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.
RANDALL CC, WALKER BM.Randall, Charles C. (University of Mississippi School of Medicine, Jackson) and Barbara M. Walker. Degradation of deoxyribonucleic acid and alteration of nucleic acid metabolism in suspension cultures of L-M cells infected with equine abortion virus. J. Bacteriol. 86:138-146. 1963.-Metabolic alterations in log-phase suspension cultures infected with equine abortion virus (EAV) were determined in L-M cells simultaneously labeled or prelabeled with H(3)- or C(14)-thymidine. Although infection produced an early stimulation of the uptake of labeled thymidine (TdR) into the acid-soluble fraction of...
WIDE M, WIDE L.THE use of a hæmagglutination inhibition reaction for the diagnosis of pregnancy in women was reported by Wide and Gemzell1 and Wide2. In this reaction human chorionic gonadotrophin (HCG) inhibited the agglutination of stable HCG-coated blood cells. The same immunological technique was applied for the assay of pregnant mare serum gonadotrophin (PMS) and was used as a pregnancy diagnosis test in mares. Sera from pregnant mares containing elevated levels of gonadotrophin inhibited an agglutination reaction of PMS-coated formalinized erythrocytes in the presence of PMS anti-serum, while sera fro...
ROBERTS SR.The research article explores the origin or causation (etiology) of an ancient horse disease known as equine periodic ophthalmia, where clinical and pathological investigations have yet to yield conclusive results. […]
BOYD WL, BOYD JW.Boyd, William L. (Ohio State University, Columbus) and Josephine W. Boyd. Viability of coliform bacteria in antarctic soil. J. Bacteriol. 85:1121-1123. 1963.-The distribution of coliform bacteria in soils of Ross Island and the nearby mainland was studied. None was found in almost all of the samples collected, including some from the Adelie penguin rookeries at Cape Royds and Cape Crozier and in soil at the McMurdo Base which had been recently contaminated by human sewage. Samples of pony manure left from previous expeditions were also negative, with one exception where Escherichia coli were p...
Shand N, Irvine CH, Turner JE, Alexander SL.Jugular blood samples were collected at 4 h intervals from six mares during an oestrous cycle to study the hormonal events that occur around the time of luteolysis. Blood samples from day 10 (day 0 = ovulation) until day 3 of oestrus were assayed for prostaglandin metabolite 13,14-dihydro-15-keto PGF2alpha (PGFM), oxytocin, prolactin, progesterone and oestrogen conjugates. PGF2alpha (0.5 or 1.5 mg) was administered to six mid-dioestrous mares and the oxytocin and prolactin responses were measured. One to five large (peak > or =2 x nadir) pulses of PGFM, oxytocin and prolactin were detected ...
Moslemi S, Silberzahn P, Gaillard JL.19-Norandrostenedione was synthesized in vitro from dehydroepiandrosterone by explants of equine full-term placenta. The synthesis of 19-norandrostenedione was inhibited by two specific aromatase inhibitors, 4-hydroxyandrostenedione and fadrozole.
Cermák O.An attempt was made to express the relationship of spermiological characteristics with the fertility on the basis of seasonal variability of the fertility of stallions and of the ejaculate quality. A positive correlation between the activity of spermatozoa and the fertility ensues from the values of correlation coefficients. There is a negative correlation between the fertility and the concentration of citric acid. In the other characteristics, i.e. in the production of spermatozoa, volume of gel substance, pH, ergothioneine concentration, polarographic and hemolytic activity, the correlation ...
Pal AK, Gupta T, Chatterjee A.A single consistent luteolytic dose of 10 IU PMSG given on day 5 of pregnancy caused complete resorption of foetuses and placentae associated with a polyfollicular ovarian state in rats. Concomitant treatment with progesterone or prolactin given concurrently with PMSG was found to overcome the antifertility efficacy of PMSG and maintained the endocrine balance favouring pregnancy maintenance. It was postulated that the PMSG-induced ovarian polyfolliculogenesis might be responsible for luteolysis of the corpus luteum gravidarum.
Berndtson WE, Jones LS.Testes were obtained from 47 1-20-year-old stallions during the natural breeding season. Total testicular testosterone and testosterone/g testis increased with age (P less than 0.005), and total testicular testosterone was associated with larger testis size (P less than 0.05). Neither testosterone per gram nor per paired testes were related to total Sertoli cell number (P greater than 0.05), but greater testosterone per paired testes was associated with fewer Sertoli cells per unit of seminiferous tubule length (P less than 0.005) or basement membrane area (P less than 0.02) and with a higher ...
Breuil MF, Joseph M, Petry S.The gold standard method to isolate and identify Taylorella equigenitalis, the contagious agent of equine metritis, is the culture method according to the World Organisation for Animal Health Terrestrial Manual. No selective T. equigenitalis chocolate agar medium has been developed since the 1980s and the existing media show limited performances due to the fastidious nature of T. equigenitalis and the presence of interfering bacteria in the genital tract of equines. Here, the growth rates of 6 T. equigenitalis strains and 7 non-T. equigenitalis strains were compared on Timoney's selective medi...
Simon O, Laverty S, Bouré L, Marcoux M, O Szöke M.To describe the outcome after arthroscopic electrosurgical excision of axial osteochondral (OC) fragments of the proximal plantar aspect of the 1st phalanx (P1) in horses. Methods: Retrospective study. Methods: Twenty-three Standardbred racehorses. Methods: Medical records of Standardbred racehorses that had arthroscopic dissection of axial OC fragments of the proximal plantar aspect of P1 with electrocautery probes were reviewed. Horses were positioned in dorsal recumbency; a 1.5% glycine solution was used to maintain joint distension. The arthroscope portal was in the proximal plantar joint ...
Dutton DM, Honnas CM, Watkins JP.To determine the outcome of horses with suprascapular nerve injury treated with stall rest alone. Methods: Retrospective case series. Methods: 8 horses. Methods: Information on signalment, history, limbs affected, severity of lameness, degree of muscle atrophy, gait abnormalities, and results of radiography and electromyography was obtained from medical records. All horses were treated with stall rest. Follow-up information on severity of lameness, gait abnormalities, degree of muscle atrophy, time between injury and resolution of gait abnormalities, and outcome was obtained during reexaminati...
Suminda GGD, Ghosh M, Son YO.For more than a decade, next-generation sequencing (NGS) has been emerging as the mainstay of agrigenomics research. High-throughput technologies have made it feasible to facilitate research at the scale and cost required for using this data in livestock research. Scale frameworks of sequencing for agricultural and livestock improvement, management, and conservation are partly attributable to innovative informatics methodologies and advancements in sequencing practices. Genome-wide sequence-based investigations are often conducted worldwide, and several databases have been created to discover ...

Cremonesi F, Anderson K, Lange-Consiglio A.TWO METHODS HAVE BEEN DESCRIBED TO RECOVER OOCYTES FROM EQUINE FOLLICLES IN EXCISED OVARIES: aspiration and scraping. Aim of this work was to develop an effective method for collecting equine oocytes using Tuohy needle and comparing this technique to aspiration and scraping, with or without tunica albuginea removal. This hollow hypodermic needle, usually employed for inserting epidural catheters, is designed with a slightly curved tip, shaped similar to a small curette. In unpeeled ovaries, the recovery rates of Tuohy needle group was higher (P < .05) than in the 16 g needle aspiration and ...
