Topic:Veterinary Care
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.
Clinical toxicosis and erythrocyte cholinesterase inhibition of trichlorfon combined with mebendazole in horses. Thirty adult horses were used to compare the toxicity and cholinesterase (ChE) inhibition of various dosages of a combination anthelmintic, trichlorfon + mebendazole. Single oral doses of up to 5 times the effective dosage (39.7 mg of trichlorfon and 8.8 mg of mebendazole/kg of body weight) did not result in deaths. Horses given a placebo and horses treated at the recommended dosage rate showed few or no side effects, whereas horses given higher dosages showed dosage-related increases in the severity of clinical signs of organophosphate toxicosis. Dosage-related inhibition of erythrocyte ChE a...
The heart score theory in the racehorse. During the last three decades in Australia and New Zealand the heart score theory has been used in the cardiovascular assessment of racehorses in training (Steel 1957, 1963, 1966-67; Irvine 1964, 1966; Stewart and Steel 1970; Steel and Stewart 1972, 1974). In particular the heart score has been of value as one of several factors employed in assessing the potential of the horse for different types of racing. More recently, studies indicating the heritability of heart score and its possible sex-linkage (Steel et al 1977) have suggested its use also as one of several criteria for selection in rac...
Equine laryngeal hemiplegia, Part I: Physical characteristics of affected animals. Various physical characteristics of horses affected with laryngeal hemiplegia were studied. Appropriate comparisons were made with the populations from which the affected animals were obtained. Statistical evidence is presented which supports the widely held clinical impression that heavy, young, male animals are most susceptible to the disease.
Habronemic blepharoconjunctivitis in horses. Habronemic blepharoconjunctivitis was characterized clinically by raised yellow gritty plaques in the palpebral and bulbar conjunctivae. Lid granulomas and blepharitis were observed in some cases. On histologic examination, mast cells, eosinophils, and collagenolysis was found in most sections, but if only one section was examined an erroneous diagnosis of mastocytosis could have been made. Treatment consisted of larvicidal mixtures for lid lesions and organophosphate ophthalmic drops along with corticosteroids for the conjunctivitis. If the cornea was damaged by the gritty conjunctival plaque...
Recovery of helminths postmortem from equines. I. Parasites in arteries, subperitoneum, liver and lungs. The entire gastro-intestinal tract and viscera of the abdomen and thorax, including the heart, aorta and its branches to the viscera, are removed from the carcass. All the branches of the aorta, with the exception of the A. gastrica sinistra, are dissected from the intestinal tract, and subsequently each branch is isolated from the mesentery, fat, pancreas, kidneys, etc. Usually, the A. ileocolica is grossly enlarged due to chronic arteritis with thrombus formation caused by 4th stage larvae, 4th moult and 5th stage Strongylus vulgaris. Descriptions of methods to examine the subperitoneal tiss...
Behavioral and cardiorespiratory responses to 4-aminopyridine in healthy awake horses. 4-Aminopyridine was administered in incremental IV doses to healthy horses to evaluate cardiorespiratory and behavioral effects. Doses of 100 micrograms/kg produced apparent sensory discomfort, manifested by wiggling or curling of the lips and tongue, arching or stretching the neck, snorting, squealing, and coughing. At cumulative dosages of 300 to 500 micrograms/kg, muscle tremors, a stilted gait, and signs of excitement occurred. Once signs of excitement occurred, additional administration of 4-aminopyridine resulted in prolonged excitement consisting of severe muscle tremors and exaggerated...
[Prevalence of lungworm D. arnfieldi (Cobbold 1884) in donkeys in Denmark and in horses in herds together with donkeys (author’s transl)]. During a 5 months' period from January to May 1981 faecal samples of 176 donkeys from 59 herds all over the country were examined at the Institute of internal medicine, The Royal Veterinary and Agricultural University, Copenhagen. In addition, the investigation also included 106 horses from 30 of the donkey herds and 34 horses hospitalized with symptoms of dyspnoea and chronic coughing. In all, 87.5% of the donkeys were shown to excrete D. arnfieldi larvae, often in very high numbers, and the larval excretion was the only symptom of lungworm infection. There was no significant correlation betw...
Stability of viability and immunizing potency of lyophilized, modified equine arteritis live-virus vaccine. The Bucyrus strain of equine arteritis virus, previously modified to avirulence and vaccinal virus by 131 serial passages in primary cell cultures of horse kidney followed by 111 passages in primary cell cultures of rabbit kidney, was further passaged in cultures of the E. Derm (NBL-6) cell line, a continuous diploid cell line. Pools of the 16th and 25th passages of the virus in this last equine dermal cell line were lyophilized and stored in lots at 37 C, 23 to 28 C, 4C, and -20 C. The viability of the vaccinal virus deteriorated rapidly during storage at 37 C and at 23 to 28 C, but was relat...
Actinobacillus lignieresii infection after a horse bite. Perforation is the most serious complication of fibreoptic endoscopy.1
The commonest site of perforation during upper gastrointestinal
endoscopy is the oesophagus,' but predisposing factors have not been
fully documented. We report a retrospective survey of major endoscopy
units in the United Kingdom and attempt to identify the factors associated with oesophageal perforation.
Distal intertarsal and tarsometatarsal joints in the horse: communication and injection sites. One hundred three equine hocks, obtained from the postmortem room, were used to study the communication and injection of material into the distal intertarsal and tarsometatarsal joints. Excluding the hocks with fused central and 3rd tarsal bones, in 8.3% of hocks injected with low (clinical) pressure and in 23.8% injected with high pressure, the distal intertarsal and tarsometatarsal joints communicated by dissection of the material through 2 internal spaces: the tarsal canal and the space between the combined tarsal bones 1 and 2 tarsal bone 3. A "pop" sometimes felt when high pressure was us...
Surgical management of uterine torsion in the mare: a review of 26 cases. Uterine torsion was diagnosed in 26 mares of various breeds. The mean duration of gestation was 9.6 months. The most common clinical history was intermittent unresponsive colic of varying duration. Diagnosis of uterine torsion was confirmed by rectal palpation, and surgical correction was achieved in most cases by standing flank laparotomy and manual repositioning of the gravid uterus. Recumbent laparotomy was used only if the mare was intractable, the uterus was ruptured, or hysterotomy was indicated. Of 20 foals determined to be alive during surgery, 14 (70%) were subsequently born alive.
Uterine prolapse in a mare. A prolapsed uterus in a mare and the techniques to successfully replace the organ and prevent complications such as shock, laminitis and metritis are described.
