Abstract
The presented study aimed to denote the parasitic infection in 630 equine animals during one year (Feb. 2008 to Jan. 2009).As well as seasonal variation of the detected parasites and the relationship between sexes and ages of the animals were investigated.Fecal cultures was done to determine the different Strongylids larvae.in addition, the effectiveness of the chemical anthelimintic (Albendazole) and Equiveen past was examined in comparison with the natural anthelimintic (Propolisand artimisia) The obtained data revealed that, the total infection rate of parasitic infection of equines was 81.38%, and for donkeys, horses and mules were 90%, 62.3% and 40%, respectively and donkeys were harboured the most of detected parasites.Fecal samples examination revealed that (81.38%) of 650 animals were infected by at least one of the following helminthes : Fasciola spp. G. aegyptiacus, Anoplocephala spp., Strongylids spp., Strongyloides westeri, P. equorum and D. arnfieldi.The results revealed that, donkeys had high incidence of helminthes than horses and mules.The incidences of helminthes in donkeys were 4.56% for Fasciola spp., 3.91% for G. aegyptiacus, 8.26% for Anoplocephala spp., 64.13%for Strongylids, 1.08% for S. westeri, 4.78% for P. equorum nt) and 3.26% for D. arnfieldi.The incidence of helminthes in horses were 1.14% for Fasciola spp. and G. aegyptiacus, 5.07% for Anoplocephala spp., 39.04% for Strongylids (14.85% for P. equorum, and they were free from S. westeri and D. arnfieldi infections.Mules were infected only with Strongylids (40%) and they were free from Fasciola spp., G. aegyptiacus, Anoplocephala spp., S. westeri, P. equorum and D. Arnfieldi.By fecal culture, we differentiated between the larvae of Strongylus and found 76% Strongylus vulgar 6%, S. equines, 4% Strongylus edentus and 14% Triodontophorus.Concerning the season, the prevalence of equine parasites in donkeys, Fasciola spp. G. aegyptiacus, Anoplocephala spp. and Strongylid spp. were found in all seasons, P. equorum and D. arnfieldi were absent in spring and autumn, respectively, while S. westeri was detected only in summer and winter.In horses, Fasciola spp. and G. aegyptiacus were detected only in summer and winter, respectively, while Anoplocephala spp., Strongylid spp. and P. equorum were detected in all seasons. The unique helminthes, Strongylid spp. was found in mules and prevailed only during winter and spring.In respects to relationship between ages of examined equine and parasitic infection the obtained data revealed that, adult donkeys was more susceptible to infection than other ages by Fasciola spp., G. aegyptiacus, Anoplocephala spp., Strongylids, P. equorum and D. arnfieldi, while young ages for S. westeri.Adult horses were susceptible for G. aegyptiacus, Anoplocephala spp., Strongylid spp. and P. equorum, also older ones were susceptible for Fasciola spp. and Strongylid spp. Old mules were prone for Strongylids spp. infection.With respect to the relation between sexes of examined equines and parasitic infection it was found that both male and female donkeys were infected by Fasciola spp., G. aegyptiacus, Anoplocephala spp., Strongylids spp., S. westeri, P. equorum and D. arnfieldi.Also in horses Anoplocephala spp., Strongylids spp. and P. equorum were detected in both sexes.While Fasciola spp. was detected in male horse only and G. aegyptiacus in female only. Strongylids spp. was detected in both male and female mules.All infected donkeys by Fasciola spp. and P. equorum had low parasite burden (< 500 worm/ animal).Albendazole 10% was given in the dose of 1 ml/15 kg bw as one dose.was revealed that reduction percent 100%. Equiveen was given at the rate of 40 mg\kg bw revealed the reduction% after 6 days from treatment97.5%.The effectiveness of propolis against the gastrointestinal parasites of equines the reduction % was at 12 days after start treatment was 83.7%. Artemisia revealed the reduction percentage was 79%.The fecal examination revealed that the egg count of the Albendazole treated group was reduced by 100%% in the after 3rd days treatment.In the Propolis treated group, there were no significant changes except in the 12th days after the last dose of treatment.Equiveen paste gives result after 6 day reach97.05% artemisia extract gives result after 7 day was 79%.
