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.
Effect of a tart cherry juice blend on exercise-induced muscle damage in horses. To evaluate whether administering a tart cherry juice blend (TCJB) prior to exercise would reduce skeletal and cardiac muscle damage by decreasing the inflammatory and oxidative stress response to exercise in horses. Methods: 6 horses. Methods: Horses were randomly allocated into 2 groups in a crossover study with a 2-week washout period and orally administered either TCJB or a placebo solution (1.42 L, twice daily) in a double-masked protocol for 2 weeks prior to a stepwise incremental exercise protocol. Horses were tested for serum activities of creatine kinase and aspartate aminotransferase...
Role of the hypoglossal nerve in equine nasopharyngeal stability. The equine upper airway is highly adapted to provide the extremely high oxygen demand associated with strenuous aerobic exercise in this species. The tongue musculature, innervated by the hypoglossal nerve, plays an important role in airway stability in humans who also have a highly adapted upper airway to allow speech. The role of the hypoglossal nerve in stabilizing the equine upper airway has not been established. Isolated tongues from eight mature horses were dissected to determine the distal anatomy and branching of the equine hypoglossal nerve. Using this information, a peripheral nerve ...
Overtrained horses alter their resting pulsatile growth hormone secretion. The influence of intensified and reduced training on nocturnal growth hormone (GH) secretion and elimination dynamics was studied in young (1.5 yr) Standardbred geldings to detect potential markers indicative for early overtraining. Ten horses trained on a treadmill for 32 wk in age-, breed-, and gender-matched fixed pairs. Training was divided into four phases (4, 18, 6, and 4 wk, respectively): 1) habituation to high-speed treadmill trotting, 2) normal training, in which speed and duration of training sessions were gradually increased, 3) in this phase, the horses were divided into 2 groups:...
Incidence of animal poisoning cases in the Czech Republic: current situation. This article reports the most frequent cases of poisoning in farm animals, horses, cats, dogs, wild animals, fish and honey-bees in the Czech Republic. At present, there are fewer cases of acute poisoning caused by high doses of toxic substances but there are more and more cases of chronic poisoning as a consequence of environmental pollution.
Dimensions of diastemata and associated periodontal food pockets in donkey cheek teeth. Equine cheek teeth (CT) diastemata often cause deep periodontal food pocketing and are therefore regarded as a painful dental disorder of equidae. However there appears to be no information available on the size or shape of these diastemata. This post mortem study examined 16 donkey skulls (mean age = 32-years) containing 45 CT diastemata to define the anatomical shape and dimensions of these diastemata, and of the associated periodontal food pockets that occur with this disorder. Diastemata were found to more commonly involve mandibular (56.0%) compared with maxillary CT (44.0%), and 71.0% of...
Mechanical recovery of inhibited cyathostomin larvae from equine intestinal tissue. The Stomacher is very widely used in food and medical research for extracting tissues. To determine whether nematode larvae were disrupted by the Stomacher, L3 larvae of Haemonchus contortus were homogenised for up to 40 min at full power but no larval disruption occurred. Therefore, tissue from the mucosa and submucosa of the caecum of horses collected from a licenced abattoir was treated to determine whether inhibited cyathostomin larvae could be extracted. The optimum time on full power for a 10-g sample was 20 min, and in three out of five caecal samples from different horses, significantl...
Horizontal moment around the hoof’s centre of pressure during walking in a straight line. Joint congruity and ligaments restrain the distal limb joints from excessive motion in the transverse and frontal planes, but the magnitudes and direction of the horizontal twisting moments around the hoof's centre of pressure (CoP) that induce these motions are unknown. Objective: To quantify the horizontal moment around the vertical axis through the hoof's CoP at walk, and to determine whether these are symmetric. Methods: Nine sound Thoroughbred horses (mean age 53 years; mean mass 502 kg) were led at walk in a straight line across a Kistler force platform. Five trials were collected for ea...
Thirty-two component finite element models of a horse and donkey digit. The finite element (FE) method is the most powerful modelling technique available to explicate the biomechanics of the digit. It has already proved to be of high value in human podiatry. However, accurate models of the complex anatomy of the horse and donkey digit are currently lacking. Objective: To develop FE models of the horse and donkey digit from computed tomography data, including all functionally relevant anatomy, and to perform simulations to replicate prestrain in the flexor tendons and quasistatic weightbearing. Methods: Computed tomography data of the front right digits were obtain...
Efficacy of moxidectin against cyathostomins after long-term use in a large herd of draught horses with a high stocking density. This study was undertaken to determine whether resistance to moxidectin had developed in a large herd of draught horses, maintained on a small acreage, which had been routinely treated with moxidectin for five years. Faeces were collected for egg counts immediately before moxidectin gel was administered orally, and seven, 30, 60 and 90 days later. The faecal egg counts were significantly reduced at seven and 30 days after treatment, but were not significantly different from pretreatment counts at 60 and 90 days after treatment. There was no evidence of resistance having developed.
Significant injuries in Australian veterinarians and use of safety precautions. A high injury prevalence has been reported among veterinarians. Studies describing the factors associated with injury have been limited. Objective: To describe the characteristics of serious injuries and the use of safety precautions at the time of injury in Australian veterinarians. Methods: Graduates in veterinary medicine from Australian universities completed questionnaires asking about injuries during their professional career including type of injury and circumstances during which injury occurred. Results: A total of 2188 significant injuries were reported. Injuries were most frequently ...
The role of land use patterns in limiting the spread of equine influenza in Queensland during the 2007 epidemic. In 2007, an epizootic of equine influenza (EI) occurred in Australia, involving parts of the states of Queensland and New South Wales. Following an extensive control program, the disease was eradicated within 4 months, after infecting more than 75,000 horses on over 10,000 properties. In Queensland, examination of land use patterns revealed that the majority of infected premises (89.5%) were located in one of three land use classes viz. rural residential, residential-unspecified or grazing natural vegetation. All nine clusters of infection in Queensland were surrounded to some degree by parcel...
