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.
Proliferation and morphology of chick embryo cells cultured in the presence of horse serum and hemoglobin. We have shown previously that hemoglobin greatly stimulates chick embryo cell proliferation in Eagle's minimal essential medium supplemented with horse serum. In the present study we compared the effects of horse serum plus 10 micrometers hemoglobin to those of fetal bovine serum on subcultures of chick embryo cells serially propagated at high cell densities. The cells became elongated in the presence of fetal bovine serum and their rate of proliferation progressively decreased, whereas they became polygonal in the presence of horse serum plus hemoglobin and proliferated well in successive cel...
The pH/log PCO2 buffer curve of horse blood. Samples of jugular venous blood from six horses were equilibrated with six oxygen and carbon dioxide gas mixtures of PCO2 between 28 and 54 mm Hg. In all six samples the correlations between the pH and the log PCO2 values were linear and highly significant, with r in all six samples greater than 0.985.
It was concluded that the Astrup method for the determination of the acid-base status of the blood of horses is valid.
Indirect measurement of mean blood pressure in the normotensive and hypotensive horse. Indirect mean arterial pressure was obtained from the tails of 78 anaesthetised and unanaesthetised normotensive and hypotensive horses. Data were obtained to determine the optimum cuff width in relation to tail circumference. A cuff that is too wide under-estimates and a cuff that is too narrow over-estimates blood pressure. With the optimum cuff width, which is slightly in excess of about one-fifth of the tail circumference, indirect mean blood pressure was obtained consistently in normotensive and hypotensive animals with mean blood pressures of 40 mmHg and frequently in animals with pressu...
The presence of precipitating antibodies in the sera of horses with chronic obstructive pulmonary disease (COPD). The sera of horses affected and not affected with chronic obstructive pulmonary disease (COPD) were examined for precipitins to Micropolyspora faeni and Aspergillus fumigatus. Precipitins to both antigens were not restricted to COPD cases but occurred more frequently in animals affected with COPD. Many animals without detectable precipitins responded clinically to inhalation challenge with these antigens.
Sound spectography in the diagnosis of equine respiratory disorders: a preliminary report. One problem in the diagnosis of subclinical roarers is that abnormal auditory signals occur only during a fast gait, and these fade quickly. This paper offers a novel technique to assist this problem. Sound recordings were obtained from five horses following exercise; two roarers, two non-roarers, and one suspected roarer. These signals were converted into spectrograms by Rayspan processing. All frequencies in the 0 to 2.25 kHz range during both inspiration and expiration, as well as occasional noises in the 2–4 kHz band, characterised roarers. Signals from non-roarers consisted of frequenci...
Granular cell tumour (myoblastoma) in the lung of a horse. A granular cell tumour (myoblastoma) occurred in the lung of an aged mare. Multiple greyish-white neoplastic nodules of various sizes almost replaced one lung. Histologically, the neoplasm consisted of small clumps of granular cells in a stroma composed of thick bands of collagen and numerous capillaries. The globoid or stellate neoplastic cells were characterized by a large number of eosinophilic, PAS-positive, diastase-resistant cytoplasmic granules. Ultrastructurally, the granules were of two types: (a) homogeneous, electron-dense granules and (b) multimorphous granules that resembled cell ...
The Fourth Sir Frederick Hobday Memorial Lecture. Back problems in the horse–a look at past, present and future progress. The horse is predisposed to back injury by virtue of the type of work and intensity of competition
to which it is subjected nowadays. This paper reviews some of the inherent difficulties in establishing meaningful criteria for the diagnosis and treatment of these injuries. It highlights some
of the large gaps in knowledge, particularly in relation to the causative factors involved and the
biomechanics of the equine spine. One controversial area in diagnosis and treatment concerns
the possible subluxation of vertebral dorsal spinous processes and their subsequent reposition by
means of man...
[Prevalence of Dictyocaulus arnfieldi (Cobbald, 1884) Railiet & Henry 1907, in Pantaneira breed horses of the region of Pocone, MT]. The authors sacrificed fifty-five horses originated from the "Pantanal", lowlands in the State of Mato Grosso in two different periods, droughty period and flooded and they described for the first time the Dictyocaulus arnfieldi in Mato Grosso. Relationship between droughty and flooded periods proved not to occur.
Probstmayria vivipara pinworms in ponies. From 1967--1978 observations were made on the presence of the small equine pinworm, Probstmayria vivipara, in seven experimental ponies. The life cycle of this nematode is unusual in that it is endogenous with development of all stages occurring within the host's digestive tract. Initially, worms were found in the feces of four of seven ponies following treatment with thiabendazole but the infection was later transmitted to all ponies possibly via coprophagy. Still later, based on fecal and postmortem examinations, four of the seven ponies lost their pinworm burdens. At necropsy, the principal...
A preliminary report on the use of warfarin in the treatment of navicular disease. Twenty horses suffering from navicular disease were treated with warfarin given orally. The dosage was to effect, to give a 2 to 4 second prolongation of the one stage prothrombin time (OSPT). Dosage was initially at a rate of 0.018 mg/kg, changing the dose by amounts of 20 per cent until the required dose was achieved. Final dose rates varied from 0.012 mg/kg to 0.75 mg/kg. All the cases treated received warfarin daily throughout the trial. Seventeen of the animals became sound and the remaining 3 showed a marked improvement in their gait. The mean of the ages of the horses was 7.5 years, the...
