Veterinary care in horses encompasses the medical and preventive measures taken to maintain and improve the health and well-being of equine patients. It includes a wide range of practices such as routine health examinations, vaccinations, dental care, parasite control, and management of injuries and diseases. Veterinary care also involves diagnostic procedures, surgical interventions, and therapeutic treatments tailored to the specific needs of horses. This page gathers peer-reviewed research studies and scholarly articles that explore various aspects of equine veterinary care, including advancements in diagnostic techniques, treatment protocols, and health management strategies to support the well-being and performance of horses.
Jakovljevic S, Gibbs C, Yeats JJ.The clinical features, radiographic findings, management and outcome in 13 cases of traumatic fracture of the hock joint are reported. The principal fracture sites were the distal tibial malleoli (5 cases), the fibular tarsal bone (4 cases), the tibial tarsal bone (3 cases) and the proximal end of metatarsal IV (one case). An additional small chip fracture of the central tarsal was noted in 2 cases. Three horses were destroyed immediately after diagnosis, 2 failed to recover following surgical intervention and one remained lame and was destroyed after 3 months' rest. Seven horses recovered com...
Goulden BE, Anderson LG.During the years 1971-1979, 127 horses with left laryngeal hemiplegia were studied. The physical characteristics and clinical signs observed in this study were recorded in Part I and Part II of ths series of papers. Of these 127 horses, 81 were treated by the laryngoplasty procedure. Complications of surgery are described and the effects of the operation on respiratory noise and performance are evaluated. In 54.8% of horses the chronic respiratory noise observed during exercise was apparently diminished or eliminated post-operatively. The performance of 44% of horses was apparently improved af...
Kotoński B.The purification of alpha-1,4-1,4-glucosyltransferase from the equine serum is presented. Ion-exchange chromatography on DE-11, DE-32 and CM-32 celluloses was applied in the successive steps of isolation. Gel-filtration on Bio-Gel P-200 was the last step of purification; it gave the protein which was homogeneous on disc polyacrylamide gel electrophoresis. The purification degree was of the order 2100 at about 40% yield.
Murayama JI, Tomita M, Hamada A.The complete amino acid sequence of the major sialoglycoproteins of horse erythrocyte membranes, glycophorin HA, was determined by manual sequencing methods, using tryptic, chymotryptic, and cyanogen bromide fragments. Glycophorin HA is a polypeptide chain of 120 amino acid residues and contains 10 oligosaccharide units attached to the amino-terminal side of the molecule. Its amino terminus is pyroglutamic acid. All of the oligosaccharides are linked O-glycosidically to threonine or serine residues. The amino acid sequence is consistent with the transmembrane orientation of glycophorins. There...
Verschooten F, De Moor A.Twenty-nine horses were examined over a period of 8 years and found to have cystic lesions in the stifle (14 cases) or pedal bone (15 cases). The lesions are described and illustrated with radiographs. In the stifle 12 lesions were found on the femoral condyles (11 medially and one laterally) and 10 were typical subchondral cysts. One lesion was observed in the tibia and 3 in the patella. Bone cysts wee found unilaterally in the pedal bone (14 in the forelimbs and one in the hindlimb). All but 2 of the horses with lesions in the stifle or pedal bone were lame. The only treatment was rest. For ...
Simpson DJ, Greenwood RE, Ricketts SW, Rossdale PD, Sanderson M, Allen WR.In 1981 a trial was conducted on 6 Newmarket Thoroughbred stud farms into the use of real-time ultrasound echography (scanning) as an aid to the early diagnosis of pregnancy in the mare. The procedure was found to be practicable and interpretation of the findings was relatively straightforward. Pregnancy was positively diagnosed from as early as 14 days after ovulation and a number of twin pregnancies were recognized, some in which the conceptuses were situated in separate horns of the uterus but an almost equal number in which the conceptuses were together in the same horn. It was concluded t...
Dzongowska-Dzongu T, Kotoński B, Hutny J.Alpha-1,4 leads to 1,4-glucosyltransferase preparations from horse muscles and serum were studied. The enzyme proteins from both tissues are very similar. Both proteins have a molecular weight of 240 000 and consist of four subunits of 60 000 daltons each. pH 5,0 is optimal for the activity. Only substrates with alpha-1, 4-linkages can serve as glucosyl donors for transferase reactions. Km values for both enzymes differ very slightly. At low substrate concentrations the hydrolytic activity can be found in addition to transferase reactions. At the concentration of the substrate higher than 40 m...
Patel JR, Edington N, Mumford JA.Subtype-1 isolates of Equine herpesvirus-1 (EHV-1) from a quadriplegic horse and from an aborted foetus were compared with each other and with a subtype-2 respiratory isolate. All 3 isolates were detected in the epithelium and macrophages of the respiratory tract. Both the paresis and foetal subtype-1 isolates replicated in the epithelium of the ileum and this correlated with the recovery of virus from faeces in vivo. The paresis subtype-1 isolate also had a predelection for vascular endothelial cells, particularly in the nasal mucosa, but also in the lungs, central nervous system, adrenal and...
