Bovine Colostrum Supplementation Optimises Earnings, Performance And Recovery In Racing Thoroughbreds, C. K. Fenger, Thomas Tobin, P. J. Casey, Edward A. Roualdes, J. L. Langemeier, D. M. Haines

Maxwell H. Gluck Equine Research Center Faculty Publications

Bovine colostrum (BC) is the first milk produced by cows after calving and contains numerous beneficial substances for the immunity and development of the newborn calf. Because of the growth and immune factors in BC, it has become an attractive supplement for use by athletes to support immunity and health during athletic performance. In order to evaluate the effects of oral BC supplementation on equine athletes, this study evaluated the earnings, performance, recovery and incidence of upper respiratory infections (URTI) in racing horses. The study design was a randomized cross-over racing performance study. 21 horses in race training were randomly …

Differentiation Of Equine Mesenchymal Stromal Cells Into Cells Of Neural Lineage And Their Application Into A Novel Model For Acute Peripheral Nerve Injury In The Horse, Claudia Cruz

Masters Theses

Studies have shown that mesenchymal stromal cells (MSCs) are able to differentiate into extra-mesodermal lineages, including neurons. Positive outcomes were obtained after transplantation of neurally-induced MSCs in rats, rabbits and guinea pigs after nerve injury, but the effect of these cells is unknown in horses. Our objective was to test the ability of equine mesenchymal stromal cells to differentiate into cells of neuronal lineage, and to assess differences, if any, in morphology and protein expression. Additionally, we wanted to investigate if horse age and cell passage number contributed to the ability to achieve neural differentiation.

Intraocular Pressure Changes In Equine Athletes During Endurance Competitions, Rachel A. Allbaugh, Susan M. Keil, Zhining Ou, Nora M. Bello

Rachel A. Allbaugh

Objective To assess intraocular pressure (IOP) in conditioned equine athletes and document changes with exercise. A secondary objective was to assess associations between IOP and heart rate, as well as with other subjective physical parameters.

Sample Population Horses were evaluated during 50 mile endurance ride competitions. Data were collected on 69 horses during 5 different competitions at 3 different locations with 59 horses ridden once, 9 horses ridden in two competitions, and 1 horse ridden in three competitions for a total of 80 horse-ride combinations.

Procedures Intraocular pressure was measured using a TonoVet® tonometer in both eyes of each horse …

Polymorphism In Introns 5 And 6 Of The Acta1 Gene In Various Polish Horse Breeds, Daniel Polasik, Ryszard Pikula

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to find polymorphisms in the actin alpha 1 gene (ACTA1) in horses belonging to different breeds and utility types and to compare them. The genomic region of the actin alpha 1 gene was positively selected in purebred horses. By sequencing part of the ACTA1 gene, 2 polymorphic sites located in intron 5 (G > T) and intron 6 (G > C) were found. The polymerase chain reaction-restriction fragment length polymorphism and the amplification created restriction site-polymerase chain reaction methods were applied to screen these polymorphisms. An analysis of the genotype and allele frequencies showed differences depending …

Serological Survey Of Equid Herpesvirus 3 Infection In Turkish Horses, Veysel Soydal Ataseven, Firat Doğan, Seval Bi̇lge Dağalp, Mehmet Tolga Tan, Köksal Altinbay, Cafer Tayyar Ateş

Turkish Journal of Veterinary & Animal Sciences

Sera from 1133 Turkish horses were obtained and tested for equid herpesvirus 3 (EHV-3) antibodies using a sero-neutralisation test. The sample consisted of 420 privately owned working horses from 2 regions of Turkey, 428 brood horses from private stud farms and breeding stations, and 285 racehorses from private stud farms. Neutralising antibodies against EHV-3 were found in 287 (25.3%) of the 1133 analysed sera. The highest seroprevalence for EHV-3 was detected in the brood horses (51.2%), followed by the racehorses (10.2%), and the working horses (9.3%). The seroprevalence rates tended to be higher in female horses than in male horses …

The Roles Of Orthopaedic Pathology And Genetic Determinants In Equine Cervical Stenotic Myelopathy, Jennifer Gail Janes

Theses and Dissertations--Veterinary Science

Cervical stenotic myelopathy (CSM) is an important musculoskeletal and neurologic disease of the horse. Clinical disease occurs due to malformations of the vertebrae in the neck causing stenosis of the cervical vertebral canal and subsequent spinal cord compression. The disease is multifactorial in nature, therefore a clearer understanding of the etiology and pathogenesis of CSM will allow for improved management and therapeutic practices. This thesis examines issues of equine CSM diagnosis, skeletal tissue pathology, and inherited genetic determinants utilizing advances in biomedical imaging technologies and equine genomics. Magnetic resonance imaging (MRI) data provided a more complete assessment of the cervical …
