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.
Aspects of genetics and disease in the horse. Dead or deformed foals produced by purebred parents represent an economic and emotional loss to the horse breeder. To avoid repeating production of such defective foals, the breeder may seek assistance in identifying the possible environmental or genetic causes for such animals. Only a few genetic diseases of the horse have been rigorously defined. Selected rare genetic diseases that prevent reproduction, cause the natural death or necessitate the humane destruction of a foal before it fulfills its intended purpose serve as examples for the definition of genetics of other deleterious diseases ...
Pancreatic beta-cell function in the fetal foal and mare. Insulin secretion and the factors influencing beta-cell function were investigated in the chronically catheterized fetal foal and mare during the second half of gestation. The response of the fetal beta cells to exogenous glucose was also examined. The mean concentration of insulin in the fetal foal was 7.5 +/- 0.5 (S.E.M.) microunit./ml (n = 20) which was significantly less than the corresponding maternal value of 49.0 +/- 5.0 microunit./ml (n = 20, P < 0.01). The insulin concentration in non-pregnant horses was 24.5 +/- 1.5 microunit./ml (n = 5) which was significantly less than the value...
Attempted induction of an avian eosinophilia using various agents. A series of experiments is described in which attempts were made to produce an avian eosinophilia using various agents. Although none of the experiments was decisive, two demonstrated a slight rise in the eosinophil counts. In one experiment horse serum was injected into a group of fowls on alternate days for 42 days. No eosinophils were seen in any blood smears after this treatment. After a rest period of eight days the birds received further injections for 10 days. The mean eosinophil count rose to over 4 per cent with a range of 1 to 11 per cent. It is considered that this type of response ...
Effect of pyrrolizidine alkaloid-induced hepatic disease on plasma amino acid patterns in the horse. Plasma amino acid patterns were studied in 6 clinically normal adult horses during the course of hepatic disease induced by feeding them plants containing pyrrolizidine alkaloids. At death, there were significant (P less than 0.01) increases in glutamine, proline, tyrosine, asparagine, lysine, histidine, alanine, phenylalanine, methionine, aspartic acid, and ornithine values. There were no significant changes in glycine, valine, isoleucine tryptophan, and arginine values. There were significant (P less than 0.01) decreases in citrulline. Ammonia increased 4-fold. Alpha-Aminoadipic acid and alp...
The effect of season on the ovulatory response of Merino ewes to serum from pregnant mares. Groups of 50 ewes were injected with serum from pregnant mares on 5 occasions, 3 months apart, and ovulation rate was estimated at laparoscopy. In Exp. 1, new ewes were used at each time and 3 dose rates (identical to 400, 630 and 1000 i.u. PMSG) were studied. In Exp. 2, the same ewes were used throughout and only 1 dose was given (1000 i.u.). In both experiments the response in ovulation rate of ewes varied significantly throughout the year, with the lowest response in spring (September) and the highest in autumn (March). The ewes in Exp. 2 were as responsive at the end as at the beginning of...
Hydatidosis in donkeys in Morocco. The lungs and livers of 429 adult donkeys from different parts of Morocco were examined for hydatid cysts; 4·2% of lungs were infected and 2·1% of livers. Most of the cysts were small and had very hard thick walls; 61% of the donkeys had only one hydatid cyst; 78·5% of them were sterile and 29% caseated or calcified.
[Results obtained with Dermazellon in the treatment of wounds in horses (author’s transl)]. In view of the beneficial effect of Dermazellon on the healing of wounds healing poorly, reported in human patients, a number of wounds caused by wire in horses were treated with Dermazellon. Dermazellon gel was readily applicable and produced satisfactory results.
