“…Moreover, macrocyclic lactones are able to eliminate tissue migrating larval stages of Parascaris spp. (Reinemeyer and Nielsen 2017 ; Lyons and Tolliver 2012 ; Lindgren et al 2008 ) and this property is expected to cause the better/longer lasting protection than pyrantel and fenbendazole, which are both only active against gut luminal stages of the parasite (Luksovsky et al 2013 ; Armstrong et al 2014 ; Lindgren et al 2008 ).…”

Gastrointestinal nematodes are ubiquitous parasites of grazing equines with Parascaris spp., and strongyles being the most relevant ones regarding the prevalence and potential disease severity. Despite their importance, epidemiological data regarding the presence and egg-shedding intensities of these parasites are scarce. Data from 1067 horse samples collected on German horse farms initially to compare diagnostic methods were used for epidemiological analyses. Due to its higher sensitivity, presence/absence data were based on a combined sedimentation/flotation technique while faecal egg counts were based on Mini-FLOTAC. For strongyles, 46.5% of the samples were positive and the median egg-shedding intensity was 40 (range 5–2590). In multivariate analyses, prevalence and egg-shedding intensity were significantly influenced by season, age group and sample type. The drug used for the last treatment and the number of foals on the yard only affected prevalence while the number of horses on the yard and sex were only significant for egg-shedding intensity. For Parascaris spp., a prevalence of 4.6% and a median egg-shedding intensity of 0 (range 5–905) were observed. In multivariate analyses, the age group, the time since the last anthelmintic treatment, presence and number of foals had significant effects on ascarid prevalence whereas egg-shedding intensity was significantly influenced by age group and season only. Parascaris occurred only on yards with foals, but with an increasing number of foals, Parascaris egg-shedding intensity decreased. Prevalence and egg-shedding intensity were influenced by different but partially overlapping variables for Parascaris and strongyles.

“…Foal owners should comply deworming instructions recommended by their own veterinarian. As a result from one study among foals, the use of combination therapy of ivermectinpyrantel against small strongyles and parascaris has been recommended (Luksovsky et al, 2013). Various drugs and drug combinations have been used among foals in Finland (Näreaho et al, 2011) and because of observed increase in anthelmintic resistance among horse population worldwide, it is recommended by Finnish veterinary practitioners that the efficacy of anthelmintic should be tested by taking fecal samples before and after the grazing season (Recommendation of Finnish Veterinary Practitioners, 2019; Horse Information Centre of Finland, 2019).…”

Foals are susceptible to many infectious diseases and they should be treated and protected differently compared to adult horses. Objectives of this study were to investigate vaccination and deworming practices of foal owners in Finland. The questionnaire study was executed. Foal owners (n = 236) gave a response and 217 of them told that they vaccinate their foals against equine influenza and tetanus (combination vaccine) (88 %) and herpes (12 %), but not against rabies (1,8 %). About 8 % did not vaccinated their foal at all and a risk of being non-vaccinated was regionally distributed (p<0,05). Among foal owners deworming (99,2 %) preferred over vaccination (92 %). Foals were dewormed by taking regular fecal samples first (76%), but also routine treatments without samples were favored (22 %). Differences between foals of this study and horse population in general (horses of all ages) need to take seriously when conclusions are drawn. Different recommendations come from different veterinarians should be taken under further research.
