Topic:Equine Diseases
Equine diseases encompass a wide range of health conditions that can affect horses, including infectious diseases, metabolic disorders, and genetic conditions. These diseases can impact the overall health, performance, and well-being of horses. Common equine diseases include equine influenza, equine herpesvirus, laminitis, and equine metabolic syndrome. Diagnosis and management of these diseases often require a combination of clinical evaluation, laboratory testing, and appropriate treatment strategies. This page gathers peer-reviewed research studies and scholarly articles that explore the etiology, pathophysiology, diagnosis, and treatment options for various equine diseases, providing valuable insights for veterinarians and researchers in the field.
[Preliminary performance test in saddle horses (author’s transl)]. The study of the literature on a preliminary performance test for saddle horses (stallions) is concerned with European countries. Interest is found to be increasing in the various countries. Performance of the test in the Netherlands (since 1966) is described and the various criteria of evaluation are discussed in detail. The intensity of selection based on this test is referred to. In 1974, it was 78 per cent in the Netherlands. Part of studies on the relationship between some results of testing are reviewed. The traction test shows a very low coefficient of correlation with the other parts o...
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.
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.
[Activity of serum gonadotropins in pregnant zebras and mares]. Blood was collected from 28 zebra mare (Equus burchellia antiquorum) immediately after being shot in the Kruger National Park. The serum was separated within two hours after collection and then stored at -15 degrees C for later assay. Of these, thirteen selected samples were tested for gonadotrophic activity. The stage of pregnancy was determined from a foetal growth curve. Blood samples from pregnant horse mares were collected by venipuncture. Nine mares were sampled. Seven blood samples at different stages of pregnancy were collected from one mare, four from another and only one sample each ...
Hereditary multiple exostosis. A comparative genetic evaluation in man and horses. Comparative studies are being conducted on hereditary multiple exostosis in man and the horse. In both, there is an unquestionable inheritance pattern of a typical single, dominant, autosomal gene. Those who carry the gene have a one-half chance of transmitting it to each offspring, whereas, those who do not carry the gene do not transmit this abnormality to their progeny. The lesions are clinically and histologically similar; no persistent chromosomal irregularities have been associated with the abnormality in either man or the horse and no single evidence of malignancy in either man or anima...
Oxygen affinity responses to 2,3-diphosphoglycerate, and methaemoglobin formation in horse and human haemoglobins. The oxygen affinities of horse and human haemoglobins were compared in the absence and presence of the allosteric effector 2,3-diphosphoglycerate (2,3-DPG). Horse haemoglobin solutions showed significantly smaller responses to the presence of 2,3-DPG, and this difference may be due to different amino acid substitutions at position NA2(2)beta. Horse haemoglobin solutions from erythrocytes containing different ratios of the two different haemoglobin types showed similar oxygen affinities in the absence and presence of 2,3-DPG. Horse haemoglobins in solution were found to autoxidise to methaemogl...
[Dexon, applicability in the horse (author’s transl)]. Dexon is a new, synthetic, absorbable suture material. Its applicability for suturing distally in the extremities of horses was tested in 65 cases. The indications included burried sutures as well as skin closure. It was concluded that the material can be used with advantage in cases traditionally sutured with catgut, vetafil or mersilene. It is technically a pleasant material and has further the advantage that it shall not be removed.
A field study of persistence of antibodies in California horses vaccinated against western, eastern, and Venezuelan equine encephalomyelitis. As a result of the continuing threat of Venezuelan equine encephalomyelitis (VEE), a study was made to determine if revaccination against VEE (TC-83 vaccine) was feasible and if revaccination could be incorporated into other routine vaccination practices. Of the horses given annual vaccination with bivalent western equine encephalomyelitis (WEE) and eastern equine encephalomyelitis (EEE) vaccine, 57% retained detectable serum-neutralizing (SN) antiboyd titers for VEE 18 months after the initial VEE vaccination was given. Of horses with no record of WEE-EEE vacinnation, 100% retained detectable...
Efficacy studies with three formulations of cambendazole in horses. Treatment with 3 formulations of cambendazole (paste, pellets, and suspension) was compared with thiabendazole treatment in 181 Quarter Horses (females and intact and altered males) of different ages in 2 experiments. The mean output of strongyle eggs, as measured by eggs per gram of feces (epg), was reduced by at least 95% by the 3 formulations of cambendazole compared with pretreatment epg and epg in simultaneously nonmedicated horses. Eggs of Parascaris equorum were seen in 19 of the younger horses in experiment I. Parascaris eggs were not seen in postmedication fecal samples from 14 horses...
Comparative electrophysiology and pharmacology of mammalian (including one marsupial) intercostal muscle biopsy preparations. Characteristics of minature end-plate potentials (MEPP) of isolated external intercostal muscle preparations of 7 mammalian species (dog, cat, pig, horse, cow, and goat) including 1 marsupial (opossum, Didelphis marsupialis) were determined with intracellular microelectrodes. Mean amplitude (+/- standard error of MEPP for all species was 0.60 +/- 0.06 mV, and the range was 0.28 mV (opossum) to 1.07 mV (pig). Amplitude was inversely correlated (P less than 0.01) with muscle fiber diameter which ranged from 93 mum (opossum) to 51 mum (pig). Mean values for rise time, half-decay time, and frequen...
The equine practice laboratory. The authors discuss the value of a practice laboratory to the equine clinician and its priorities. Laboratory examinations of particular value are described in relation to their clinical application. The need to establish normal values according to laboratory and horse population is stressed. Tables of normal parameters related to age groups of horses in the authors' practice are presented.
Empyema of the equine paranasal sinuses. A survey of 28 cases of chronic purulent infection of the sinuses in the horse showed a relationship between incidence and age, and a probable relationship with breed. Dental disease was apparently the cause of half the cases. The conventional treatment of trephination followed by irrigation with antiseptic solutions resulted in freedom from recurrence of the disease for over 1 year in 17 of the 28 horses. Antibiotic therapy appears to be useless in chronic empyema. The prognosis is adversely affected by the development of facial swelling, a sign seen usually only in long-standing cases.
Gonadal dysgenesis in the mare. Five phenotypically normal but infertile mares were studied; four had karyotypes of 63XO, and one was a 25,64XX/13,63XO mosaic. The mares exhibited small uteri and has small ovaries that lacked germ cells and consisted primarily of undifferentiated ovarian stroma. These cases demonstrate that chromosome analysis is an important technique for the diagnosis of some forms of equine infertility.
Abnormalities of mating behaviour in domestic stallions. Experimental and clinical observations were made to treat abnormal sexual behaviour. The most common cause of abnormality was mismanagement of the animal; over-use and rough treatment at service and too-frequent ejaculation during winter had a detrimental effect on the behaviour of young stallions. Pain due to injury incurred at copulation or when associated with mounting attempts was also a common cause of impotence. Most impotent stallions responded well to re-training and recovery can be achieved without pharmacological treatment in most cases.
