Topic:Equine Health
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.
Tumours of the prostate and penis. Tumours of the male genital tract, excluding the testes, are relatively rare in the six major domestic animals. The most important tumours are prostate carcinoma and transmissible venereal tumour of the penis in dogs, fibropapilloma of the penis in bulls, squamous papilloma and squamous cell carcinoma in horses, and squamous papilloma in pigs. Four histological types of canine prostate carcinoma exist: alveolar papillary, acinar, organoid, and poorly differentiated. The biological behaviour of prostate carcinomas is similar to that in man, with frequent metastasis to the regional pelvic nodes,...
Intra-articular treatment of arthritis in race-horses with sodium hyaluronate. Forty-five race-horses with arthritis of non-in-fectious type in 54 joints were treated with sodium hyaluronate intra-articularly. All joints had previously been treated without lasting success by conventional methods, such as firing, blistering or intraarticular injection of cortisone. In most cases only 1 injection of 2 ml (20 mg) sodium hyaluronate was needed. To avoid subjective evaluation, the effects of the treatment were based on the joint’s capacity of withstanding extreme stress, which means that the horse should be able to train and race again. The treatment was concentrated on the...
Behaviour of the heart rate of horses with auricular fibrillation during exercise and after treatment. Cardioversion through varying quinidine sulphate treatments was achieved in 3 riding horses with auricular fibrillation. The horses were subjected to continual telemetric ECG registration before and after reversion in a uniform exercise-tolerance-test. A comparison of the heart rate curves showed a strong decline of the heart beat frequency during the exercise phase after synchronisation. The decrease in heart rate during exercise was greater than 30% in all 3 patients. Anti-arrhythmic treatment is, therefore, recommended for horses with auricular fibrillation and without concurrent heart dise...
N-acetylserine in horse muscle acylphosphatase. A ninhydrin-negative peptide fraction obtained from tryptic digest of carboxymethyl acylphosphatase was isolated by chromatography on a column of PA 28 Beckman resin and analysed for the amino acid composition. Degradation with carboxypeptidase B and A indicated that the sequence of this peptide was: X-Thr-Ala-Arg. The amino-terminal residue was identified as N-acetylserine by high voltage electrophoresis. It is therefore suggested that the sequence of the NH2-terminal portion of CM-acylphosphatase is N-acetyl-Ser-Thr-Ala-Arg. Digestion with carboxypeptidase A and B indicated also that the COO...
Lipids of human and equine smegma. The lipids of human and equine smegma pools were saponified and the total fatty acids submitted to temperature programmed gas chromatography (GC) analysis. In contrast to the human products, the horse smegma fatty acids contained very low odd saturated as well as olefinic branched chain acid contents. The cyclopropane fatty acid, 9,10-methyleneoctadecanoic acid, occurred in smegma sampled from men over 35 years of age but could not be detected in the pool from persons of 17-20 years of age nor in any of the equine mixtures. The alcoholic fraction from horse smegma contained about 85% sterol, t...
Suppression of synthesis of an IgG subclass in a persistent viral infection. Comparison of immunoglobulin levels of nine horses before and after infection with equine infectious anaemia (EIA) virus demonstrated a significant depression of serum IgG(T) at 2 months (P less than 0-001) and at 1 year (P less than 0-01) after infection. In contrast, the levels of IgGa were significantly increased at both times after infection. Another sixteen horses with EIA for 1-4 months were examined and there was also significant depression (P less than 0-001) of IgG(T) when compared to pre-infection levels. No significant changes in IgG(T), IgGa and IgM were noted in fourteen normal ho...
[Comparative morphological studies on the vascular systems of testes in cattle, swine, horse and dog under functional conditions]. The metacrylate and latex corrosion techniques were used to establish that the vascular system of testes is based on one coherent principle in common domestic mammals. The cone-shaped Plexus pampiniformis consists of numerous venous rami, between 0.25 mm and 1.0 mm in thickness and forming a dense vascular network, which practically encase the spiral-shaped A. spermatica interna (cooling coil principle). The testicular veins and arteries in the Tunica albuginea constitute a somewhat voluminous layer of vessels for dissipation of heat, with rami branching off radially into the testicular parenc...
[Esential comparative, morphological and topographical differences and characteristics of the cecum in man and domestic animals]. The caecum in man as a part of the large colon (intestinum crassum) differs morphologically and topographically from the caecum of domestic mammals. The caecum in domestic mammals differs not only from the human caecum but also comparatively morphologically and topographically among the domestic mammals. The appendix vermiformis does not exist in domestic mammals, which represents the main difference between the human caecum and that of domestic mammals. There are certainly some differences in the physiological function of the caecum in man and the caecum in domestic mammals, which are carnivo...
