Nielsen MK, Baptiste KE, Tolliver SC, Collins SS, Lyons ET.Increasing levels of anthelmintic resistance in equine nematodes have led to recommendations of more sustainable anthelmintic treatment protocols with emphasis on parasite surveillance and diagnosis, rather than prophylactic calendar-based treatments. This requires knowledge of the diagnostic test performance of techniques for counts of eggs per gram of feces (EPG) as well as methods for culturing, counting and identifying third stage (L(3)) strongyle larvae per gram of feces (LPG). For horses, such information does not exist in the published literature. The aim of this study was to examine th...
Lyons ET, Tolliver SC, Kuzmina TA, Collins SS.Critical tests were performed in 2009 and 2010 in four 2-year-old horses naturally infected with internal parasites. The horses were from a herd (Farm MC) where reduced activity of ivermectin and moxidectin on small strongyles was demonstrated previously from EPG (eggs/gram of feces) data in field tests. Also, in critical tests in horses from the same herd, ivermectin was less effective on immature small strongyles in the lumen of the large intestine than when the drug was first marketed. The main interest in the present critical tests was to determine the efficacy of moxidectin (400 μg/kg) o...
Kim I, Cohen ND, Roussel A, Wang N.Gastric emptying studies are of great interest in human and veterinary medical research to evaluate effects of medications or diets for promoting gastrointestinal motility and to examine unintended side-effects of new or existing medications, diets, or procedures. Summarizing gastric emptying data is important to allow easier comparison between treatments or groups of subjects and comparisons of results among studies. The standard method for assessing gastric emptying is by using scintigraphy and summarizing the nonlinear emptying of the radioisotope. A popular model for fitting gastric emptyi...
Samper JC, Plough T.In the last decade, there has been a significant increase in the quality and commercial use of frozen equine semen. The emergence of new reproductive technologies, coupled with the high prices for an insemination dose from some stallions, the increasing costs of import and export and the marketing policies of stallion agents or owners in the sport horse industry has stimulated the fractionation of doses for insemination. Consequently, the sperm number and the volume of an insemination dose are significantly reduced. To deliver lower doses of sperm in lower volumes compared to the standard dose...
Kodama S, Maeda T, Mita H, Tamura N, Chiba K, Matsukawa M.Despite the prevalence of lower limb disease in racehorses, outdoor bone evaluation equipment is lacking. Consequently, a secure and cost-effective field screening system for bones is required to identify early-stage leg illness. Elastic stiffness cannot be measured using x-ray techniques and is closely associated with bone quality, which is recognized as a significant determinant of fracture risk. Quantitative ultrasound has garnered attention as a viable option, offering insights into elastic stiffness. Understanding the characteristic behaviors of ultrasonic wave properties (velocity, atten...
Taylor WTT.Many of the most important equine health problems - and their solutions - relate to the role of horses as a domestic animal, especially in riding and other kinds of transport. Recently, new discoveries from the archaeological sciences have rewritten our understanding of early horse domestication, suggesting that the first ancestors of domestic horses emerged in the Black Sea Steppes of western Eurasia at the turn of the second millennium BCE. This new chronology places horse domestication within a wider trajectory of early animal transport, including cattle and donkey, across western Asia and ...
