Käesoleva töö eesmärgiks oli selgitada sigade siseparasiitide levikut meie tingimustes,
nakatumise seoseid pidamistingimustega ja antiparasitaarsete preparaatide kasutamist.
Eesmärgiks oli selgitada Eesti sigalates nii invasiooni ekstensiivsust kui ka invasiooni
intensiivsust erinevate parasiidiliikidega sigade vanusegruppide kaupa.
Kasutati flotatsioonimeetodit, mille põhimõte seisneb selles, et uuritav roe segatakse vedelikuga,
mille erikaal on helmintide munade ja koktsiidide ootsüstide erikaalust suurem.
Tsentrifuugimisel kasutati NaCl küllastatud vesilahust (erikaal 1,18–1,20). Parasiitide munade
leidmiseks kasutati mikroskoobi 80–100 × suurendust.
Koproloogilised uuringud viidi läbi neljas sigalas, kus oli kokku 9165 siga. Uurimiseks võeti 601
koproproovi. Kõik uuritud sigalad paiknesid Eestis ja kuulusid nelja erinevasse maakonda:
Sõmeru AS Järvamaal, Puurmani Jõgevamaal, Ilmatsalu Tartu maakonnas ja Samirte OÜ
Harjumaal. Kõik uuritud farmid olid suurfarmid, kus igaühes ulatus sigade üldarv üle 1000.
Uuringud näitavad, et enamlevinud helmindid olid Ascaris suum ja Oesophagostomum spp.
Esimesed askariidide ja ösofagostomumide munad leiti 2–3 kuu vanuste põrsaste
populatsioonides. Invasiooni ekstensiivsus kasvab põrsaste vanuse suurenemisega: sigade
soolenakkuste riskigrupp on 2–3 kuu vanused võõrdepõrsad ja kõige rohkem nakatunud olid
4–6 kuu vanused nuumikud. Vanemaealistes emiste ja kultide gruppides hakkas askariidide ja
ösofagostomumide mune eritavate sigade protsent järsult langema.
The purpose of this research was to determine the distribution of swine endoparasites in our conditions, the connection between parasitic invasions and animal husbandry and the use of antiparasitic drugs. The aim of the work was to explain the invasion extensity as well as the invasion intensity in different endoparasite species in different animal age groups on Estonian swine farms. The flotation examination method was used. The principle of this method is to mix faecal sample with flotation fluid which relative density is larger than Ascaris suum and Oesophagostomum spp. eggs relative density. In centrifuge saturated saline solution (NaCl, relative density 1.18-1.20) was used. To find endoparasite eggs the microscope (enlargement 80-100×) was used. The coprological examination was conducted in four swine farms, where were 9165 pigs. A total 601 faecal samples were examined. All studied swine farms are situated in Estonia and have been chosen from different districts: Sõmeru AS in Järvamaa, Puurmani in Jõgevamaa, Ilmatsalu in Tartu district and Samirte OÜ in Harjumaa. All four farms were large farms with more than 1000 pigs in everyone. The research results are showing that the most commonly found endoparasites were Ascaris suum and Oesophagostomum spp. Firstly A. suum and O. spp. eggs were found in 2–3 month old piglets. The invasion extensity is growing with the piglets aging. The most severe intestinal contagion was in 5–6 month old fatted groups, but the percentage of A.suum and O.spp. eggs began markedly decrease in older swine.
