Prevalence of parasite eggs (Strongyloides westeri, Parascaris equorum, and strongyles) and oocysts (Emeria leuckarti) in the feces of Thoroughbred foals on 14 farms in central Kentucky in 2003.

Abstract: Prevalence of internal parasites was determined by fecal examination for eggs and oocysts in Thoroughbred foals in central Kentucky in 2003. Fecal samples were examined from 733 foals on 14 farms. This included 70 trips to the farms and a total of 2,346 fecal samplings. Monthly collection of fecal samples was begun for four farms in February, six in March, three in April, and one farm in May. Termination of the study for all farms was the end of July. A criterion was that the foals be at least 10 days old for initial samplings. If available, the same foals were sampled each time, in addition to foals born in the interim between farm visits. Ages of the foals for the complete study varied from 10 to 223 days. Prevalence (mean %) was determined for eggs of Strongyloides westeri (1.5%), Parascaris equorum (22.4%), and strongyles (27.6%) and for oocysts of Eimeria leuckarti (41.6%) in feces of foals. Foals had infections of S. westeri on six farms (42.9%), of P. equorum on 12 farms (86%), and of strongyles and E. leuckarti on all 14 farms (100%).

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article discusses a study conducted in central Kentucky in 2003, which aimed to determine parasite prevalence by examining the feces of Thoroughbred foals for eggs and oocysts. The parasites in question were Strongyloides westeri, Parascaris equorum, strongyles and Eimeria leuckarti.

Study Design and Methodology

  • The study was conducted on 14 farms in central Kentucky in 2003 by collecting and examining the feces of Thoroughbred foals.
  • A total of 733 foals were included in the study, with the researchers making 70 trips to the farms and collecting a total of 2,346 fecal samples.
  • On four farms, monthly collection began in February, on six farms in March, three farms in April, and one farm in May. The study ended for all farms by the end of July.
  • The researchers ensured that the foals were at least 10 days old when the initial samplings were taken. If possible, the same foals were resampled throughout the study in addition to new foals born between visits.
  • The ages of the foals included in the complete study ranged from 10 to 223 days.

Results of the Study

  • Prevalence was determined by assessing the mean percentage of fecal samples containing eggs or oocysts from certain parasites.
  • The prevalence of Strongyloides westeri eggs was found to be 1.5%, while the prevalence for Parascaris equorum and strongyles was higher, at 22.4% and 27.6% respectively.
  • The highest prevalence found was for Eimeria leuckarti oocysts, present in 41.6% of the fecal samples.
  • Foals from six farms (42.9%) were found to be infected with Strongyloides westeri, whereas a larger number of farms (12 or 86%) had foals infected with Parascaris equorum. All 14 farms (100%) had foals with infections of strongyles and Eimeria leuckarti.
