Prevalence of infestation with gastrointestinal nematodes in Pony Club horses in Victoria.

This study looks at the amount and types of gastrointestinal nematodes, which are a type of parasite, found in horses that belong to Pony Clubs in Victoria, Australia. The research also tries to assess what factors might determine the rate of these parasites.

Research Aims and Methodology

• The aim of the study was to identify the most common parasitic nematodes in the digestive system of Pony Club horses in Victoria, Australia, determine how common infestation with these parasites is, and identify any factors that might indirectly impact nematode parasitism.
• The researchers enrolled a total of 106 horses from five different Pony Clubs located in outer Melbourne and Geelong, Victoria, in Australia.
• The team collected fresh faecal samples and carried out faecal egg counts (FECs) within 2 hours from the collection time.

Study Results

• The FECs varied between 0 and 3750 eggs per gram (epg) with an average count of 422 epg.
• The eggs were found in the faeces of 52% of the tested horses, with an average count of 813 egg per gram.
• Counts of 500 epg or higher were shown in 27% of the tested horses.
• Factors such as the Pony Club to which the horse belonged, the season and the sex of the horse did not seem to have any connection with the FEC.
• Within the group of horses that received anti-parasite treatment 8 weeks or less before the sampling, FECs were often 50 epg or more, and high FECs were also quite common.

Conclusions from the Study

• The study results show that the efficacy of treatment is generally low and/or reinfection occurs soon after treatment.
• The study also reveals that current management of internal parasites is not efficient enough to prevent high FECs among Pony Club horses in Victoria.
