Abstract

Analysis of the influence of horsekeeping conditions by contamination of the environment pastures paddocks and stalls by the strongylid infective larvae L3 was carried out at various types of horse farms hippodromes and riding clubs in Ukraine A total of 1237 horses from three types of horsekeeping conditions were examined Epidemiological studies of stall and grazing area pasture and paddocks contamination by L3 were performed at hippodrome stalled horsekeeping and horse farms with stall/paddockkeeping and stall/pasturekeeping conditions Grass and stall litter samples were examined by the Baermann procedure It was found that horses of stallkeeping conditions had the lowest level of strongylid infection prevalence 464–778 average infection 256–929 eggs per gram of feces EPG and lowest proportion of large strongyle L3 in coprocultures 16–113 Horses of stall/pasturekeeping conditions were the most infected prevalence 951–100 average infection 1982–4537 EPG and the proportion of large strongyle L3 was 173–247 Strongyle L3 were found in litter of all parts of individual stalls areas at the stall center “toilet” and entrance were the most contaminated The highest L3 number in stall litter was registered in summer Contamination of permanent pasture grass by L3 was notably lower than grass in paddocks 863–1614 L3/kg compared with 3059–4091 L3/kg The highest level of pasture grass contamination was observed in the middle of summer July—up 9707 L3/kg The results obtained confirmed importance of environmental contamination in epidemiology of horse strongylidosis at various types of horsekeeping conditionsAuthor thanks Oleksandr Starovir MS from the National Agricultural University for his assistance in experiments at the Kyiv state hippodrome Dr Igor Dzeverin PhD from the Institute of Zoology NAS of Ukraine for his consultations on statistical processing of the results and Dr Iurii Yuriy Kuzmin PhD for his remarks and comments on the text Author also thanks Dr Sharon Tolliver MS and Dr Eugene T Lyons PhD from Department of Veterinary Science University of Kentucky Maxwell Gluck Equine Research Centre Lexington for their valuable help in the manuscript revising
