Keywords: Karakalpakstan, helminth, helminthosis, sheep, nematode, extent of invasion, intensity of invasion Introduction In our Republic, special attention is paid to the development of animal husbandry, which is
one of the main branches of the agro-industry network.
In this regard, the development of animal husbandry on a scientific basis, aimed at
increasing the productivity of agricultural animals, improving the activities of the veterinary service
and ensuring epizootics, is defined as a special task. In the implementation of these tasks, it is
important to develop measures against the factors that have a negative impact on the development
of the livestock industry in our Republic and to put them into practice.
In most countries of the world, including our Republic, a number of research works have
been carried out by expert scientists to determine the species composition, biology, life processes,
ecology and systematics of productive animals, including sheep helminths, and to develop methods
of controlling the main helminthoses. But, despite this, the death of livestock, including sheep,
under the influence of helminth pathogens abroad, and the sharp decrease in productivity, and the
fight against them remain one of the urgent problems.
The purpose of the research work
is to study the species composition of the class of
nematodes distributed in the body of sheep in the Republic of Karakalpakstan and the level of
infection of sheep with nematodes.
Materials and methods. The research work was carried out in 2021-2022 in order to study
the nematode fauna of sheep in the regions of the Republic of Karakalpakstan. For this purpose,
mainly sheep of livestock farms and private households belonging to Kegeily, Karauzak,
Takhtakopir, Kungrat, Kanlikol, Amudarya, Turtkul districts of the Republic of Karakalpakstan
were subjected to helminthological examination.
During the research, 53 sheep were examined, of which 36 sheep were examined according
to Academician K.I. Scriabin’s complete method and 17 sheep were examined by incomplete
helminthological examination method [5]. In addition, 196 fecal samples were taken from sheep,
and they were studied based on G.A. Kotelnikov and other helmintocoprological methods [4].
In determining the species composition of helminths, attention was paid to morphological
signs, parasite localization, and literature on foreign and domestic helminthologists [1, 2, 3, 6] was
used.
