Equine Science encompasses the study of horses and their management, health, and performance. This field integrates various scientific disciplines such as biology, genetics, nutrition, physiology, and veterinary medicine to understand and improve the well-being and capabilities of horses. Areas of focus include equine anatomy, reproduction, behavior, and disease prevention. Research in equine science aims to enhance horse care, optimize training and performance, and address health challenges. This page compiles peer-reviewed research studies and scholarly articles that explore the diverse aspects of equine science, providing insights into the latest advancements and methodologies in the field.
Vigroux P, Candau M, Ruckebusch Y.Electrical spiking activity of the caecum is increased eight-fold and the rate of passage of digesta is increased four-fold when the volume of caecal contents is doubled. The role of caecal motility in regulating the volume of caecal contents is discussed.
Johnson JE, Ryan GD.Soft tissue lesions are often secondary to equine carpal injury. The clinical and pathological nature of soft tissue changes following carpal trauma are varied. This report describes a case of intersynovial fistula between the radial carpal joint and the common digital extensor tendon sheath. The differential diagnosis and pathological features of equine soft tissue carpal injuries are discussed.
Allen PZ, Dalton EJ.Donkey IgGa was isolated in purified form from normal and immune donkey sera by column chromatography on DEAE-cellulose. Isolated donkey IgGa and mixtures of (IgGa+IgGb) were used as antigens to prepare rabbit reagents specific for equine IgGa or IgGb. Antibodies present in sera obtained from a single donkey at various times during the course of hyperimmunization with BSA were isolated by immuno-adsorption. The class or subclass of immunoglobulins present among isolated, donkey anti-BSA antibodies was determined by use of specific rabbit anti-equine immunoglobulin reagents. The homologues of h...
Zakopal J, Kubícek K, Koprivová M, Kepková K.A study was performed to examine microclimate in 14 stables belonging to 10 horsemen's teams and clubs; five of these houses were new-built. In five race-horse stables housing 16 horses each, on an average, where the optimum air temperature ranged from 10 degrees C to 12 degrees C, measurements and examinations were performed in the winter period and the following results were obtained: space per 1 horse housed 42.9 plus or minus 8.7 m-3, relative air humidity 74.3 plus or minus 3.8%, CO2 concentration 0.175 plus or minus 0.027%, NH3 concentration 0.00135 plus or minus 0.00044%. A large majori...
Evans JH, Barbenel JC.Tendon normally fulfills its primary role as a flexible force transmitting element very effectively and yet failure of this passive tissue leads to great disability. As a connective tissue its structure is relatively simple and the peculiar helical arrangement of collagen fibres confers highly non-linear as well as time-dependent mechanical properties. Functional significance cannot be attributed to any facet of mechanical response until the physiological pattern of loading is established. In particular the rate of deformation and the minimum force experienced by tendon in normal locomotion ha...
Dorn CR, Garner HE, Coffman JR, Hahn AW, Tritschler LG.The characteristics of a series of equine laminitis cases were compared with that of other Equidae examined at the University of Missouri Veterinary Hospital and Clinic during May, 1965 through December, 1971. The model age for ponies with laminitis was 7-9 years and for all other cases the model age was 4-6 years. Also the predominant age for mares was 4-6 years and for males was 7-9 years. After controlling for age and breed differences, there were significantly fewer castrated males among the affected males than expected (P small than 0.02), indicating that hormonal factors may play a role ...
Fontaine M, Fontaine M.In the first part of this paper the conditions for a specific titration of antibodies against the neuraminidase (N) of each of the two horse virus subtypes are defined. The antigens used are: the H72Neq 1 recombining agent to measure the anti Neq1 antibodies and the A/Duck/Ukraine/63 strain for the anti Neq2 antibodies. The immunity response to neuraminidase appears after the natural disease; this response is studied in two foci, one due to a virus belonging to the A equi I subtype (Loire 73 strain), the other to a virus of the A equi 2 subtype (SHN 73 strain). The kinetics of apparition of an...
Tischner M, Kosiniak K, Bielański W.The emission of stallion semen was studied with the aid of
an `open' Krak\l=o'\w-72Model artificial vagina. The pattern of mating
behaviour was constant in all copulations observed : a mean number of
seven intravaginal thrusts was required to elicit ejaculation. The
pressure within the vestibule of the artificial vagina averaged 66 mmHg
at the beginning of copulation, 142 mmHg just before ejaculation, and
70 mmHg during the emission of semen. Emission appeared to be a more
variable process. Five to ten jets were observed; the mean number was
eight. The early jets occurred under high pr...
Stromberg BR, Norberg AW.Forty-six horses were submitted to a thermographic screening test. Forty showed a reasonably uniform IR-emission pattern of the coronary corium of the forelegs. The 133Xe-disappearance rate was studied in six of these horses, and the wash-out curves were found to be almost similar between the two extremities of each horse, except for slight differences between individual horses. Six horses showed a different IR pattern. Three had both coronary bands, and three had one coronary band, showing lower temperature. All cases with less warm coronary bands showed a low 133Xe-disappearance rate at rest...
Witherspoon MD.Serial photography of the ovary of a mare by periodic surgical exteriorization of the ovary and peritonescopy in situ revealed that the ovulatory fossa is the site of ovulation in this species.
Kydd J, Nielsen M, Waller A.Julia Kydd, Martin Nielsen and Andrew Waller highlight some of the key presentations given at last year's 11th International Equine Infectious Diseases Conference, which was held virtually.
Khittoo G, Vermette L, Nappert G, Lariviere N.In mammalian species studied previously, pepsinogen consisted of biochemically different groups of isozymogens. By use of gel filtration chromatography and electrophoresis, we isolated a predominant pepsinogen from the gastric mucosa of a horse. Peptide mapping with V8 protease revealed differences with its porcine homologue. However, porcine and equine pepsinogens, when activated to pepsin, had a similar pattern of activity when hemoglobin was used as substrate. Those results suggest that differences must exist in the primary structure of the pepsinogens of the 2 species.
Kim Y, Seo C, Oh S, Kwak J, Jung S, Sin E, Kim H, Ji M, Lee HS, Park HJ, Lee G, Yu J, Kim M, Lee W, Paik MJ.The authors have retracted this article [1] because after publication they became aware that the equine urine samples analysed for loxoprofen in this study were in fact equine plasma samples. Therefore the results and conclusions of this article cannot be relied upon. All authors agree to this retraction.
McKinney AR, Ridley DD, Suann CJ.The phase I and phase II metabolism of the anabolic steroid methandrostenolone was investigated following oral administration to a standardbred gelding. In the phase I study, metabolites were isolated from the urine by solid-phase extraction, deconjugated by acid catalysed methanolysis and converted to their O-methyloxime trimethylsilyl derivatives. GC-MS analysis indicated the major metabolic processes to be sequential reduction of the A-ring and hydroxylation at C6 and C16. In the phase II study, unconjugated, beta-glucuronidated and sulfated metabolites were fractionated and deconjugated us...