A single-nucleotide polymorphism in a herpesvirus DNA polymerase is sufficient to cause lethal neurological disease. Epidemiological studies have shown that a single-nucleotide polymorphism in the equid herpesvirus type 1 DNA polymerase gene is associated with outbreaks of highly lethal neurological disease in horses. Reverse genetics experiments further demonstrated that a G(2254) A(2254) nucleotide mutation introduced in neurovirulent strain Ab4, which resulted in an asparagine for aspartic acid substitution (D(752) N(752)), rendered the virus nonneurovirulent in the equine. Here, we report that the nonneurovirulent strain equid herpesvirus type 1 strain NY03 caused lethal neurological disease in horses af...
A biological hazard of our age: bracken fern [Pteridium aquilinum (L.) Kuhn]–a review. Bracken fern (Pteridium aquilinum) is the fifth most distributed common weed species of the world. Its ecological distribution is very wide, and the plant can grow and spread successfully on many types of soil. The cover of P. aquilinum is--in some cases--remarkable (e.g., in the United Kingdom). Bracken fern contains different poisonous agents: some cyanogen glycosides, factors (agents) of antithiamine character (thermolabile thiaminase and thermostable other compounds) and factors of carcinogenic activity (first of all ptaquiloside). This paper summarises and reviews different toxicological ...
Assessment of the anti-Naja haje antibodies elicited in a low dose multi-site immunization protocol. The horse antibodies to Naja haje (Nh) elicited in a low dose multi-site immunization protocol were investigated from binding perspective in the context of antivenom maturation. We found that, this protocol evoked the production of lethality neutralizing avid antibodies in the first round of immunization which increases over the successive immunization rounds. The changes and the relative changes in the antibody parameters of each horse were taken as a measure for the efficacy of its immune system to respond by gaining and magnifying the antivenom parameters. While the avidity increases over t...
Randomised controlled trial of the treatment of pastern dermatitis with a formulation containing kunzea oil. The efficacy of an ointment containing kunzea oil for the treatment of horses with localised acute or chronic pastern dermatitis was assessed. Thirty-seven horses were randomly allocated to treatment with an ointment containing either 20 per cent kunzea oil (test) or 2 per cent ketoconazole (control). Only 21 of the horses completed the study. The severity of the lesions was assessed before and after seven days of treatment. The kunzea oil formulation resulted in a significant decrease in the median total area of the lesions from 40 cm(2) (range 3 to 252 cm(2)) to 0 cm(2) (range 0 to 34 cm(2))...
Combining microsatellite and pedigree data to estimate relationships among Skyros ponies. Relationship coefficients are particularly useful to improve genetic management of endangered populations. These coefficients are traditionally based on pedigree data, but in case of incomplete or inexistent pedigrees they are replaced by coefficients calculated from molecular data. The main objective of this study was to develop a new method to estimate relationship coefficients by combining molecular with pedigree data, which is useful for specific situations where neither pedigree nor molecular data are complete. The developed method was applied to contribute to the conservation of the Skyr...
Localized, plexiform, diffuse, and other variants of neurofibroma in 12 dogs, 2 horses, and a chicken. In humans, neurofibroma and schwannoma are distinct entities within the group of benign peripheral nerve sheath tumors. In the veterinary literature, these tumors are often classified together simply as benign peripheral nerve sheath tumors, and diagnostic criteria for their subclassification are not well established. We describe peripheral nerve sheath tumors with microscopic, immunohistologic, and ultrastructural features similar to those in subtypes of human neurofibroma in 12 dogs, 2 horses, and 1 chicken. Dogs were of different breeds and were aged 2 months to 15 years. The canine tumors ...
alpha-Lipoic acid supplementation enhances heat shock protein production and decreases post exercise lactic acid concentrations in exercised standardbred trotters. Heat shock protein (HSP) expression is an adaptive mechanism against the disruption of cell homeostasis during exercise. Several antioxidant supplementation strategies have been used to enhance tissue protection. In this study, we examined the effects of a redox modulator, alpha-lipoic acid (LA) on HSP responses in six standardbred trotters following intense aerobic exercise. DL-LA supplementation (25 mg kg(-1) d(-1)) for five weeks increased the resting levels of HSP90 (1.02+/-0.155 in control and 1.26+/-0.090 after supplementation in arbitrary units) and the recovery levels of inducible HSP7...
Chronology and sequence of emergence of permanent premolar teeth in the horse: study of deciduous premolar ‘cap’ removal in Thoroughbred racehorses. There are few published data to support the ages of emergence of permanent dentition widely reported in horses. Objective: To clarify the chronology and sequence of permanent premolar (PM) tooth emergence in Thoroughbred racehorses. Methods: A prospective study was undertaken in which records were kept of deciduous PM 'cap' extractions performed during routine dental examinations in Thoroughbred racehorses. Mixed effects multiple regression analysis was used to relate the observed ages, measured in days, for PM 'cap' extractions simultaneously with different predictive variables. Care was take...
Relationships between early foal health, future performance and their dams reproductive health. The objectives of this study were to investigate: (i) relationships between early foal health and their dams' reproductive health at mating/conception as well as after parturition and (ii) health status during early foal life and its association with performance as an adult. The study included 35 foals showing clinical symptoms indicating septicaemia, sometimes in combination with other disturbances, within their first 18 h postpartum (Group I). Eighty-eight foals that were healthy during their first few days of life were used as control (Group II). All foals were born in the same region of Sw...
