Background: Aminorex, (RS)-5- Phenyl-4,5-dihydro-1,3-oxazol-2-amine, is an amphetamine-like anorectic and in the United States a Drug Enforcement Administration [DEA] Schedule 1 controlled substance. Aminorex in horse urine is usually present as a metabolite of Levamisole, an equine anthelmintic and immune stimulant. Recently, Aminorex identifications have been reported in horse urine with no history or evidence of Levamisole administration. Analysis of the urine samples suggested a botanical source, directing attention to the Brassicaceae plant family, with their contained GlucoBarbarin and Barbarin as possible sources of Aminorex. Since horsepersons face up to a 1 year suspension and a $10,000.00 fine for an Aminorex …

Background: Equine gastrointestinal nematodes (GINs) have been the subject of intermittent studies in Australia over the past few decades. However, comprehensive information on the epidemiology of equine GINs, the efficacy of available anthelmintic drugs and the prevalence of anthelmintic resistance (AR) in Australasia is lacking. Herein, we have systematically reviewed existing knowledge on the horse GINs recorded in Australia, and main aspects of their pathogeneses, epidemiology, diagnoses, treatment and control.

Methods: Six electronic databases were searched for publications on GINs of Australian horses that met our inclusion criteria for the systematic review. Subsets of publications were subjected to review epidemiology, …

This study was conducted to determine the effects of subanesthetic doses of ketamine given prior to premedication on the quality of anesthesia, recovery, and postoperative pain in horses. Eighteen horses were randomly recruited into three equal groups, S, LK, and HK, wherein saline, ketamine at 0.2 mg/kg body weight (bwt), and ketamine at 0.4 mg/kg bwt were given, respectively, i.v. for 30 min as a continuous rate infusion (CRI). Horses were premedicated with xylazine at 1 mg/kg bwt i.v. and butorphanol at 0.05 mg/kg bwt i.v. after 30 min. Anesthesia was induced using ketamine and midazolam and was maintained with …

This study was performed to characterize the coexistence of valvar insufficiencies of the mitral, tricuspid, aortic, and pulmonary valves and their possible association with atrial fibrillation in an equine clinic population. During an 11-year period, 348 horses had been examined for cardiac arrhythmias and suspected defects of the cardiac valves at the Vetmeduni Vienna, Austria. The study population included 256 male and 92 female horses. A subpopulation of 197 (57%) horses was identified with at least one valvular disorder. In these horses, mitral valve regurgitation (MR) was reported in 124 animals (63%), aortic valve regurgitation (AR) in 101 (51%), tricuspid …