Histochemical properties of muscle fibres types and enzyme activities in skeletal muscles of Standardbred trotters of different ages. Fibre characteristics and enzyme activities were determined for the gluteus, semitendinosus, vastus lateralis and triceps brachii muscles of 55 Standardbred trotters of different ages. Four fibre types (I, IIA, IIB, IIC) were demonstrated by histochemical staining of myofibrillar adenosine triphosphatase after preincubation at different pH values. Type II fibres predominated in all the muscles and the type IIA/IIB ratio was higher in horses over 5 years than in younger horses, except in the vastus in which the IIA/IIB ratio did not change with age. The vastus had the highest proportion of type...
Assessment of wall shear stress in arteries, applied to the coronary circulation. Time dependent wall shear rates cannot be directly or accurately measured in arteries using presently available techniques. Here a simple method is presented for calculating them from a single measured velocity waveform (either centreline or cross-sectionally averaged velocity). The method involves only Fourier analysis and the application of given formulae, and it is expected to be approximately valid in any segment of artery which has no branches or sharp curves for a distance of several diameters. It is shown, however, that a frequency response of 30 Hz is required in the velocity measuring...
Echocardiography in assessing mitral valve motion in 3 horses with atrial fibrillation. Echocardiography is a non-invasive, safe means of assessing intracardiac structures and their motion. In the normal motion of the mitral valve there is anterior motion noted during atrial systole. In 3 horses with atrial fibrillation the mitral valve motion had no anterior motion to correspond with atrial contractions. Quinidine returned the electrocardiogram of one horse to a sinus rhythm after which echocardiography demonstrated the reappearance of the anterior motion of the mitral valve.
Absorption, excretion and tissue distribution of stable zinc and 65zinc in ponies. Absorption excretion and tissue distribution of stable Zn and 65Zn in mature ponies were studied in three experiments. In the first experiment, the metabolism of stable, dietary Zn and intravenously administered 65Zn was studied in three ponies in a 3 X 3 Latin square design. The ponies were fed a corn and beet pulp diet containing 35 mg Zn/kg or the same diet with 250 or 520 mg of supplemental Zn as ZnO. The ponies absorbed and retained more stable Zn when fed 250 mg of supplemental Zn that when fed the basal diet alone or the basal diet plus 520 mg of supplemental Zn. The ponies retained mor...
Isolation of Yersinia enterocolitica from selected animal species. Yersinia enterocolitica was isolated from 5 of 1,002 fecal samples taken from laboratory rats and mice, hamsters, dogs, cats, pigs, cattle, horses, and deer. Two isolates were from dogs (2 of 202; 1%) and 1 from a pig (1 of 107; 0.9%). The 3 isolates were biotype 1. Atypical environmental Y enterocolitica was isolated from a cow (1 of 141; 0.7%) and a horse (1 of 101; 1%). Isolates were not recovered from the other animal species.
Lactic acidosis and arterial hypoxemia during sublethal endotoxemia in conscious ponies. Effects of a sublethal IV dose (10 micrograms/kg of body weight) of Escherichia coli endotoxin were studied in 7 conscious ponies. Arterial blood gases and plasma lactic acid were determined periodically throughout the 180 minutes of the study. Arterial hypoxemia occurred within 5 minutes despite intense hyperventilation. Colic and diarrhea occurred in all ponies within 30 minutes after endotoxin administration. Metabolic acidosis developed within 30 minutes and persisted throughout the study, indicating widespread reduced tissue perfusion.
Dust levels in a riding stable. Over a period of 4 months, in winter, the mean concentration of airborne particles in the ambient air of a riding stable was 0.41 mg/m3. This value was significantly higher than that found outdoors (0.04 mg/m3). During the day, levels of airborne particles were highest when stalls were cleaned and soiled bedding from the previous night replenished, and lowest when all stable activities had ceased. Fine particles, capable of entering the pulmonary alveoli, constituted 30 to 40 per cent of the total mass concentration of airborne particles.
Influence of head height on arterial blood pressure in standing horses. Eighteen horses were used to investigate the influence of head position on arterial blood pressure, measured indirectly at the coccygeal artery. Head height significantly altered systolic pressure, diastolic pressure, pulse pressure, and mean arterial pressure, such that head-lowering decreased and head-raising increased all variables.
