Equine health encompasses the study and management of diseases, disorders, and overall well-being of horses. It involves understanding various physiological systems, preventive care, and treatment strategies to maintain optimal health in equine populations. Common areas of focus include nutrition, infectious diseases, orthopedic conditions, and reproductive health. Research in equine health aims to advance knowledge on diagnostic methods, therapeutic interventions, and management practices that improve horse welfare and performance. This page collects peer-reviewed research studies and scholarly articles that explore the diverse aspects of equine health, offering insights into current findings and advancements in the field.
HABEEB AF, SMITH DB.Horse globill and its conlponent polypeptide chains obtained by fractional
precipitation and column chroinatography have been ailalyzed for their con- stituent amino acids. The principal difference between the two chains is that
the valyl-leucyl chain is rich in serine and threonine and poor in glutamic acid
and tryptophan compared to the \-alyl-glutaininyl chain.
HETRICK FM, YANCEY FS, HANSEN PA, BYRNE RJ. Four horses inoculated with EEE virus remained asymptomatic following injection but did develop measurable HI and neutralizing antibodies as a result of infection. HI antibodies were detectable earlier than neutralizing antibodies but the levels tended to drop more rapidly. 2. Of 14 horses and ponies having significant levels of neutralizing antibody, 5 to 9 had measurable HI antibody depending on number of units of antigen employed in the test. 3. Sera from 3 clinical cases of EEE were positive on the HI test while only one of these animals had a significant neutralizing antibody level.
BRAYE ET, HINSMAN EJ, RILEY WF.No horse receiving combined streptokinase, streptodornase, and human plasminogen alone in either 125,000-unit or 375,000-unit doses manifested any clinical reaction. Untoward reactions occurred in 2 horses receiving both the combined streptokinase, streptodornase, and human plasminogen (125,000 units), and chlortetracycline. The reaction was transitory and subsided without treatment.
Hornof WJ, Stover SM, Koblik PD, Arthur RM.The research article discusses a study on the use of oblique dorsal views in detecting stress fractures in horses who participate in races. The aim of the researchers was to […]
Williams S, Scott P.Meal contaminated by Datura stramonium seeds at the rate of 0.5% by weight was fed to two horses. Both horses showed clinical signs of depression, anorexia, weight loss, rapid heart and respiration rates, mydriasis, polyuria, polydipsia and diarrhoea. Both recovered with treatment. Maize screenings contaminated by the seeds had been used in the manufacture of the meal.
Tåmová B, Stumpa A, Zakopal J, Vĕzníková D, Mensík J.Equine influenza occurred in Czechoslovakia 14 years after the last epizootic in horses that had returned from abroad. Six strains A (Heq1Neq1) antigenically related to, but not identical with, strain A/eq/Praha/56 were isolated from 10 washings. Seroconversion was demonstrated with paired sera, but the antibody increase was more marked against the newly isolated strain.
Bondesson U, Johansson IM.This study demonstrates the development of a method using gas chromatography-mass spectrometry for determining nefopam, a non-narcotic pain reliever that is sometimes abused in horse doping, in equine plasma. Background […]
Whan G, Runciman RJ, Hurtig M.Whole bone in vitro biomechanical compressive testing can be complicated by three factors: sample asymmetry, heterogeneous material properties, and unknown effective centroid location. Methods: The technique presented here facilitates the calculation of effective centroid position, modulus of elasticity and equivalent uniform strain magnitude for a cross section of bone from a simple whole bone compressive test. Simplification of section response to load is achieved through a combination of linear beam and simple planer geometry theory. The technique requires three longitudinal strain gauges b...
Bishop J, Heffron B, Taddei L, Benoit M, Hurt L, Costello S, Gross M, Negrusz A.Clenbuterol (CLE) is used in horses as a bronchodilator and for its anabolic steroid-like effects. CLE is a Class 3 drug according to current Association of Racing Commissioners International (ARCI) Uniform Classification Guidelines. The Racing Medication and Testing Consortium recommended a urine CLE threshold of 140 pg/mL after careful scientific review of the results of studies describing the disposition of CLE in the horse and this threshold was adopted by the ARCI. Enzyme-linked immunosorbent assay was previously used to screen samples for CLE in Illinois, but could not detect such low co...
