Topic:Horses
"Horses" is a broad topic that encompasses various aspects of equine biology, behavior, and management. This category includes studies on the anatomy, physiology, and genetics of horses, as well as their behavior, nutrition, and care. Research in this area may also cover the historical and cultural significance of horses, their roles in agriculture, sport, and therapy, and the challenges associated with their conservation and welfare. The page aggregates peer-reviewed research articles and scholarly studies that explore the multifaceted relationships between humans and horses, examining both scientific and socio-economic perspectives.
Determination of total and ultrafilterable calcium and magnesium in normal equine serum. Total and ultrafilterable calcium (Ca) and magnesium (Mg) values were determined for Shetland pony stallions, stallions, and pregnant and diestrous mares, using a simple, inexpensive, quick procedure to obtain an ultrafiltrate of serum. There was no significant difference between horses and ponies, between stallions and mares, or between pregnant and nonpregnant mares. The percentage of total serum Ca that was ultrafilterable was 63.4+/-1.7 for horses and 64.8+/-2.2 for ponies. The percentage of total serum Mg that was ultrafilterable was 75.6+/-1.5 for horses and 77.0+/-1.7 for ponies. Total ...
Evaluation of xylazine and ketamine hydrochloride for anesthesia in horses. The cardiopulmonary effects resulting from the combination of xylazine and ketamine hydrochloride were evaluated in the adult horse. Xylazine (1.1 mg mg/kg) administered intravenously prior to or simultaneously with ketamine hydrochloride (2.2 mg/kg; intravenous) provided excellent analgesia and light anesthesia in all horses. Cardiac output, arterial blood pressure, pulmonary arterial pressure, central venous pressure, and pulmonary arterial wedge pressure remained within normal limits for the adult horse. Evidence of respiratory acidosis developed with time during the anesthetic period. Indu...
Observations on small metacarpal and metatarsal fractures with or without associated suspensory desmitis in Standardbred horses. ALTHOUGH METACARPAL TI-IV and metatarsal II-IV (MC II-IV, MT II-IV) fractures are frequent in horses and surgical intervention routine, a review of the current literature revealed little information about this subject. The authors have found only two complete accounts of this problem (1, 6). The incidence of suspensory desmitis has been previously reported (3), but we find no previous correla-tion of MC II-IV, MT II-IV fractures with suspensory, desmitis. On these bases, a re-trospective study was conducted. At Purdue University from 1967 through 1974, 50 Standardbred horses underwent sur-gery...
Cardiac Arrhythmias in the horse. Electrocardiograms were obtained from normal horses and from horses with cardiac or other organic disease that affected the cardiac rhythm. Tracings were obtained from a base-apex bipolar monitor lead, with the negative electrode attached to the skin in the right jugular furrow and the positive electrode attached to the skin on the ventral medline, beneath the apex of the heart. Each arrhythmia was discussed relative to importance and probable cause.
Navicular disease in the horse: risk factors, radiographic changes, and response to therapy. In a retrospective study, 74 horses met defined historical and clinical features indicative of navicular disease. Most of the affected horses were 4 to 9 years old. Males had a greater risk of navicular disease than females, geldings had a greater risk than stallions, and Quarter Horses had a greater risk than other breeds. Diagnostic radiographic changes were found in 42 of 70 horses examined. The distribution of diagnostic radiographic changes between the right and left fron feet was equal. There was no correlation between the finding of diagnostic radiographic changes and the horse's respon...
Acupuncture: clinical trials in the horse. A discussion of the merits of acupuncture therapy and a review of experiments that support the neurogenic mediation of acupuncture are presented. Case reports are included as examples of the therapeutic value of acupuncture in treatment of intestinal and musculoskeletal disorders in the horse. Statistical importance cannot be credited to the clinical experiences reported here because of the small number of cases. Hopefully, the clinical success reported will encourage continued investigation of the clinical efficacy and adjunctive value of acupuncture in the veterinary profession.
Equine degenerative myeloencephalopathy. Five horses of mixed breeding and 1 zebra with symmetric tetraparesis and ataxia were studied. There were 2 females and 4 males. Signs of illness were first noticed from birth to 12 months of age. Clinical and pathologic studies were performed when the animals were 4 to 24 months old. Two of the horses were related. All of the subjects had diffuse degenerative myeloencephalopathy. The degeneration was most pronounced in thoracic segments of the spinal cord. Ventral and dorsolateral funiculi were most severely affected. Axonal swelling and abnormal neuronal cell bodies were seen in the gray mat...
Pleuritis and pleural effusion in the horse: a study of 37 cases. Pleural effusion in 37 horses, including 15 acutely affected and 22 chronically affected, was found to be due to a variety of causes, including lymphocarcoma, pulmonary granulomas, coccidioidomycosis, equine infectious anemia, pulmonary abscesses, chronic pneumonia, and primary septic pleural effusion. Age, breed, or sex predilection was not found. Horses with chronic disease had weight loss, increased respiratory rate, dull respiratory sounds in the ventral portion of the thorax, and varying degrees of anorexia. Many horses were anemic. Those acutely affected had respiratory distress or signs...
Portal vein anomaly and hepatic encephalopathy in a horse. Periodic episodes of diffuse central nervous system disease occurred in a yearling Thoroughbred gelding that had a history of frequent respiratory tract disease and stunted growth. Hepatic encephalopathy was diagnosed on the basis of history, clinical signs, prolonged bromsulphalein clearance, and increased blood ammonia content. Because of the poor prognosis and recurrent clinical signs the horse was euthanatized. Necropsy revealed an arteriovenous anomaly and thrombosis of the portal vein. Histologically, there was diffuse primary astrocytosis of the brain.

Selective immunoglobulin M deficiency in foals. Selective immunoglobulin M deficiency was diagnosed in 5 foals, on the basis of reduced serum immunoglobulin M concentrations (more than 2 standard deviations below the normal mean). All 5 foals had clinical signs or lesions involving the respiratory tract. Lkebsiella sp was isolated from joint fluids, bronchial lymph nodes, or tracheal washings from the 3 foals in which such samples were available for microbiologic evaluation.
