for our faculty to continue building through extra-mural support, and we have been fortunate to have a number of sources that include federal (National Institutes of Health, USDA), state (equine health appropriation) and private/industry (Grayson Jockey Club Research Foundation, Elanco, Boehringer Ingelheim Vetmedica, Zinpro Corporation, Centaur Corporation, Seabuck Equine, SmartPill Corporation, Pall Corporation) funding. The faculty contributing to the program are to be commended for their concerted efforts to ensure that equine health remains one of the top priorities of the LSU SVM. Sincerely, James E. Miller, DVM, MPVM, PhD Interim Associate Dean for Research and Advanced Studies Professor of Epidemiology and Community Health Veterinary Teaching Hospital Equine Clinic Providing comprehensive, advanced medical, surgical and reproductive care for horses Services include lameness and performance evaluation (including a high speed treadmill), advanced diagnostic imaging (MRI, CT, ultrasound, radiology), dynamic endoscope, emergency and critical care, mare and stallion fertility, internal medicine, laparoscopic and arthroscopic surgery, laser surgery, and integrative medicine (acupuncture and massage and shock wave therapy).

As director of the program, I am honored to present this research report documenting the productive faculty here at the LSU SVM. The EHSP team remains committed to the health, well-being and performance of horses through veterinary research, education and clinic and public service (our mission). As you can see from the contents of this report, dedicated faculty and staff continue to provide high quality biomedical research to address the health needs of horses. I congratulate each and everyone in the program for their continued commitment and devotion to excellence. The EHSP biomedical research team has diverse research interests with one major goal: to improve the health and welfare of the horse. Investigators represented in this report contributed important information in the areas of disaster response, gastrointestinal disease, laminitis, dermatology, diagnostic imaging, reproduction, respiratory physiology and disease and surgery. Each study in this report highlights benefits to the horse and the equine industry. Many of these research findings were presented at national and international meetings, including the American Association of Equine Practitioners, the American College of Veterinary Surgery, the American College of Veterinary Internal Medicine, the Veterinary Orthopedic Society, the Laminitis Society, the Applied Equine Nutrition and Training Conference, the Brazilian Association of Equine Practitioners and the American Society of Animal Science. EHSP researchers continue to be sought-after speakers at major conferences throughout the region and the world. The biomedical research outlined in this report and state-of-the-art facilities on campus are a direct result of support from the Louisiana Governor’s Biotechnology Initiative Grants Program, Louisiana Board of Regents Enhancement Grants Program and recurrent funding through the State Legislature resulting from Louisiana racetrack slot machine revenue. Also, funding for many of these important projects was provided from extramural sources, including the Grayson Jockey Club Research Foundation, the Morris Animal Foundation, the Merial-NIH Veterinary Student Summer Scholars Program, Boehringer- Ingelheim Vetmedica, Elanco Animal Health, the Pennington Biomedical Research Foundation, the National Wetlands Research Center, the National Institutes of Health, SmartPak®, Zinpro Corporation and Purina, among others. Furthermore, we owe our deepest gratitude to the horses that participate in these studies. The research findings presented in this report would not have been possible without the availability and use of horses. All biomedical research on animals at LSU is conducted under Federal Guidelines for the Humane Care and Use of Animals and approved by the Institutional Animal Care and Use 4 LSU SCHOOL OF VETERINARY MEDICINE Committee within the LSU SVM. Horses were carefully and compassionately used for the advancement of ADMINISTRATION equine health to discover more effective methods to diagnose, treat and prevent illness and injuries. These Peter F. Haynes, DVM, DACVS Dean horses are valued members of our program and are treated with kindness and dignity. In some cases, James E.
