the aim of this study was to determine the prevalence and type of ophthalmic diseases among horse populations in the suburbian riding clubs of tehran. ophthalmologic examinations were performed in 901 horses and ocular lesions were diagnosed in 40 (4.4%) animals. in the 54 eyes of these horses that had ocular defects, 103 ocular abnormalities were detected. of those horses affected, 65% showed ...

BACKGROUND A hyperbolic relationship between β-cell response and insulin sensitivity (IS) has been described in several species including rodents, dogs, and humans. This relationship has not been elucidated in the horse. HYPOTHESIS/OBJECTIVES To determine whether the hyperbolic relationship between β-cell response and IS exists in horses by using indices of β-cell response from the oral sugar...

This study aimed to evaluate the effects of a supplement that contains resveratrol and hyaluronic acid (RH supplement) in aged lame horses. A total of 16 horses of both sexes, aged between 15 and 22 years, weighing between 350-450 kg and showing lameness due to arthritis of the knee, hock, stifle, and fetlock joints and stiffness owing to ageing were used for the study. They comprised eight hor...

Nine trailer loads of horses (n = 306) transported to slaughter facilities with distances ranging 596 to 2,496 km were studied to characterize the type of horses used in commercial markets and the physiological responses and number of injuries due to transportation under summer environmental conditions. Slaughter horse candidates were middle-aged (11.4+/-.4 yr), possessed moderately fleshy body...

Since the dawn of civilization, human beings have sought ways to identify the animals they own in order to differentiate them from animals owned by others. In the United States, early equine identification consisted of a word description or graphic sketch of the animal. Hot iron branding, introduced by Spanish settlers in the early 1800s, was adopted chiefly by ranchers in the western states. L...

Horse breeding in South Africa started in 1652, shortly after the 1st European settlement in the Cape. African horsesickness posed a serious problem and after a devastating outbreak of the disease in 1719, horses were largely replaced by oxen for agricultural and transport purposes but remained important from a sporting and military point of view. Examples of the latter are the export of horses...

Horses can acquire cheek teeth (CT) fractures through many mechanisms, including external trauma, e.g. as a result of kicks, biting inanimate objects and crib biting. These traumatic fractures mainly occur in the anatomically more susceptible rostral mandibular CT. Fractures to CT can also be caused by iatrogenic trauma during dental treatments, such as cutting tall CT overgrowths with dental “...

Obligate anaerobes are important etiological agents in pneumonia or pleuropneumonia in horses, because they are isolated more commonly from ill horses that have died or been euthanized than from those that survive. We performed bacterial identification and antimicrobial susceptibility testing for obligate anaerobes to establish effective antimicrobial therapy. We used 16S rRNA gene sequencing t...

background: neospora caninum , an obligate intracellular protozoan parasite, is recognized as a major cause of abortion in cattle, while limited information is presently available on the seropreva­lence of neospora antibodies in horses' worldwide .the aim of the present study was to de­termine serologic prevalence of neospora infection in horses in iran. methods: sera from 150 horses from mashh...

Cardiac arrhythmias, caused by disorders in the generation and transmission of cardiac impulses, is included among the heart disorders that cause inefficient blood circulation. The most commonly-used method for diagnosing this disorder is electrocardiography. In this study, we aimed to identify and diagnose different types of arrhythmia prevalent among the seemingly-healthy horses of Sanandaj C...
