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.
Anthelmintic efficacy of ivermectin given intramuscularly in horses. 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...
Fertility of frozen equine semen. Semen of 16 stallions collected by the fractionated method and frozen in liquid nitrogen was used to inseminate 175 mares of different ages and in various reproductive conditions. Pregnancy was recorded in 91 mares of which 72 delivered a foal. Pregnancy followed by resorption occurred in another 10 mares and 9 aborted. The best results were obtained in the young primiparous and in older mares inseminated in the oestrous cycle that followed the post-partum oestrus. Overall, 64% of mares became pregnant and 56% gave birth to a living foal. The highest occurrence of fetal death and resorption we...
Subcellular distribution of particle-associated enzymes in horse neutrophil leukocytes. The subcellular components of purified neutrophil leukocytes from horse blood were fractionated by isopyknic equilibration in sucrose and metrizamide gradients. Five classes of particles have been identified: dense azurophil granules containing the bulk of the lysosomal acid hydrolase and peroxidase activity (A); less dense particles, containing all the lysozyme activity, but not resolved from a second population of azurophils B, and particles of low density, biochemically characterized as a plasma membrane fraction (C). Isopyknic equilibration in sucrose disclosed a minor membrane fraction (D...
Primary structure of horse erythrocyte glycophorin HA. Its amino acid sequence has a unique homology with those of human and porcine erythrocyte glycophorins. 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...
Use of ultrasound echography for early diagnosis of single and twin pregnancy in the mare. 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...
The cryo-jaw, a clamp designed for in vitro rheology studies of horse digital flexor tendons. A clamp designed for holding tendons in force/elongation studies is described. No slippage occurred when tensile forces up to 13,800 N were applied to horses digital flexor tendons fixed in this clamp.
Bronchoscopy and cytological examination of bronchial secretions of horses with chronic obstructive pulmonary disease (COPD). On the basis of cytological similarities in chronic obstructive disease (COPD) in human beings and in horses during 1981 a total number of 144 horses with COPD were examined. Bronchial secretions were taken under endoscopic control and stained with a modified Hansel staining procedure. Whereas 26 horses did not exhibit signs of allergic reactions cytologically and 94 horses showed low amounts of eosinocytes and/or mast cells in their secretion; only the secretions of 24 horses (16,67%) were characterized by fairly high contents of these allergy associated cells and low numbers of neutrophilic ...
[Maduromycotic mycetoma in a horse]. A case of maduromycotic mycetoma (eumycetoma) in seven years old draught horse is described. The disease was localized in anal region and healed after surgical treatment. Attention is drawn to the necessity of distinguishing three types of mycosis in horses, characterized by the origin of tumor lesions - mycetomas, hyphomycosis and entomophthoromycosis - and information was gathered on their etiology and geographical occurrence. On the basis of the morphology of fungal elements traced in inflammated changed tissues and with regard to the existing findings on the origin of eumycetoma in animals...
Vitamin A profiles of equine serum and milk. Serum and milk samples from mares and serum samples from their foals were taken at parturition and on d 1, 2, 4, 7, 14 and 21 postpartum. The samples were assayed for retinyl (r.) palmitate, r. acetate and retinol by high performance liquid chromatography. Peak vitamin A activity in milk occurred 1 d postpartum and preceded by 3 d the maximum vitamin A activity in foal serum and the lowest vitamin A activity in the mare serum. Mare serum contained approximately a 65:35 ratio of retinol:r. palmitate and less than 1% r. acetate. Retinyl palmitate was the predominant form of vitamin A in milk unt...
Effect of adrenergic neurotransmitters upon the ejaculatory process in the stallion. Successful empirical treatment of 17 out of 24 stallions, which had failed to ejaculate after normal penile erection, intromission and friction, by chemical blockage of beta-receptors and additional stimulation of alpha-receptors led us to investigate stallions with normal ejaculatory patterns. In an initial experiment one adult half-bred stallion was injected with 4.88 mg noradrenaline hydrochloride (treatment A), 10 mg bunitrolol (treatment B = beta-receptor blockage) and a combination of treatment A and B. Investigations of the same stallion on dated occasions without treatment served as co...
Indirect hemagglutination test in equine infectious anemia. An indirect hemagglutination was developed for the diagnosis of equine infectious anemia using sheep red blood cells coated with group specific virus antigen which had been highly purified by affinity chromatography. The presence of indirect hemagglutination antibodies was demonstrated in horses with equine infectious anemia since the cells were specifically agglutinated by all the serum samples obtained from experimentally infected horses. Antibodies appeared within 35 days after inoculation, and development of which coincided well with that of precipitating and complement fixing antibodies. ...
Equine onchocerciasis: lesions in the nuchal ligament of midwestern U.S. horses. Nuchal ligaments from midwestern U.S. horses infected with adult Onchocerca sp. were studied. The prevalence of Onchocerca sp. infection in horses increased with age. Ten percent of horses less than one year old were infected, 28% of horses one to five years old, 48% of horses six to 15 years old, and 90% of horses over 16 years old. Lesions in Onchocerca sp.-infected nuchal ligaments varied with age of the horse. Horses less than five years old had few or no lesions, whereas most horses six to 15 years old had focal mineralization and granuloma formation around adult worms. In infected nuchal...
Subchondral cystic and related lesions affecting the equine pedal bone and stifle. 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 ...
Variation in cellular tropism between isolates of equine herpesvirus-1 in foals. 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...
Traumatic fractures of the equine hock: a report of 13 cases. 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...
Radiographic examination of the equine stifle. A radiographic technique is described for the equine stifle joint with the horse in the standing position or under general anaesthesia. The method with the animal anaesthetised in the dorsal recumbency and the leg extended was preferred because it gave greater flexibility with a better range of views and greatly reduced the safety hazards. In the standing position a useful practical tip for the lateral view was to raise and extent the limb caudally. This provides some flexion and ventral movement of the stifle allowing improved access for the cassette, a more accurate lateral view of the joint...
Results of concurrent bacteriological and cytological examinations of the endometrium of mares in routine stud farm practice 1978-1981. The results of 4024 concurrent endometrial swab and smear tests taken from maiden, barren and post-parturient mares during early oestrus, before coitus demonstrated the practical value of these tests in routine stud farm practice. The use of cytological examinations provided a more direct diagnostic test for acute endometritis and this increased the accuracy of interpretation of the bacteriological findings.
