Topic:Animal Health
Animal Health encompasses a broad range of topics focused on maintaining and improving the well-being of equine species. This field addresses various aspects of horse care, including disease prevention, diagnosis, treatment, and management of health conditions. Key areas of interest include equine nutrition, vaccination protocols, parasite control, dental care, and the management of chronic conditions such as laminitis and colic. Additionally, animal health research in horses investigates the impact of exercise and training on physical health, the role of genetics in disease susceptibility, and the development of new therapeutic approaches. This page compiles peer-reviewed research studies and scholarly articles that explore the latest advancements, challenges, and best practices in preserving and enhancing the health of horses.
A method of ether anaesthesia in ponies. A method of inhalation anaesthesia using diethyl ether, following induction with thiopentone, is described in ponies. The high concentrations of ether needed to maintain anaesthesia were obtained by using a Marrett head in circle vaporizer. This methods would only be used in ponies, since the diameter of the tubing is too small for use on larger horses.
Veterinary aspects of doping. Doping can improve or impair performance and can be done either deliberately or accidentally. Accidental doping to win is the offence which most concerns the veterinary surgeon. The distinction between legitimate therapy and assisting an unfit horse to win a race by giving it a drug is a fine one. General guidelines are presented for the veterinary surgeon in practice.
Effect of imidocarb dipropionate and hemicastration on spermatogenesis in pony stallions. The effect of imidocarb dipropionate [3, 3' bis-(2-imidazolin-2-yl) carbanilide dipropionate] on spermatogenesis in 3 pony stallions was studied. The drug alone had no deleterious effect on spermatogenesis when given intramuscularly 4 times at a dosage level of 4 mg/kg at 72-hour intervals. Hemicastration, with or without subsequent drug treatment, caused almost complete cessation of spermatogenesis 30 days after the operation.
Surgical repair of cleft soft palate in the horse. A technique for the surgical repair of a cleft soft palate in the horse is described. A symphysiotomy approach was employed to repair the anterior end of the cleft palate, and the posterior part was approached via a pharyingotomy incision.
[Cochliatoxum periachtum Gassovsky, 1919, entodinimorphic Ciliate of the horse digestive tract]. The topography of Cochliatoxum periachtum is studied. The cuticle is very thick. The digestive, nuclear and excretory systems are located in the ectoplasm, they are not surrounded by the mesoplasm. The endoplasm is very large, it contains vegetable inclusions. By the features of its topography, this species is similar to some species belonging to the Family Ophryoscolescidae and, especially, to Eudiplodinium giganteum.
Liver fluke infection in horses and ponies. Thirty eight cases of Fasciola hepatica infection in horses with associated clinical signs are reported. A method of examining large amounts of faeces for fluke is described. A safe method of treatment for infected horses is given which involves oral medication with oxyclozanide at a dose rate of 15 ml/50 kg body weight.
Effects of fluoride on livestock. Animals normally ingest small amounts of fluorides in their diet with no adverse effect. An increased ingestion of fluoride can be harmful to animals, and grazing animals can be damaged by the consumption of high-fluoride vegetation. Cattle have been the species most commonly affected, and the symptoms of excessive fluoride ingestion in that species include; lesions in the developing dentition, skeletal lesions, lameness, chemical evidence of tissue fluoride ingestion in that species include: lesions in the developing take and decrease in production. The level of fluoride which can be tolerate...
Secular trends of annual morbidities of animal infectious diseases. Supposing two mathematical models, additive and multiplicative, the authors estimated the secular trends of annual morbidities (1949 approximately 1975) of twelve infectious diseases of domestic animals. For each diseases ten different trend curves were fitted. It was found that five regression equations, namely, those for bovine trichomoniasis, bovine tuberculosis, equine infectious anemia, pullorum disease in chickens, and foulbrood, gave the coefficient of determination of 97.9, 92.7, 91.0, 93.5, and 85.2%, respectively. Four of them were multiplicative, and the remaining one for equine inf...
