For millions of years, the stout, muscular Przewalski’s horse freely roamed the high grasslands of Central Asia. By the mid-1960s, these, the last of the wild horses, were virtually extinct: a result of hunting, habitat loss, and cross breeding with domestic horses. Recovering fromatinypopulationof12 individualsand only fourpurebredfemales, therearenownearly2,000Przewalski’s horsesaround the wo...

BACKGROUND Lower expression of secretoglobin and transferrin has been found in the bronchoalveolar lavage fluid (BALF) of a small number of horses with experimentally induced signs of recurrent airway obstruction (RAO) compared to healthy controls. HYPOTHESIS/OBJECTIVES Secretoglobin and transferrin BALF expression will be similarly decreased in horses with naturally occurring clinical signs ...

OBJECTIVE To evaluate the seasonal influence, signalment, type of hay consumed, clinical examination findings, and outcome after surgery for horses with ileal impaction. STUDY DESIGN A retrospective study. RESULTS Between 1988 and 1993, 28 horses had surgical correction of ileal impaction. There was a significantly higher rate of ileal impaction during the Fall (September-November, P = .004...

The hindgut of horses is an anaerobic fermentative chamber for a complex and dynamic microbial population, which plays a critical role in health and energy requirements. Research on the gut microbiota of Mongolian horses has not been reported until now as far as we know. Mongolian horse is a major local breed in China. We performed high-throughput sequencing of the 16S rRNA genes V4 hypervariab...

Several species demonstrate obvious motor laterality (sidedness, handedness) in their motor function. Motor laterality in the horse affects locomotion and subsequently equine performance during training and may have inherent safety implications for equitation. Some of the most commonly used identification features in the horse are hair whorls (trichoglyphs), since their specific location and ch...

scid is a lethal genetic autosomal recessive disorder that has been observed in humans, dogs, mice, and horses. affected animals are incapable of generating specific antigens for immune responses needed to protect them from infectious diseases. the frequency of affected recessive allele varies in different regions so that the outcome of normal breeding with carriers of recessive alleles is diff...

We investigated changes in heart rate (HR) and HR variability as a function of age in newborn foals to old Thoroughbred horses. Experiments were performed on a total of 83 healthy and clinically normal Thoroughbred horses. Resting HR decreased with age from birth. The relationship between age and HR fit the equation Y=48.2X-0.129(R2=0.705); the relationship between age and HR for horses 0-7 yea...

REASONS FOR PERFORMING STUDY Equine keratomycosis in the western USA has received little study, probably owing to its low prevalence. OBJECTIVES To determine clinical features, predominant fungal isolates, treatment modalities and outcomes of horses with keratomycosis in California and compare these with results from different geographic regions. METHODS Records of horses presented to the U...

OBJECTIVE To determine whether there was an association between a history of cribbing and epiploic foramen entrapment (EFE) of the small intestine in horses. DESIGN Retrospective study. ANIMALS 68 horses examined at the University of Illinois or the University of Liverpool veterinary teaching hospitals. PROCEDURE For horses examined at the University of Illinois that underwent surgery bec...

Three horses in a group of thirteen horses from one farm had acute onset of respiratory distress, fever, and anorexia. All treated with antibiotics, intravenous fluids, and oxygen with no significant improvement. Due to poor prognosis, all horses were euthanized six days after the appearance of the clinical signs and were submitted for necropsy. The characteristic lesions in all horses were mar...
