Contamination of the environment by strongylid (Nematoda: Strongylidae) infective larvae at horse farms of various types in Ukraine.
- Journal Article
Summary
This research investigates how differences in horse-keeping conditions affect the contamination level of environments like pastures, paddocks, and stalls by strongylid infective larvae (a type of parasitic worm) at horse farms, hippodromes, and riding clubs in Ukraine. The study reveals horses in different conditions show varying levels of infection, and it notes some seasons and areas are more prone to contamination.
About the study
- The study examined 1,237 horses from three different types of horse-keeping conditions: kept in stalls, kept in stalls/paddocks, or kept in stalls/pastures.
- The horses were based in various horse farms, hippodromes, and riding clubs across Ukraine.
- Through epidemiological studies, the contamination of stalls and grazing areas (such as pastures and paddocks) by strongylid larvae (L(3)) was analyzed.
- To understand the extent of contamination, grass and stall litter samples were examined using the Baermann procedure, a method for isolating nematodes from environmental samples.
Findings From The Research
- Horses kept solely in stalls presented the lowest levels of strongylid infection, with prevalence ranging from 46.4% to 77.8%, and infection levels ranging from 25.6 to 92.9 eggs per gram of feces (EPG).
- Horses kept in stall/pasture conditions showed the highest infection rate (prevalence of 95.1 to 100% and average infection 198.2-453.7 EPG).
- The larvae were found in the litter of all areas of the stalls, with the highest concentration noted at the stall center, the “toilet”, and entrance.
- The research observed a seasonal pattern, with the highest number of larvae found in stall litter during the summer months.
- It was also found that grass in paddocks was more contaminated with L(3) than permanent pasture grass (305.9-409.1 L(3)/kg compared to 86.3-161.4 L(3)/kg).
- The height of summer, specifically July, saw the highest levels of pasture grass contamination, with up to 970.7 L(3)/kg.
Conclusion
The results highlighted the significance of environmental contamination in the epidemiology of horse strongylidosis (a type of parasitic infection in horses caused by strongyles) in different horse-keeping conditions. This understanding could contribute towards improved management and treatment strategies for preventing horse strongylidosis.
