UK at the Equine Science Society Symposium

Several equine researchers from the University of Kentucky (UK) College of Agriculture attended the Equine Science Society (ESS) symposium May 31-June 3 in Murfreesboro, Tenn. The National Association of Equine Affiliated Academics (NAEAA) was held in conjunction with ESS May 30-31.

ESS is held every two years in different locations and promotes quality research on equine nutrition, reproductive physiology production, and management, teaching, and extension. The event is set up to establish effective communication among researchers, teachers, extension, and production personnel.

Following are titles of research presented at ESS by UK researchers (in bold below). The abstracts were published in the May/June 2011 issue of the Journal of Equine Veterinary Science.

Laurie Lawrence, PhD, professor in the Department of Animal and Food sciences in UK's College of Agriculture, co-authored several studies. They included:

  • Basal insulin and glucose concentrations in gestating and lactating mares, SM McCown, M Brummer, S Hayes, JE Earing, and LM Lawrence.
  • Effect of selenium depletion on oxidative stress in mature horses, M Brummer, S Hayes, JE Earing, SM McCown, and LM Lawrence.
  • Nutrient and dry matter intakes of broodmares fed high forage diets, SM McCown, M Brummer, S Hayes, JE Earing, and LM Lawrence.
  • Techniques, equipment and considerations applied in equine digestibility experiments M. Edwards, LM Lawrence, and C. O'Connor-Robison.
  • Growth rates in 3- and 4-month-old foals during the summer in Central Kentucky, L Strasinger and LM Lawrence.
  • The effect of endophyte-infected tall fescue on weanlings, BE Davis and LM Lawrence.
  • Factors affecting live foal rates of Thoroughbred stallions in Kentucky, BE Davis and LM Lawrence.

Lawrence collaborated with several other UK faculty members, including Mary Rossano, MS, PhD, assistant professor in the Department of Animal and Food Sciences, and Eugene Lyons, PhD, Department of Veterinary Science, in the study, "Effects of windrow composting on the viability of Parascaris equorum eggs within the interior of the windrow," JC Gould, MG Rossano, ET Lyons, and LM Lawrence. She collaborated with David Horohov, PhD, William Robert Mills chair and professor at the Gluck Center, and others to research "Selenium depletion reduces vaccination response in horses," M Brummer, S Hayes, SM McCown, AA Adams, DW Horohov, and LM Lawrence.

Horohov's Gluck Equine Research Center laboratory collaborated with researchers at Rutgers, The State University of New Jersey, University of Pennsylvania, and Michigan State University on the study titled, "The effect of exercise training on insulin sensitivity and fat and muscle tissue cytokine profiles of old and young Standardbred mares," NR Liburt (Rutgers, The State University of New Jersey), MN Fugaro (Centenary College), EK Wunderlich (Rutgers, The State University of New Jersey), JL Zambito (Rutgers, The State University of New Jersey), DW Horohov, A Betancourt, RC Boston (University of Pennsylvania), KH McKeever (Rutgers, The State University of New Jersey), and RJ Geor (Michigan State University).

Horohov's laboratory also collaborated with others at UK, including Kristine Urschel, PhD, an assistant professor in Animal and Food Sciences and lead for the project, "The effects of non-steroidal anti-inflammatory drug administration on systemic and muscle inflammation in mature and aged horses," AL Wagner, RB Ennis, A Betancourt, AA Adams, DW Horohov, and KL Urschel.

Other projects Urschel co-authored included:

  • Supplemental leucine's influence on plasma glucose, insulin, and amino acid responses in Quarter Horse yearlings by LC Etz (Pennsylvania State University), NM Lambert (Pennsylvania State University), JT Sylvester (Mars Horsecare US Inc.), KL Urschel, and WB Staniar (Pennsylvania State University).
  • Amino acid concentrations in late lactation mares' milk, SL Tanner, AL Wagner, RB Ennis, and KL Urschel.
  • Postprandial changes in plasma free amino acids in weanling horses, RN Digianantonio, AL Wagner, SL Tanner, RB Ennis, PA Harris (WALTHAM Centre For Pet Nutrition), JT Sylvester (Buckeye Nutrition), and KL Urschel.

There were also two studies conducted by faculty and graduate students at the Gluck Center, including one by the infectious disease and genetics/genomics group when Udeni Balasuriya, BVSc, MS, PhD, professor of virology at the Gluck Equine Research Center, and PhD candidate Yun Young Go collaborated with Ernie Bailey, PhD, professor in the Department of Veterinary Science.

Genome wide association study for susceptibility of horses for in vitro infection with equine arteritis virus, YY Go, U Balasuriya, and E. Bailey.

Mats Troedsson, DVM, PhD, Dipl. ACT, director of the Gluck Center and chair of the department of veterinary science, led a reproduction study. Ed Squires, PhD, Dipl. ACT (hon.), director of the Equine Initiative and executive director of the UK Gluck Equine Research Foundation, was also included in the proceedings:

  • Fertility of mares inseminated with frozen/thawed semen centrifuged through a single layer density gradient, KL Cerny, S Hughes, JR Campos, MHT Troedsson, and EL Squires.
  • In another Gluck Center study Teri Lear, PhD, associate professor in the genetics/genomics group at the Gluck Center, and Judy Lundquist, a research technician, collaborated with Terje Raudsepp, PhD, an assistant professor at Texas A&M and local practitioner and Gluck Foundation Board member Stuart Brown, DVM:
  • A chromosome translocation [64,XX,t(2;13)] in a Thoroughbred mare with repeated early embryonic loss, TL Lear, T Raudsepp (Texas A&M), J Lundquist, and S Brown (Hagyard Equine Medical Institute).

Other UK studies included:

  • Effect of ivermectin and fenbendazole on fecal egg count reduction among foals in Virginia by AC Carrington (Virginia Tech), JL Carrington (Virginia Tech), JC Gould, RM Brooks (Virginia Tech), CA Porr (Virginia Tech), and RK Splan (Virginia Tech).
  • Developing an assessment plan in an animal science department, S Burk, M Rossano, E Vanzant, W Silvia, and R Harmon.