Chavatte-Palmer P, Duchamp G, Palmer E, Ousey JC, Rossdale PD, Lombès M.Progesterone, oestrogen and glucocorticoid receptor concentrations in the uterus and mammary glands of pregnant mares during mid- to late gestation (from day 150 of gestation to term) were measured by binding assays to investigate the hormonal mechanisms involved in pregnancy maintenance and lactation. Uterine progesterone receptor concentrations did not increase significantly with increasing gestational age (from 67.8 +/- 13.7 to 126.1 +/- 48.7fmol mg(-1) protein), whereas oestrogen receptor concentrations were significantly higher in pregnant mares (271.7 +/- 28.9 fmol mg(-1) protein) than i...
Heinonen E, Hedenstierna G, Meriläinen P, Högman M, Nyman G.To study the effect of the pulsed delivery of nitric oxide (NO) on pulmonary gas exchange in the anaesthetized horses. Design Prospective, controlled randomized. Methods: Five healthy Standardbred trotters, three geldings and two mares. Methods: The horses were anaesthetized with thiopentone and isoflurane and positioned in dorsal recumbency. Nitric oxide was added as a pulse to the inspired gas during the first half of each inspiration. In three horses the effect of NO on the ventilation-perfusion distribution was also investigated using the multiple inert gas elimination technique. Data w...
Mellish MA, Adreani CM.A 5-year-old, Quarter horse mare was treated for severe cellulitis secondary to a gunshot wound near the right humerus. The bullet was not retrieved due to the risk of damaging the radial nerve or elbow joint. Despite the presence of the bullet, the mare resumed athletic soundness once the infection had resolved. Traitement d’une blessure par balle chez une jument. Une jument Quarter horse âgée de 5 ans a été traitée pour une cellulite sévère à la suite d’une blessure par balle près de l’humérus droit. Le projectile n’a pas été retiré par crainte de léser le nerf radial o...
Aubert MF.The author describes a method for evaluating the minimal number of diagnosis failures for each animal species (this diagnosis uses the Fluorescent Rabies Antibodies Test and mouse inoculation simultaneously). The percentage of well diagnosed rabid animals on total rabid ones is called sensibility of the diagnosis: it varies according to the species of animal examined: from 99.98% for the fox, to 98.61% for the horse. The percentage of errored negative diagnosis on total negative diagnosis is called infidelity of negative responses: it varies for each species according to the sensibility of the...
Glatthaar R.In April 1996 an attack of black flies (Diptera, Simuliidae) to horses was observed in the region of Basle, Switzerland. Females of Simulium erythrocephalum and Simulium ornatum were involved in this attack, part of them had taken a blood meal. For S. ornatum this is the first record in Switzerland that this species takes blood meals on horses.
Mattacola CG, Quintana C, Crots J, Tumlin KI, Bonin S. During thoroughbred races, jockeys are placed in potentially injurious situations, often with inadequate safety equipment. Jockeys frequently sustain head injuries; therefore, it is important that they wear appropriately certified helmets. The goals of this study are (1) to perform impact attenuation testing according to ASTM F1163-15 on a sample of equestrian helmets commonly used by jockeys in the United States and (2) to quantify headform acceleration and residual crush after repeat impacts at the same location. Seven helmet models underwent impact attenuation testing according to ASTM...

Borges LM, Ferreira LA, da Silva LS, de Oliveira RA, Mussi SV, Faria KA, Melo LS, Abud LJ, Costa GL, Soares SF.This study was carried out with the objective of evaluating the efficacy of a 2,6-dichlorophenol (2,6-DCP) lure to control Dermacentor nitens (Acari: Ixodidae). Slow-release formulations of the pheromone formulated with and without cypermethrin were prepared. Olfactometer bioassays were used to define the best dose of the pheromone and to evaluate the effect of cypermethrin with 2,6-DCP attractiveness. Sexually active males were released 15 cm from 2 cmx1 cm pieces of polypropylene treated with different odors: 2,6-DCP in a liposphere system (1.5, 30 and 300 microg--without cypermethrin and 30...
Ogilvie GK, Engelking LR, Anwer MS.Ten horses, a pony, and 13 cats were used to evaluate base-line blood ammonia, bilirubin, and urea nitrogen concentrations and to determine The effects of prolonged cold storage (-20 degrees C) before assay. Base-line plasma ammonia concentrations in cats (0.992 +/- 0.083 [SE] micrograms/ml) did not change significantly after 48 hours of storage (0.871 +/- 0.073 micrograms/ml); however, they were increased 4.2- and 13-fold after 168 and 216 hours of storage, respectively. In contrast to base-line plasma-ammonia values in cats, those of horses were significantly (0.265 +/- 0.044 micrograms/ml) ...
