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.
Pulse RE, Baker JP, Potter GD.Three mature Thoroughbred geldings were used in duplicated trials conducted before and after cecal fistulation to determine the effects of the fistulation on nutrient digestion and indicator (Cr2O3 and polyethylene) retention time. There were significant increases (P<.01) in crude fiber and ether extract digestion following fistulation, while dry matter, gross energy, and crude protein digestibilities were not changed significantly. Retention times of Cr2O3 and polyethylene were increased significantly (P<-01 and P<.05, respectively) following fistulation. There were no significant differences...
McGuire TC, Poppie MJ.A severe combined immunodeficiency disorder was demonstrated in two Arabian foals which were full siblings. The defect in the B-lymphocyte system was shown by hypogammaglobulinemia, lymphopenia, and absence of germinal centers. The almost total absence of thymic tissue in one foal and the lack of thymic dependent lymphocytes in the spleens of both foals demonstrate a T-lymphocyte defect. In a retrospective study of total available Arabian foal cases, 4 of 15 had evidence of immunodeficiency.
Gygax AP, Donawick WJ, Gledhill BL.A stallion was examined because of a pronounced scrotal swelling of three weeks' duration. A sudden loss of fertility with the finding of increased numbers of abnormal sperm indicated degeneration of the seminiferous epithelium. Based on the results of the physical examination and analysis of fluid aspirated from a fluctuant portion of the swelling, a tentative diagnosis of haematocoele was made. Unilateral castration was performed.
Periodic examination of the stallion's semen for eight months after surgery indicated recovery of normal spermatogenesis in the remaining testis. The fertility ...
Schara M, Nemec M, Falnoga I, Kobal AB, Kveder M, Svetek J.The action of mercuric chloride and methyl mercuric chloride on the membrane lateral domain organization of bovine, equine, and canine erythrocytes was studied. Electron paramagnetic resonance (EPR) spectra of spin-labeled erythrocytes were analyzed with respect to their lateral domain structure. Continuous alteration of the membrane domain populations revealed that mercuric compounds affect the membrane via the evolution of toxic events in the cells.
Eddy AL, Galuppo LD, Stover SM, Taylor KT, Jensen DG.To compare mechanical properties and failure characteristics of 2 methods of fixation for repair of a transverse, midbody fracture of the proximal sesamoid bone (PSB): 4.5-mm AO cortical bone screw (AO) placed in lag fashion and 4/5-mm Acutrak (AT) self-compressing screw. Methods: An in vitro biomechanical evaluation of intact forelimb preparations and forelimb preparations with a simulated midbody PSB fracture stabilized by a bone screw. Methods: Sixteen paired and 8 unilateral cadaveric equine forelimbs. Methods: A midbody transverse osteotomy was created in the medial PSB of bilateral forel...
McClure SR, Hooper RN, Watkins JP.A 13-month-old Quarter Horse colt sustained a puncture wound to the frog region of the foot, which penetrated the navicular bursa and distal interphalangeal joint, 7 days prior to examination. A street-nail procedure was performed to debride the tract and provide drainage of the navicular bursa and distal interphalangeal joint. An indwelling lavage system was placed through the dorsal aspect of the joint and antimicrobials were infused intermittently to supply a high local concentration of drug and to frequently lavage the distal interphalangeal joint and navicular bursa.
Martin EM, Schirmer JM, Jones SL, Davis JL.Misoprostol is an E prostanoid (EP) 2, 3 and 4 receptor agonist that is anecdotally used to treat and prevent NSAID-induced GI injury in horses. Misoprostol elicits anti-inflammatory effects in vivo in men and rodents, and inhibits TNFα production in equine leucocytes in vitro. Objective: Define the pharmacokinetic parameters of oral misoprostol in horses, and determine the inhibitory effect of oral misoprostol administration on equine leucocyte TNFα production in an ex vivo inflammation model. Methods: Pharmacokinetic study, ex vivo experimental study. Methods: Six healthy adult horses ...
Tamayo-Arango LJ, Mejía-Durango MA.Gross anatomy is considered one of the most challenging subjects in teaching veterinary medicine. The use of body painting is reported in teaching surface human anatomy, but such reports are scarce in veterinary medicine. The aim of this study was to describe a practical session for teaching surface anatomy using body painting with second-semester students of veterinary medicine. Two practical sessions using live animals (equine and bovine) were offered with a focus on the locomotor and nervous systems and splanchnology. Students believed that the body painting sessions helped them to understa...
Thompson DL, Reville SI, Derrick DJ.Five mature Quarterhorse mares were bled every 30 min for 25 h on day 50 of pregnancy to determine the short-term mode of secretion of equine chorionic gonadotropin (eCG). Three other mares with persistent endometrial cups after abortion were administered gonadotropin releasing hormone (GnRH; 1.0 mug/kg of body weight) and were bled immediately prior to and at 15, 30, 45, 60, 90, 120, 180 and 240 min after GnRH. Concentrations of eCG in plasma of pregnant mares were constant over the 24-h period; the variation of each mare's individual values was no greater (P>.05) than the predicted random...
Polten B.Since the last report there have been major revisions of laws and ordinances. Deliberations on rules of Community law were also continued. On national level, the Act on the Shoeing of Horses amending the Animal Welfare Act and amendments of animal welfare provisions as well as the Deregulation Act were prepared, some of which have meanwhile entered into force. At legislative level, the work on the ratification laws for the Council of Europe conventions (Strasbourg) was concluded in order to enable Germany to adopt the revisions. They include (1) the European Convention for the protection of an...
Reinemeyer CR, Herd RP.Haustral portions of intestine of 6 horses were isolated by excising the taeniae coli from the cecum and the ventral colon. Uniform 5-cm X 5-cm sections were cut from the haustra and were illuminated from the serosal side with a strong light source (mural transillumination). Cyathostome larvae encysted in the mucosa and submucosa were observed at 15 X magnification and counted. Two separate counts of the larvae in 80 replicates of tissue by the mural transillumination technique (MTT) revealed no significant (P less than 0.05) difference between sample means. Larvae in tissue sections were coun...
Kay AD, Lavoie JP.A technique was developed for recording urethral pressure profiles (UPP) in mares. Profiles were obtained from 12 clinically normal mares and from 3 mares with urinary incontinence. Variables measured on the profile included intravesicular pressure and maximal urethral closure pressure. The mean maximal urethral closure pressure of the incontinent mares was significantly less (P less than or equal to 0.001) than that of the normal mares. The technique is simple and reliable for objectively evaluating urethral pressures in mares.