Equine serum lipids: serum lipids and glucose in Morgan and Thoroughbred horses and Shetland ponies. Concentrations of serum phospholipids, triglycerides, total cholesterol, nonesterified fatty acids, and glucose were determined for 9 months (September, 1972, to May, 1973) in 19 fasting horses and ponies (8 Morgan horses, 7 Thoroughbred horses, and 4 Shetland Ponies). Morgan horses had higher concentrations of total lipid than did Thoroughbreds, although the relative proportions of each type of lipid were similar in the 2 breeds. Shetland Ponies had higher nonesterified fatty acid and lower glucose concentrations than did either breed of horse. In both breeds of horses, concentrations of seru...
Oxibendazole: critical anthelmintic trials in equids. The efficacy of oxibendazole against gastrointestinal parasites of horses was evaluated by the critical test method. Naturally infected ponies of various ages were given single oral doses of 5, 10, or 15 mg-kg of bodyweight. The drug was highly effective against adult large strongylids (Strongylus vulgaris, S edentatus, S equins), adult small strongylids (especially species of the genera Cylicostephanus, Cylicocyclus, Cyaathostomum, and Triodontophorus), and adult and larval stages of the large pinworm, Oxyuris equi. There was no apparent dose-related differences in efficacy. Oxibendazole was ...
Luteolysis with prostaglandin F2alpha or an antiserum against an equine pituitary fraction in hysterectomized mares. Luteolysis, determined by corpus luteum weight and progesterone concentration in jugular blood, occurred in uterine-intact and in hysterectomized mares after injection of prostaglandin F2alpha or of an antiserum against an equine pituitary fraction. Results indicated that luteolytic effects of exogenous prostaglandin F2alpha and inhibition of the endogenous luteotrophic activity of the hypophysis (pituitary gland) by antiserum did not involve the uterus.
Cardiac monitoring during exercise tests in the horse. 1. Magnetic tape recording in preference to radio-telemetry. Different techniques for monitoring cardiac responses to exercise in the horse have been described and evaluated. For experimental work of this type in a normal training and racing environment, the electrode system described when used with a portable magnetic tape recording system provided the best means of obtaining useful and reproducible data.
Calf blood extract in treatment of equine foot lesions. A deproteinized calf blood extract (Solcoseryl: Solco Basle, Ltd, Switzerland) enhanced healing of induced and naturally-occurring lesions in the feet of 30 horses and donkeys.
Equine toxoplasmosis: a survey for antibodies to Toxoplasma gondii in horses. A nationwide sample of horses was tested to determine the prevalence of toxoplasma antibodies in equine animals. Of 1,294 serum samples from horses tested by the microtitration indirect hemagglutin test, 20% were positive. Among the popular breeds of horses, the following antibody prevalences were found: Arabian, 19%; Paint, 22%; Quarter Horses, 13%; Thoroughbred, 24%; and Standardbred, 17%. The antibody prevalence increased from 2% in horses 1 year of age to 18% in 2-year-olds, and rose to 38% in horses 12 years of age. Significant differences were not evident by broad geographic locations ac...
Immunity to Streptococcus equi. Using the long chain test, and in some cases the bactericidal test, to measure antibody, the development of the immune response in horses to Str. equi has been followed. Long chain indices in excess of 5.0, accompanied by strong bactericidal capacity, were recorded in serums after the full 3-dose immunisation course with a commercial vaccine. The full course elicited the most satisfactory antibody titres declined within the 12 month post-vaccination period, thus providing support for the recommendation that yearly booster doses should be administered. The immune response in horses during 2 str...
Equine serum lipids: serum lipoprotein profiles of Morgan and Thoroughbred horses. The serum of lipoproteins of 10 Morgan and 8 Thoroughbred horses were examined by 2 methods of polyacrylamide gel electrophoresis. A significant breed difference in the beta-lipoprotein to alpha-lipoprotein ratio was seen in gradient slab electrophoresis. A breed difference in the number of peaks, but no difference in beta-lipoprotein to alpha-lipoprotein ratio, was found in disc gel electrophoresis. These results have been correlated to indicate differences in charge of alpha-lipoprotein components and in size of beta-lipoprotein components between these 2 breeds of horses.
