EPIZOOTIC SITUATION REGARDING HELMINTHIASES OF WATERFOWL ON FARMS OF SUMY REGION

Abstract

Helminthiases have been and remain an unsolved problem on poultry farms. Waterfowl, regardless of the
natural and climatic characteristics of farms’ location, is affected to different degrees by various types of
helminthes. The method of keeping, the frequency of anti-helminthic treatments, and the density of the livestock,
affect the species characteristics of helminthiases. With the combined course of helminthiases, the
economic losses from infections grow. Accordingly, the knowledge of their nosological profile is the first
stage in the development of effective schemes for the prevention of helminthiases. The purpose of our work
was to find out the spreading of geese helminthiases on household farms of Sumy region, to establish the
prevalence and intensity of the invasion, the seasonal dynamics of helminthiases manifestation among the
poultry. To achieve the goal, the coproovoscopic study of geese feces was carried out and their species characteristics
were determined. According to the results of the studies, the spreading of geese helminthiases was
established on household farms in Sumy region and a clear seasonal dynamics of their manifestation was
noted. The peak of infestation with helminthiases was recorded in summer and autumn. During this period,
the maximum prevalence of infection by the following identified species of helminthes was established: amidostomas
(85.4 %), ganguleterakisas (52.0 %) and trichostrongyles (36.0 %). The tendency towards a decrease
in the prevalence of the infection in the spring was determined. EI for amidostomosis was 26.3 %, for
ganguleterakosis – 32.4 % and trichostrongylosis –4.7 %. II at amidostomosis and ganguleterakosis reached
the maximum in the autumn: 3.48±0.61 and 4.04±0.62 specimens/ drop of flotation liquid, respectively. At
the same time, the peak of II at trichostrongylosis was during the winter period – 3.22±0.36 specimens/drop
of flotation liquid. Helminthiases are an urgent problem for private farms in Sumy region. In the nosological
profile of helminthiases, the causative agents of amidostomosis, ganguleterakosis, and trichostrongylosis
were identified during the study period.
