Topic:Equine Health
Equine health encompasses the study and management of diseases, disorders, and overall well-being of horses. It involves understanding various physiological systems, preventive care, and treatment strategies to maintain optimal health in equine populations. Common areas of focus include nutrition, infectious diseases, orthopedic conditions, and reproductive health. Research in equine health aims to advance knowledge on diagnostic methods, therapeutic interventions, and management practices that improve horse welfare and performance. This page collects peer-reviewed research studies and scholarly articles that explore the diverse aspects of equine health, offering insights into current findings and advancements in the field.
Arteria intercarotica caudalis and its homologue in the domestic animals. The arteria intercarotica caudalis was observed to be present in the dog, horse and cat but was reticulated in the case of cattle, sheep, goat, and pig. The latter structure was a homologue of the former and represented an important intercarotid communication present in most of vertebrate.
Thermography in veterinary medicine. Thermography in veterinary medicine has hitherto been proven to be a method of great value in the detection of orthopaedic lesions in racehorses. Lesions of the musculo-skeletal system affecting tendons, joints, bones and skeletal muscle can be demonstrated and documented at an early stage thereby preventing the development of more serious lesions.
Epidemic Venezuelan equine encephalitis in North America in 1971: vertebrate field studies. Epidemic Venezuelan equine encephalitis in North America in 1971: vertebrate field studies. Am J Epidemiol 101:36-50, 1975.-In June 1971, epidemic Venezuelan equine encephalitis (VEE) invaded the lower Rio Grande Valley in south Texas. The Boca Chica area of Cameron County was selected as a study site to investigate vertebrate involvement in the natural cycle of epidemic VEE on the basis of considerable evidence of VEE virus activity there in equines, humans, and mosquito vectors. Only one VEE virus isolation was made from 4739 wild and domestic non-equine vertebrates, although numerous equine...
Double diffusion in gel tests with Paul-Bunnell antibodies of infectious mononucleosis sera. Double diffusion tests in gel were employed for studies of reactions between infectious mononucleosis sera and extracts of bovine, sheep and equine erythrocyte stromata. The extracts were obtained by ultrasonication of stromata prepared from trypsin-digested erythrocytes. The reaction with bovine stroma extract was composed, in many instances, of two lines. A single line was observed in reactions with sheep and equine stroma extracts. This line merged into a reaction of partial or complete identy with one of the lines formed with bovine stroma extract. Evidence was obtained that some infectioo...
Cobalt metabolism in horse. Serum level and biosynthesis of vitamin B12. The levels of serum vitamin B were determined on 16 mature partly warm-blooded, partly Finnish rural-race horses by the radioisotopic competitive inhibition assay method. The mean value from three samplings carried out in dupli- or triplicate was 1.54 ± 0.16 ng/ml. The utilization of serum inorganic cobalt for cyanocobalamin synthesis was studied on two geldings, which received a dose of 200 µCi CoGl i.v. A Sephadex G-100 gel filtration was carried out with the serum proteins from serial blood samplings at different time intervals 15 min. to 48 hrs. after administration. The gel filtration s...
Cardiac output in the conscious and anaesthetised horse. Cardiac output in the horse was measured before and at predetermined times during 2-hour periods of thiopentone-halothane and thiopentone-diethyl ether anaesthesia. Left ventricular stroke volume was decreased to a similar extent during anaesthesia with each volatile agent, but a greater reduction in cardiac output occurred during halothane anaesthesia. This finding reflected the differing effects of halothane and ether on heart rate, a slight bradycardia occurring with the former agent while ether produced a small degree of tachycardia. The latter effect was attributed to enhanced sympathoadr...
Studies on the dynamics of Strongyloides egg release under stud conditions. The eggs of Strongyloides westeri were found in the faeces of the foals from the 16th day of their life, with a peak in their numbers between the 30th and 40th day of life. Egg release ceased in all foals irrespective of their date of birth in the months July-August. Parallel examinations of the mares were negative. Recommendations for the control of strongyloidosis in foals are given.
[Contribution to the antigenic study of influenza viruses in animals. II.–Antibodies, antineuraminidase in horse: conditions of apparition and importance (author’s transl)]. In the first part of this paper the conditions for a specific titration of antibodies against the neuraminidase (N) of each of the two horse virus subtypes are defined. The antigens used are: the H72Neq 1 recombining agent to measure the anti Neq1 antibodies and the A/Duck/Ukraine/63 strain for the anti Neq2 antibodies. The immunity response to neuraminidase appears after the natural disease; this response is studied in two foci, one due to a virus belonging to the A equi I subtype (Loire 73 strain), the other to a virus of the A equi 2 subtype (SHN 73 strain). The kinetics of apparition of an...
Abnormal flexion of the corono-pedal joint or “contracted tendons” in unweaned foals. A condition frequently misnamed "contracted tendons" is described in unweaned foals. Various theories regarding its aetiology are examined. Overfeeding and lack of exercise are suggested as being the most likely causes, leading to excessive growth of the long bones. An effective method of treatment is described. "Contracted tendons" in yearlings are also discussed.
The growth of African horse-sickness virus in embryonated hen eggs and the transmission of virus by Culicoides variipennis Coquillett (Diptera, Ceratopogonidae). Seven-day-old embryonated hen eggs were infected with African Horse Sickness virus by the yolk sac and intravenous routes. Virus reached a high titre in the blood of infected embryos. Culicoides variipennis midges which took a blood meal from infected eggs became infected with virus, and after 7 days at 26 degrees - 27 degrees C transmitted African Horse Sickness virus to uninfected eggs. C. variipennis may therefore be considered a biological vector of African Horse Sickness virus in the laboratory.
Equine anti-hapten antibody. IX. IgM anti-lactose antibodies. The immune response to a bacterial vaccine of Streptococcus faecalis (strain N) was characterized in all of the seven horses studied by the sustained production of about 90% IgM anti-lactose antibody over a period of 44 weeks with maximum values of the total antibody ranging from 4 mg/ml of serum to 12 mg/ml of serum. With respect to the binding of a lactose-containing ligand the association constants of the antibodies purified from sera obtained between 5 and 44 weeks fell in the range of 1 times 10-5 M-1 to 2 times 10-5 M-1. Not only was there no significant indication of maturation of a-fin...
Castration and other factors affecting the risk of equine laminitis. The characteristics of a series of equine laminitis cases were compared with that of other Equidae examined at the University of Missouri Veterinary Hospital and Clinic during May, 1965 through December, 1971. The model age for ponies with laminitis was 7-9 years and for all other cases the model age was 4-6 years. Also the predominant age for mares was 4-6 years and for males was 7-9 years. After controlling for age and breed differences, there were significantly fewer castrated males among the affected males than expected (P small than 0.02), indicating that hormonal factors may play a role ...
Epidemic Venezuelan equine encephalitis in North America in 1971: vector studies. A major epidemic of Venezuelan equine encephalitis occurred in south Texas in the summer of 1971. More than 1500 equines died of VEE in Texas, and 110 human cases with no deaths were reported. Vector studies in south Texas and northern Tamaulipas revealed that the overall mosquito infection rates during the peak of the epidemic were about 1:100, one of the highest rates observed for a major epidemic. Mosquito infection rates of this magnitude could easily explain the intensity of VEE outbreaks in both equines and man. A total of 943 VEE virus isolations were made from mosquitoes. Eight of the ...
