Veterinary science and horses encompass the study and application of medical, surgical, and therapeutic practices to maintain and improve the health and welfare of equines. This field addresses a wide range of topics, including disease prevention, diagnosis, and treatment, as well as nutrition, reproduction, and behavior. Research in veterinary science for horses often involves understanding the pathophysiology of equine-specific diseases, developing advanced diagnostic techniques, and improving treatment protocols. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of veterinary science related to horses, providing insights into the latest advancements and methodologies in equine healthcare.
Silberzahn P, Quincey D, Rosier C, Leymarie P.Measurements every day or every other day showed that testosterone levels ranging from 15 to 70 pg/ml were higher at oestrus in 4 of the 6 mares studied. In these 4 mares, another testosterone peak occurred 11--13 days before the next oestrus either before (3 mares) or after the fall in progesterone levels.
Fujita K, Suzuki I, Ochiai J, Shinpo K, Inoue S, Saito H.We found that aloe extract contains a lectin-like substance which reacts with serum proteins of various animals. Furthermore, in human serum 2 proteins, alpha2-macroglobulin and alpha1-antitrypsin, were shown to be reactive with aloe extract.
Tizard IR, Harmeson J, Lai CH.The prevalence of seropositive reactions to Toxoplasma gondii was studied in farm animals, companion animals, wild rodents and birds. Of the animals tested, 17% of cattle, 65% of sheep, 45% of pigs, 9% of horses, 33% of dogs and 20% of cats were seropositive by the Sabin-Feldman dye test. In addition 11% of mice (Mus musculus), 5% of deer mice (Peromyscus), 3% of rats (Rattus norvegicus) and less than 2% of sparrows (Passer domestcus) were seropositive. All samples from short-tailed field mice (Microtus pennsylvanicus), squirrels (Sciurus carolinensis), chipmunks (Tamias striatus), meadow jump...
Odberg FO.The ability of 10 horses to hear frequencies between 14 and 25 Kc/s was tested. The horses appeared to perceive ultrasounds by showing either fright reactions or Pryer reflexes to all of the 12 frequencies. The highest frequencies were heard less by older animals, and elicited more reactions in geldings than in mares.
Grady GF, Maxfield HK, Hildreth SW, Timperi RJ, Gilfillan RF, Rosenau BJ, Francy DB, Calisher CH, Marcus LC, Madoff MA.Reappearance of eastern equine encephalitis (EEE) in Massachusetts residents in the 1970's provided an opportunity to assess the predictive value of data on rainfall, EEE in horses, and carriage of EEE virus (EEEV) by mosquitoes, factors which had been studied annually since the last EEE outbreak in 1955-1956. The cycle of multiple cases during 1973-1975 started in a second consecutive year of rainfall that exceeded the annual mean by more than 20 cm, conditions recapitulating the 1955-1956 experience. In 1973, widespread EEE fatalities in horses presaged human cases, another recapitulation of...
Kollias-Baker C.Analytic chemistry laboratories responding to the concerns of the industry over drug use and abuse in performance horses should continue to develop more sensitive methods of drug detection. The unwanted result of this increase in sensitivity is the detection of therapeutic medications days to weeks after administration. The adoption of decision or threshold concentrations for residues of nonpermitted medications should allow laboratories to focus their efforts on drugs of abuse in the performance horse industries and permit veterinarians to provide appropriate medical care to these equine athl...
Gilger BC, Brooks DE.This first IEOC symposium met its goals of gathering a group of leading equine ophthalmology clinicians and researchers to identify the challenges of the field. To facilitate collaboration, notes from round-table discussions, including the ideas and plans that were discussed are being complied and will be distributed to the attendees. Development of an IEOC membership organisation and website was discussed and supported by the group in an effort further to advance the science of equine ophthalmology. To present results from the collaborations made at this first IEOC meeting, an IEOC mini-sympo...
Nuchprayoon N, Ritruechai P, Watchararat K, Limroongruengrat W, Wongtawan T, Arya N.Hippotherapy in patients with neuromuscular dysfunction creates high focal pressure on the pony's back due to bareback riding and an asymmetrical riding position. This study aimed to investigate the acute effect of asymmetrical bareback riding on the pony's spinal kinematics, blood lactate, serum creatine kinase, heart rate, and temperament score. Eight ponies were selected, and they were walked on a treadmill for 45 min on each experimental day, including warm-up (5 min), weight-loading by mannequin (30 min), and cool-down (10 min) sessions. During the weight-loading session, three different ...
Dunnett M.N-alpha-Acetyl-L-carnosine (NAcCAR) in perchloric acid extracts of equine plasma was assayed by high-performance liquid chromatography on a 3 microns Hypersil ODS (150 x 4.6 mm I.D.) column eluted with 5 mM phosphoric acid-1 mM triethylamine, pH 2.58. NAcCAR was isolated by solid-phase extraction on Isolute PRS (propylsulphonyl) columns. The HPLC mean retention time for NAcCAR was 5.9 +/- 0.2 min. The recovery from plasma by solid-phase extraction was 93.9-99.7% and lower limit of detection in plasma was 0.18 microM. The normal NAcCAR concentration in equine plasma was 2.4 +/- 0.3 microM. The ...
Sonnichsen HV.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.
Garcia MC, Ginther OJ.Three experiments were performed to study the luteinizing hormone (LH) and ovulatory responses to various doses and methods of administration of gonadotropin-releasing hormone (GnRH) in estrous pony mares and the influence of estradiol-17beta (E2-17beta) on LH response to GnRH treatment. In experiment 1, single injections of synthetic GnRH were subcutaneously given to 5 groups of estrous (day 2) mares (3 mares/group) on a body weight basis as follows: group A--isotonic saline solution; group B--GnRH, 0.14 mug/kg; group C--GnRH, 0.28 mug/kg; group D--KGnRH, 0.59 mug/kg; and group E--GnRH, 2.37 ...
Dolente BA, Seco OM, Lewis ML.A 14-year-old horse was admitted to the veterinary hospital for treatment of tachycardia and lethargy. Initial diagnoses were ventricular tachycardia and renal dysfunction. During hospitalization other findings included fever, renal failure, hepatic failure, hypotension, and intermittent ventricular arrhythmias. Bacteriologic culture of 2 blood samples collected during febrile crises 7 days apart yielded Streptococcus mitis. These culture results along with other clinical and physical examination findings fulfill the criteria for a diagnosis of streptococcal toxic shock syndrome, previously de...