Electron microscopic studies on equine infectious anemia virus (EIAV). Brief report. Morphological studies of EIAV reveal knobs on the surface of the particles, conically and tubularly shaped cores, budding particles with dense crescents directly underlying the plasma membrane, and distinct intracytoplasmic structures in infected cells.
Veterinary toxicology: the epidemiology of poisonings in domestic animals. Animals are constantly exposed to a wide variety of foreign chemicals, many of which are potentially toxic and some of which result in the clinical poisonings. Pesticides are applied on or around animals for the control of insects and rodents. These chemicals may be placed in areas without regard for accessibility to household pets and domestic livestock. Insecticides, herbicides, and fungicides are routinely and haphazardly applied to animal and environmental surfaces alike with apparent disregard for differences in absorptive capability. Fortunately, newer herbicides and fungicides are relat...
A review of the diagnosis and treatment of fluid and electrolyte disorders in the horse. Disturbances of fluid and electrolyte balance may occur in the horse as a consequence of many disease processes. Disorders may be classified into 3 main categories, primary water loss, mixed water and electrolyte depletion and acid base disturbances. This paper reviews the changes which occur with each type of disorder and discusses methods of diagnosis and assessment of such imbalances. The principles of treatment are described and the management of fluid replacement therapy in 3 of the disorders, mainly acute intestinal obstruction, inability to drink and diarrohea is discussed.
Human lymphocyte subpopulations: rosette formation with sheep, human and horse red blood cells. Rosette formation between human lymphocytes and horse red blood cells could be promoted by a low pH medium, overnight incubation and a temperature of 4 degrees C. The percent of sheep, horse and human rosette-forming cells in the peripheral blood were 71.7 +/- 1.8, 30.5 +/- 2.8 and 28.3 +/- 3.4 respectively. However, their percentages in thymuses were 97.1 +/- 1.1, 91.4 +/- 2.4 and 89.0 +/- 3.4. Using preparations of isolated subpopulations, it was observed that the horse and human red cell rosette-forming cells were probably also "early" sheep red cell rosette-forming cells. Rosette formation...
Strain differences in Echinococcus granulosus, with special reference to the status of equine hydatidosis in the United Kingdom. The genetics of speciation in the genus Echinococcus are briefly discussed. As the organism is a hermaphrodite and multiplies asexually in the larval stage, the genetic mechanism for the ready production of new strains is inherent in the life-cycle. Some biological, biochemical and nutritional differences between the horse and sheep strains are examined. The sheep strain may be grown to sexual maturity, in vitro, in a diphasic system; the horse strain fails to grow in such a system. Differences have also been demonstrated between the soluble proteins of the two strains. The sheep strain is inf...
Comparative study of the dorsal motor nucleus of the vagus nerve. Quantitative studies were made of cells in the dorsal motor nucleus of the vagus nerve in the horse, dog, cat, pig, sheep, goat, and calf. This nucleus was larger in ruminants than in nonruminants. Some cells in all parts of the nucleus supplied visceral structures in the head, cervical, thoracic, and abdominal regions; however, a definite topographic localization did exist within the nucleus. Eighty percent of the cells which supplied the abdominal viscera were in the rostral and rostral-middle regions. The cells which supplied the thoracic viscera were distributed almost equally within the r...
The activity of some nucleolytic enzymes in semen and in the secretion of the male reproductive tract. The activity of 5'-nucleotidase (EC 1.3.5), cyclic nucleotide phosphodiesterase (EC 2.1.4.17), non-specific phosphodiesterase (EC 3.1.4.1) and ribonuclease (EC 1.7.7.16)has been investigated in the seminal plasma of whole semen and in the secretions of the seminal vesicle, prostate and epididymis of the bull, boar, ram, stallion, jackass, rabbit and man. Bull seminal plasma showed the highest activity for 5'-nucleotidase, cyclic nucleotide phosphodiesterase and ribonuclease; in contrast, stallion and jackass semen were very poor in these enzymes. Ram, rabbit and boar seminal plasma showed inte...
