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.
Variation in arbovirus infection rates in species of birds sampled in a serological survey during an encephalitis epidemic in the Murray Valley of South-eastern Australia, February 1974. There was extensive and exuberant breeding of waterbirds before and during an epidemic of arboviral encephalitis in the Murray Valley of south eastern Australia in 1974. As estimated by haemagglutination inhibition tests on 432 bird sera collected between 4th and 13th February, 1974, infection with Murray Valley encephalitis virus, Kunjin virus and possibly other flaviviruses was concentrated in species of the Order Ciconiiformes (55% positive) and Pelecaniformes (41%), compared with only 5% in Anseriformes. Although Sindbis virus infections were also highest in these 2 Orders (56% and 46%, re...
Experimental equine aflatoxicosis. Adult male Shetland ponies, two per dose level, were given aflatoxin daily at levels of 0.3, 0.15, or 0.075 mg/kg. Signs of toxicosis included inappetence, depression, tremors, and terminal prostration. Deaths occurred at 12 and 16 days (0.3 mg/kg), 25 and 32 days (0.15 mg/kg), and 36 and 39 days (0.075 mg/kg). Prothrombin time, sulfabromophthalein clearance time, total plasma bilirubin, and icteric index increased markedly before death. Elevations in plasma activity of aspartate amino transferase (AST) were observed 1 to 4 days after the start of aflatoxin administration in the high dose grou...
Studies on Strongylus asini. I. Experimental infestation of equines. Infective larvae were harvested from a culture of eggs collected from adult Strongylus asini recovered from a free-ranging Burchell's zebra, Equus burchelli, in the Kruger National Park. Worm-free zebra, horse and donkey foals were successfully infested, but infestation failed in a mule foal. At slaughter, 117-125 days post-infestation, S. asini in their 4th moult were recovered from the liver and portal veins. This is the first report of successful experimental infestation of these hosts with S. asini.
On-line direct liquid introduction interface for micro-liquid chromatography/mass spectrometry: application to drug analysis. We describe an integrated micro-liquid chromatograph/mass spectrometer (micro-LC/MS) system capable of performing routine determinations for 1--10 ng of drugs and their metabolites extracted from biological fluids. The micro-LC is constructed from conventional "high-performance" liquid-chromatographic instrumentation by using commercially available components. The mass spectrometer is operated in the chemical ionization mode. The direct liquid introduction micro-LC/MS interface can be constructed from commercially available materials. Chromatographic and mass spectral results demonstrate the a...
Twinning in mares: A survey of veterinarians and analyses of theriogenology records. Responses of 22 veterinarians to a questionnaire and the records of three brood-mare farms were examined to obtain information on twinning. The incidence rates of multiple ovulations on the three farms were 9%, 11%, and 22%. The multiple ovulation rate was reduced 42-67% in foaling mares compared to barren and maiden mares. Multiple ovulations were significantly more frequent in Thoroughbreds (19%) than in Quarter Horses (9%) and Appaloosas (8%). Both the questionnaire and the farm records indicated a high degree of repeatability of multiple ovulations and twin pregnancies within mares and wit...
Multidirectional in vivo strain analysis of the equine radius and tibia during dynamic loading with and without a cast. Rosette strain gauges were applied to the equine radius and tibia. Three sites were examined on each bone on separate occasions (proximal metaphysis, middiaphysis, and distal metaphysis). At each site, 4 rosette gauges were applied around the bone (ie, cranial, caudal, medial, and lateral). Strain recordings were made while walking the horse with and without a full-limb plaster cast. The principal axis of tensile strain was on the craniolateral aspect of the radius. Distally, on the radius, the largest strains were torsional. The cast changed the principal axis of tensile strain on the radius ...
Phagocytosis and intracellular killing of the contagious equine metritis organism by equine neutrophils in serum. Equine neutrophils were combined with Haemophilus equigenitalis (contagious equine metritis organism; CEMO) or Escherichia coli in low- and high-antibody-titer serum to evaluate the neutrophils ability to phagocytize and kill these bacteria. More E. coli than CEMO were phagocytized at each time period. After 120 min in low-antibody-titer serum, 56.3% of the E. coli and 34.3% of the CEMO were phagocytized. A total of 45% of CEMO and 74.9% of E. coli were phagocytized by 120 min when neutrophils were in high-antibody-titer serum. More than 75% of the ingested E. coli and 90% of the ingested CEMO...
Microprocessor-based system for collection and storage of the equine vectorcardiogram. To evaluate the clinical application of a semiorthogonal lead system for use in the horse, an inexpensive means of recording and storing the ECG was required which would allow the subsequent vectorcardiographic analysis to be computerized. In investigating the various options for the system the basic requirements for the digitization of analogue data were reviewed and previous studies examined. The system subsequently developed used an 8080 microprocessor and a multichannel 8-bit analogue to digital converter. This unit was signal-level compatible with the laboratory recorder used in the study...
The effect of ethacrynic acid, bumetanide, frusemide, spironolactone and ADH on electrolyte excretion in ponies. The effect of ethacrynic acid, bumetanide, frusemide, spironolactone and anti-diuretic hormone (ADH) on the urinary and faecal excretion of water and electrolytes by ponies was studied. Ethacrynic acid, bumetanide, and frusemide given intravenously, increased urinary sodium excretion, and, excepting frusemide, decreased faecal sodium excretion. Given by stomach tube ethacrynic acid reduced urinary and faecal sodium. Bumetanide, given intravenously, spironolactone, frusemide and ADH increased urinary sodium and all except frusemide intravenously decreased faecal sodium regardless of route of ad...
Controlled tests of pastes of dichlorvos and thiabendazole against induced Strongyloides westeri infections in pony foals in 1973-1974. In 1973-1974, 4 controlled tests were performed in pony foals (n = 17) raised parasite-free and experimentally infected with Strongyloides westeri. Administration of infective larvae by stomach tube in 1 test resulted in low-grade infections and tended to invalidate the test. Intraoral and percutaneous (intra-aural) administration of larvae resulted in suitable test infections for 1 and 2 tests, respectively. A paste formulation of dichlorvos at 36.3 mg/kg of body weight removal from 4 ponies. Treatment of 4 the dosage rate of 44 mg/kg was consistently effective (greater than 99% to 100%) for ...
Dermatitis in horses and man caused by the straw itch mite. An episode of dermatitis in 12 horses and many animal handlers in the Veterinary Medical Teaching Hospital of the University of Florida was attributed to the straw itch mite, Pyemotes tritici. The mite was found in abundance alfalfa hay that recently had been delivered to the hospital. Papules were the most common cutaneous lesions, and these developed on areas of the body to which the mites had easiest access. The clinical course was self-limiting, remitting when the hay supply was depleted.
