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.
Basrur PK, Kanagawa H, Podliachouk L.An intersex horse exhibiting cell types of different sex chromosome constitution was subjected to further studies in order to determine whether the house was a mosaic or a chimera. Cultures of gonadal tissue and peripheral blood revealed mainly 64/XX and 64/XY cells, the former predominating in both tissues. The frequency of drumstick-bearing poly-morphonuclear neutrophils in the intersex horse was similar to that noted in normal mares. Blood type analysis using 17 naturally occurring agglutinins and hemolysins revealed partial agglutinations with three antibodies for the factors of the A syst...
Norby MA, Link RP.Thirty horses were anaesthetized with halothane and thiopental sodium. To determine the hepatotoxic effect of halothane, bromsulphalein (BSP) tests for liver function were made immediately before and 24 hours after anaesthesia and surgery. The periods of anaesthesia varied from 35 minutes to 3 1/2 hours. Results of these tests indicated no significant impairment of liver function 24 hours after anaesthesia, the time at which liver damage due to chloroform, which has a molecular structure similar to that of halothane, has reached its peak

Schryver HF, Craig PH, Hintz HF, Hogue DE, Lowe JE.The site of calcium absorption in the horse was studied by the following techniques: 1) comparison of the degree of absorption of 47Ca deposited directly in a fistulated cecum versus that absorbed from an intragastric dose; 2) estimating apparent absorption in various regions of the intestinal tract, using Cr2O3 as an unabsorbable marker; 3) comparison of the degree of absorption of 47Ca from in vivo intestinal sacs of duodenum, ileum, cecum and colon. The upper part of the small intestine appeared to have the greatest calcium absorptive potential and to be the major effective site of net calc...
Baird JD, Hutchins DR, Lepherd EE.A 12-month-old thoroughbred horse, after being treated with 30 g. of micronized phenothiazine, developed an acute haemolytic anaemia characterized by Heinz-body formation. Elevation of serum glutamic oxaloacetic transaminase, isocitric dehydrogenase, lactate dehydrogenase and blood urea nitrogen also occurred. The colt's clinical condition improved after receiving blood transfusions, fluids, antibiotics and corticosteroids. After 10 weeks, the haematological and biochemical picture returned to normal.

Fransson LA, Havsmark B.The structure of dermatan sulfate-chondroitin sulfate
copolymers, isolated from horse aorta, has been examined.
It was found that a large proportion of the galactosaminoglycans of this tissue was obtained as a discrete polysaccharide fraction with an L-iduronic acid to D-glucuronic
acid ratio of approximately 1: 2. This finding together with
infrared data indicated that the polymer contained approximately equimolar proportions of the three repeating disaccharide units glucuronosyl-N-acetylgalactosamine 4-sulfate
(A), iduronosyl-N-acetylgalactosamine 4-sulfate (B), and
glucuronosyl-N-acet...
Hernandez-Vidal G, Jeffcott LB, Davies ME.The distribution of cathepsin D in normal equine growth cartilage has been examined immunocytochemically using an antiserum raised against human cathepsin D. The cross-reactivity and specificity of the antiserum for equine cathepsin D was confirmed, and its lysosomal localisation was demonstrated in horse skin fibroblasts by confocal scanning microscopy. Cultured horse chondrocytes were heterogenous in their expression of cathepsin D. Heterogeneity of distribution of the enzyme was also seen in chondrocytes in cartilage from different anatomical sites. A high level of cathepsin D was observed ...
Bergman HJ, de Kruif A, van Dessel S.A review is given of treatment for 'problem' mares that do not become pregnant. To determine the best therapy, it is necessary to understand the defence mechanisms of the uterus and the pathogenesis of not getting in foal. A thorough clinical examination is absolutely necessary to come to a correct diagnosis. This examination will be explained in a practical way. In the second article the different therapies for treating problem mares are discussed. The therapeutic possibilities vary widely. They can be classified in: anatomical corrections, anti-infectious therapy, and treatment to enhance th...
Grogan EH, McDonnell SM.To evaluate behavioral compliance of horses and ponies with simulated intranasal vaccination and assess development of generalized aversion to veterinary manipulations. Methods: Clinical trial. Methods: 28 light horse mares, 3 pony geldings, 2 light horse stallions, and 3 pony stallions that had a history of compliance with veterinary procedures. Methods: Behavioral compliance with 2 intranasal vaccine applicators was assessed. Compliance with standard physical examination procedures was assessed before and after a single experience with either of the applicators or a control manipulation to e...
Furr M, Chickering WR, Robertson J.To determine normal CSF electrophoresis patterns in horses, and to determine whether the electrophoretic scans from horses with cervical compression differ from those of neurologically normal horses. Methods: 32 horses assigned to 1 of 2 groups: neurologically normal (n = 18) or cervical compression (n = 14). Methods: CSF was collected from 18 neurologically normal horses referred to the Marion duPont Scott Equine Medical Center, and protein electrophoresis was performed to describe the normal equine CSF electrophoretogram. Results of CSF electrophoresis from 14 horses with cervical compressio...
Swerczek TW.Unexplained clinical signs of weight loss and emaciation were reported in a herd of Thoroughbred horses grazing spring pastures on a central Kentucky farm, even though supplemental grain and hay were provided. Results: A buttercup plant, Ranunculus bulbosus L, was abundantly present in all pastures and paddocks on the farm. All horses, especially lactating mares and their foals, had mild to severe weight loss as assessed by body condition. Seven mares on the farm had been confirmed pregnant between 30 and 45 days of gestation, but were later found to have aborted. Two 2-year-old fillies develo...
Goodrich LR, Furr MO, Robertson JL, Warnick LD.A double-blind study was performed, in horses, to determine the potential toxic effects of the nonsteroidal anti-inflammatory drug, eltenac(4-[(2,6-dichlorophenyl) amino]-3-thiopheneacetic acid). Four treatment groups of six horses were formed. The drug was injected intravenously, once daily, at a dose level of 0.5 mg/kg, 1.5 mg/kg or 2.5 mg/kg for 15 days. A control group was injected with sterile saline solution. Horses were monitored for changes in appetite, physical examinations, biochemical evaluations and gastroscopic examinations. Complete post-mortem examinations were also performed. A...
Sharp DC, Grubaugh W, Berglund LA, McDowell KJ, Kilmer DM, Peck LS, Seamans KW, Chen CL.The pituitary stalk was transected in 10 Pony mares by a surgical approach that involved dorsal reflection of the brain and micro-dissection from the ventro-lateral aspect of the pituitary. Diabetes insipidus was the most immediate and marked result, requiring extensive electrolyte and antidiuretic therapy for approximately 48 h after operation. Fluid stasis then developed and no further supportive measures were necessary. Endocrine challenge tests with GnRH and TRH before and after stalk transection indicated a loss of responsiveness (GnRH) or suppressed responsiveness (TRH) after the operati...
