Transmission of some species of internal parasites in horses born in 1990, 1991, and 1992 in the same pasture on a farm in central Kentucky.

Abstract: Studies were conducted on transmission of natural infections of several species of internal parasites in horses born and kept on the same pasture on a farm in central Kentucky. Data for the first year (1989) of a 4 year study on this farm have been published recently. The present research represents the second (1990), third (1991), and fourth (1992) years of the investigation. The number of animals (n = 28) examined varied from eight born in 1990 to ten each born in 1991 and 1992. For each year, examination was made of one horse per month, beginning in June of the year of birth and extending through January (1990) or March (1991 and 1992) the following year. Ages of the horses at necropsy ranged from 87 to 251 days. Major parasites present and months of recovery were: bots--Gasterophilus intestinalis in the mouth September-January and in the stomach August-March; stomach worms--Trichostrongylus axei in August and November, Habronema spp. (immature) in July-November and January, and Habronema muscae in October, January, and February; ascarids--Parascaris equorum in the small intestine and lungs all months; intestinal threadworms--Strongyloides westeri in all months except February; large strongyles--Strongylus vulgaris in the large intestine in all months except July and August and in the cranial mesenteric artery in all months, and Strongylus edentatus in the large intestine in January and in the ventral abdominal wall in all months; pinworms--Oxyuris equi in June and January-March; tapeworms--Anoplocephala perfoliata in August-October and December-March; and eyeworms--Thelazia lacrymalis August-February. Yearly differences and similarities of infections in the horses are discussed. The value of this type of research is mentioned.

The research explores the transmission of several species of internal parasites in horses that were born and raised in the same pasture in central Kentucky between 1990 – 1992.

Study Objective and Procedure

  • The objective of the research was to study the natural transmission of various species of internal parasites in horses. The test subjects were all born and raised in the same pasture on a farm in Kentucky.
  • This study represents the second, third, and fourth years of an ongoing investigation, with the first year’s data having been previously published.
  • The number of horsed examined was 28, with eight born in 1990 and ten each in 1991 and 1992.
  • Examinations were performed monthly on one horse, starting from June of the birth year and extended to January (1990) or March (1991 and 1992) of the following year.

Findings of the Study

  • The ages of the horses at the time of necropsy ranged from 87 to 251 days.
  • Several species of parasites were present including Gasterophilus intestinalis or bots, stomach worms such as Trichostrongylus axei and Habronema spp., ascarids like Parascaris equorum, intestinal threadworms (Strongyloides westeri), and Strongylus edentatus, among others.
  • Different parasites were found at different times of the year; for example, Gasterophilus intestinalis was found in the mouth from September to January and in the stomach from August to March.
  • Regardless of the year the horse was born, some types of parasites remained constant. For instance, Parascaris equorum was found in the small intestine and lungs in each month.

Implications of the Study

  • The study presents valuable insights into the transmission and lifecycle of various species of internal parasites in horses. This could lead to better preventive strategies to ensure the health of horses.
  • The differences and similarities in parasite infection observed annually in the horses were discussed, hinting towards the possible influence of environmental changes on the parasite transmission.
  • The study also underlines the value of such comprehensive research in animal health to control and manage parasite infections more effectively.