Greet TR.Radiological features of the oesophagus of 7 normal horses and 13 with oesophageal lesions are described. The use of barium sulphate as a contrast agent and the techniqes of its administration are discussed. It is suggested that chronic intermittent oesophageal impaction with food material was a predisposing factor in the development of a localised oesophageal dilation in 3 horses and that one other probably resulted from an injury. A similar dilatation was seen which resulted from oesophageal constriction by a vascular ring. Megaoesophagus was seen in 2 ponies associated with grass sickness a...
Pascoe PJ.A 16 year old Thoroughbred mare was presented to the Ontario Veterinary College because of an acute episode of colic. An exploratory laparotomy was performed and a neurofibroma was identified and successfully removed from the small colon. The clinical and pathological features of this case are discussed.
DiPietro JA, Todd KS, Lock TF, McPherron TA.The anthelmintic activity of ivermectin was evaluated in 18 female horses with naturally acquired parasitic infections. Horses were treated once (IM) with vehicle only (n = 6), 200 microgram/kg of body weight (n = 6), and 300 microgram/kg (n = 6). Efficacy of both dosages of ivermectin was greater than 99% against Gasterophilus spp, 100% against Trichostrongylus axei, Habronema muscae, H majus, and Draschia megastoma, 98% to 99% against adult cyathostomes, 86% to 97% against 4th-stage cyathostomes, and 100% against adult large strongyles. Although ivermectin was incomplete in its activity agai...
Dixon PM, McPherson EA, Muir A.A trotter mare with a history of poor performance was found to have methaemoglobinaemia and haemolytic anaemia associated with decreased erythrocyte glutathione reductase and glutathione levels. The mare's dam, which also had a history of poor performance, was subsequently found to be similarly affected.
Frey HH, Fitzek A, Wintzer HJ, Baumgärtel E.Use of the potent, high-ceiling diuretic bumetanide made it possible to obtain urinary samples for dope testing of trotters within the 1st hour after the race. The drug was injected intravenously at a dose level of 10 mug/kg during the cold season of the year, but on warm days, a dose of 20 mug/kg was more reliable. These doses did not produce any side-effects and did not interfere with the detection of doping drugs, since bumetanide is not metabolized to a detectable degree and the unchanged drug appears only in extracts from acidic urine. By enhancing the clearance of drugs used for doping, ...
Grabner A.Mycosis of the guttural pouches is a sporadic disease characterized by diphtheroid-necrotizing inflammation, and is caused by different fungal species, mainly by Aspergillus spp., Penicillium spp. and Candida spp. Highest incidence is during summer in stable horses. Proper diagnosis often requires--besides detection by mycological techniques--histological examination of tissue obtained by bioptic endoscopy. Prognosis is hopeless in late stages of the infection because of the erosion of the carotid artery or accompanied by the fatal complications of a not reparable cranial nerve damage also in ...
Cunha AP, Bello AC, Leite RC, Bastianetto E, Ribeiro AC, Freitas CM, Oliveira PR.The aim of this study was to verify the efficiency of a strategic control program of Amblyomma cajennense in horses under field conditions. Acaricide treatments were applied at seven days intervals and divided in two series, the first one beginning in April 2004 (eight treatments), and the second one beginning in July 2004 (five treatments), aiming to control larvae and nymphs of the tick. A pyrethroid chemical base cypermethrin 0.015% was used for spraying the horses. There was a reduction of 44.85% in the adults infestation of the tick in the period of October 2004 to March 2005, and 59.74%,...
Verschooten F, Picavet TM.Desmitis of the fetlock annular ligament was diagnosed in 30 horses during a period of eight years. Most of the horses had been lame for a prolonged period and had chronically distended digital flexor tendon sheaths. Air tendograms demonstrated thickened palmar or plantar annular ligaments. In 25 horses the ligament was cut longitudinally; of these, 16 horses returned to full work without any difficulty and one became sound after a second operation. Follow up time varied from three months to seven-and-a-half years. None of the five untreated horses returned to work.
Booth TM, Butson RJ, Clegg PD, Schramme MC, Smith RK.Gentamicin-impregnated polymethylmethacrylate beads were used to treat infective arthritis in the small tarsal joints of 11 severely lame horses. Under general anaesthesia, between five and 10 beads were placed into a 7 to 8 mm tract drilled across the affected joint and, in all except one horse, they were left in place for 14 days. Two of the horses were euthanased for reasons other than persistent tarsal joint sepsis, but the other nine survived and seven of them returned to their previous level of athletic performance.
Marteniuk JV, Carleton CL, Lloyd JW, Shea ME.To determine whether sex of fetus, sire, month of conception, or year of foaling was associated with duration of gestation in mares. Methods: Epidemiologic retrospective cohort study. Methods: 500 foalings for 296 Standardbred mares. Methods: Data for reproductive events from 1986 to 1992 were analyzed. Analyses were conducted to determine whether duration of gestation was associated with sex of fetus, sire, month of conception, or year of foaling. Results: Mean duration of gestation was 343.3 days and was significantly greater for colt fetuses (344.4 days) than for filly fetuses (342.2 days)....
