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...

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...

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...

Equine piroplasmosis is a severe disease of horses caused by the intra-erythrocyte protozoan, Theileria equi and Babesia caballi. The aim of this study was to identify equine piroplasmosis based on molecular and morphometrical features in horses in suburb of Urmia, West Azerbaijan province, Iran. From April to September 2011, a total number of 240 blood samples were collected ...

Clenbuterol is a b2-agonist bronchodilator and mucokinetic drug. When administered at the recommended dose of 0.8 mg/kg q 12 h, it reaches plasma levels that should relax airway smooth muscle. However, the measurable degree of bronchodilation achieved may not always be clinically obvious even in horses with heaves. After a ten-day treatment (0.8 mg/kg q 12 h), the half-life of elimination from ...

A nonlinear time domain seakeeping analysis has been performed for high-speed displacement hulls advancing in head seas with regular waves. An hybrid approach has been employed, solving the unsteady hydrodynamic problem in the frequency domain and the equations of motion in the time domain. A three dimensional Rankine panel method has been used in order to solve the hydrodynamic boundary value ...

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...

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...

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...
