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.
Retropulsion-propulsion in equine large colon. The circular and longitudinal muscle coats of equine "midcolon" were found to be directly electrically coupled. They appear to act in concert, in healthy animals, as a pacemaker in the area of the large colon pelvic flexure, for retropulsive-propulsive myoelectrical events. The retropulsive events keep the cecum and right ventral and left ventral divisions of the colon filled, imposing a delay time for fermentation of cellulose and for bacterial protein synthesis. Point-to-point involvement of adjacent colon sections was slowed by cooling the intestinal contents with no adverse clinical signs....
Serum and intracellular retinol in the equine. 1. Serum and intracellular distribution of retinol was determined in equines maintained on four levels of vitamin A intake. 2. The form of retinol transported in serum was determined by gel filtration and chromatography to be a complex of retinol bound to a protein of molecular weight (MW) of approximately 20000, which was in turn complexed probably with prealbumin to yield a complex with a MW of 75000 to 80000. 3. Increasing dietary vitamin A levels enhanced the concentration of lipoprotein-bound retinyl esters in the plasma. 4. Vitamin A in the liver cytosol was found predominantly as retiny...
Recovery of microorganisms from synovial and pleural fluids of animals using hyperosmolar media. L-phase (CWD) broth and plate media were used in parallel with conventional microbiological media during a 3-year period for culturing synovial and pleural fluids of animals. Two kinds of recoveries were obtained where parallel conventional methods were negative: (1) parent or normal bacteria, in very low numbers; and (2) Type B CWD variants in equally low numbers. Organisms in group 1 were: Streptococcus zooepidemicus from horses (2x); beta-hemolytic streptococci, Lancefield Gp. G (2x); Staphylococcus aureus; Actinobacillus, and Actinomyces viscosus. Group 2 consisted of Bacteroides sp., Prop...
[ECG similarities in the parents and offspring of thoroughbred horses]. The ECG characters were studied in two sires (Manrico and Infernal) and their 26-membered set of progeny as well as in one mare (Victoire) and her five daughters. The confer of some ECG characters from the sire's side as well as from the mare's side to the offspring was demonstrated. The consistency of some ECG characters was particularly obvious in externally dominant Manrico sire and his offspring as well as in the breeding mare and her five daughters (inclination of the electric cardiac axis, intrinsicoid deflexion lag, P wave shape, deep S in the 3rd connection).
Acid-base and electrolyte alterations in horses with exertional rhabdomyolysis. In examination of the acid-base and electrolyte status of 7 horses with acute exertional rhabdomyolysis, the most consistent abnormality was hypochloremia. Metabolic acidosis was not evident in any of the horses. Therefore, the use of sodium bicarbonate in treatment of such disorders may not be indicated in all cases.
Effect of diethylcarbamazine on Strongylus vulgaris infection in ponies. Shetland ponies (n = 4) were given diethylcarbamazine orally at a dose level of 22 mg/kg/day for 1 week before they were inoculated with 800 third-stage larvae of Strongylus vulgaris. Treatment was continued for 86 (1 pony) or 200 days (3 ponies) after the inoculation. As compared with the changes seen in a similarly inoculated group of ponies (group 2) which were not treated, diethylcarbamazine did not prevent the clinical or pathologic changes due to the migrating larvae. Fewer adult parasites were recovered at necropsy from treated ponies than from nontreated (group 2) ponies, even when tre...
Systemic d-phenylalanine and d-leucine for effective treatment of pain in the horse. This study showed that subcutaneous injection of a solution of D-amino acids produced effective analgesia in horses. It is postulated that systemic D-phenylalanine and D-leucine may become one of the safe, effective and nonaddictive drugs for acute and chronic pain treatment. These D-amino acids cause analgesia by presumably preserving brain endorphins. They may bind reversibly to enkephalinases and prevent enzymatic degradation of enkephalins.
Leukotriene generation by eosinophils. Horse eosinophils purified to greater than 98% generated slow reacting substance (SRS) when incubated with the calcium ionophore A23187. On a per cell basis, eosinophils generated four to five times the SRS produced by similarly treated horse neutrophils. Eosinophil SRS production was inhibited by 5,8,11,14-eicosatetraynoic acid and augmented by indomethacin and arachidonic acid, suggesting that it was a product(s) of the lipoxygenase pathway of arachidonic acid metabolism. Compounds with SRS activity were purified by high-pressure liquid chromatography (HPLC) and identified by ultraviolet spe...
Myocardial necrosis secondary to neural lesions in domestic animals. Focal myocardial necrosis secondary to neural lesions was diagnosed in 2 dogs and 1 horse. In each case, the neural lesions were traumatic in origin. Spinal cord injury was evident in 1 dog; brain damage was evident in the other dog and presumably in the horse. Retrospective analysis of necropsy material showed that many species were affected, without apparent age or sex predisposition. Central nervous system injury resulting from trauma, infection or space-occupying lesions was associated with acute myocardial necrosis in all cases. The myocardial necrosis was rarely fatal; however, it did ca...
Effect of number and frequency of inseminations on fertility of mares. Data from 257 normally cyclic mares used in trials over a 10-year period were examined to establish the relationship between the number of inseminations per cycle, duration of oestrus and pregnancy rate. Mares that became pregnant were inseminated more (P less than 0.05) frequently per cycle than mares that did not become pregnant (3.4 versus 2.8). First-cycle pregnancy rates of 22.2, 34.0, 38.6, 52.5, 58.3 and 52.2% were attained when mares were inseminated 1, 2, 3, 4, 5 or 6 or more times per cycle, respectively. The duration of oestrus in mares that became pregnancy was longer (P less than ...
A comparison of agents for inducing parturition in mares in the pre-viable and premature periods of gestation. Various regimens of prostaglandins, alone or followed by oxytocin, were given to induce parturition in mares during the pre-viable and premature periods of gestation and in near-term mares. The most successful method of induction was found to be 2 i.m. injections of 500 micrograms fluprostenol (Equimate: I.C.I.) at a 2-h interval followed (if necessary) by 10-20 i.u. oxytocin injected i.v. in 5 i.u. serial increments every 15-20 min. Peak concentrations of the prostaglandin metabolite (PGFM) in response to the inducing agents were shown to be associated with delivery at, but not before, 320 da...
Antibodies to the zona pellucida in mares. Cross-reactivity tests indicated that the equine zona pellucida shares common antigen(s) with porcine zona. Porcine oocytes were therefore used to test for the presence of zona antibodies in the sera of horses. Serum samples were collected from 65 mares infertile for unexplained causes: 7 mares were strongly positive for antibodies reactive to porcine zona pellucida as determined by an indirect immunofluorescence method. Of these 7 mares, aged 8-23 years, 2 were nulliparous and 5 were multiparous. Zona-covered horse oocytes were treated with sera from 4 mares previously identified as zona posi...
The cryo-jaw, a clamp designed for in vitro rheology studies of horse digital flexor tendons. A clamp designed for holding tendons in force/elongation studies is described. No slippage occurred when tensile forces up to 13,800 N were applied to horses digital flexor tendons fixed in this clamp.
Tendon fibromas in 2 horses. FIBROMAS arise from connective tissue and occur in all domestic animals (Smith, Jones and Hunt 1972; Stannard and Pulley 1978). They are most frequently noted in the dermis or subcutis, but may be present wherever connective tissue occurs. In the dermis and subcutis of the horse fibromas are grossly similar to sarcoids and may be difficult to differentiate (Baker and Leyland 1975). Fibromas have been described as tumours of the tendon sheath or tendon proper in man (Flynn 1975), but have not been described in this location in the horse.
