“…Similarly, grass samples were collected by "W" shaped sampling method in every month from common grazing areas of the selected villages. Pasture larval burdens (PLB) were assessed as per Swarnkar et al (2008). These were compared with the bioclimatograph prepared as above to see if the same has any relationship between the availability of Haemonchus spp.…”

“…Gastrointestinal parasitism is one of the most pervasive challenges to the health and welfare of ruminants (Swarnkar and Singh 2015). Bioclimatographs, descriptions of the climatic envelope in which disease occurs, have been developed to predict outbreaks of soil transmitted helminthes in domesticated animals Singh 2011, Bonnell et al 2016).…”

Based on a systematic epidemiological study, bioclimatographs were prepared for Haemonchus and Trichostrongylus spp. infecting goats of subtropical high humid zone of Sikkim, India. Three meteorological parameters i.e., maximum and minimum temperature, average relative humidity and total rainfall were recorded for each month from April 2012 to March 2013 and correlated with faecal egg count, faecal larval count and pasture larval count of grazing area under investigation. Bioclimatographs were prepared against different meteorological parameters and the predicted values were correlated with actual field study. The findings in goats revealed higher rate of infection of Haemonchus and Trichostrongylus spp. from July to October and September to early March and higher intensity from June to October and November to February, respectively. The higher incidence of infection of larval stages on pasture was observed from June to October for Haemonchus spp.The prediction or forecasting of Haemonchus spp. and Trichostrongylus spp. infection in goats of this agroclimatic region as per bioclimatographs revealed a prediction for development and survival of eggs and larvae of Haemonchus spp. infection from July to October and for Trichostrongylus spp. from September to February. Bioclimatographs revealed that maximum temperature (Tmax.) v/s total rainfall (TRF) and Tmax. v/s relative humidity (RH) gave better prediction for Haemonchus spp, while for Trichostrongylus spp. it was minimum temperature (Tmin.) v/s RH.

Sheep farming is a universal industry that supplies mutton, by-products, milk and wool, ranks third place in the world by statistical indicators and belongs to the economically sound livestock industries. However, along with the significant benefits, the industry has risks connected with a large number of diseases of parasitic etiology, among which one the relevant place belongs to diseases, caused by the nematodoses of the digestive canal. The epizootic situation concerning the nematodoses of the digestive canal was studied in the farms of the Central and SouthEastern regions of Ukraine (Zaporizhia, Kyiv and Poltava regions) during 2015-2019. Coprovascopic investigations were performed on sheep of different breeds and age groups using the McMaster quantitative method, determining the magnitude and intensity indicators of the invasion. The investigations have shown a significant spread of nematodes of the gastrointestinal tract of sheep in the Central and SouthEastern regions of Ukraine. The average invasion extensiveness was 45.92 % for intensity from 50 to 2350 eggs/g of fecal. As a result of the conducted coprological investigations, the parasitism of nematodes of the series Strongylida (Railliet et Henry, 1913), Trichurida (Skrjabin et Schulz, 1928; Spassky, 1954), Rhabditida (Chitwood, 1933), were registered on the morphological characteristics of eggs isolated from fecal of diseased sheep. In percentage terms, the strongilatosic invasion was the most widespread in the territory of the investigated region and reached 44.08 % of the total number of sheep with nematodoses deseases of the digestive canal. Accordingly, the trichuriasic and strongyloidosic infestations of sheep were recorded slightly less, with a share of 31.32 % and 24.60 %, respectively. In the cross-section of the investigated regions, it was fixed that the greatest quantity of the sheep ill of the digestive canal nematodoses were detected in the sheep farms of Poltava region (EI = 54.27 %). The animal farmings of Kyiv (EI = 48.79 %) and Zaporizhia (EI = 38.21%) regions were more fortunate. The conducted investigations for the first time in Ukraine have elucidated the present epizootic condition with regard to nematodoses of the digestive canal of sheep. The prospect of further investigations is to study the fauna of the nematodes of the sheep alimentary canal of the territory of the Central and SouthEastern regions of Ukraine by the consequences of complete helminthological autopsy of the digestive tract organs.

Nematodoses of the sheep’s digestive tract is distributed both in Ukraine and abroad. Pathogens of these diseases in the form of monoinvasions, as well as associative with other invasive diseases, cause sheep farms considerable economic losses. Systematic monitoring studies that are carried out to establish a helminthofauna specific to a particular region are a key to successful control of parasitic diseases. Information on the species composition of pathogens causing invasive diseases in animals in the territory of a certain region, allows us to conduct scientifically based selection of drugs and to conduct effective, cost-based treatment and prevention measures. Therefore, the purpose of our research was to establish the distribution of nematodoses of the digestive canal of sheep and their peculiarities in the conditions of sheep farms in the territory of the Kyiv region (Central region of Ukraine). The research was conducted in conditions of sheep farms in the Kyiv region (Baryshivka, Bila Tserkva, Zghurivka, Pereiaslav-Khmelnytskyi, Skvyra, Tarashcha, Fastiv and Yahotyn districts). Helminthoscopy of fecal samples was performed using the McMaster’s method. As a result of scatoscopy diagnostics of sheep, a considerable distribution of nematodoses of the digestive canal was established on the territory of the Kyiv region (the severity of the invasion was 48.79 %). According to the morphological features of eggs isolated from faeces of sick animals, parasitization of nematodes from three sequences was established: Strongylata (38.98 %), Trichocephalata (33.36 %), and Rhabditata (27.66 %). It was registered that the sheep farming of the Bila Tserkva, Yahotyn and Zghurivka districts (EI – 61.49, 59.73 and 54.17 % respectively) were the most unfavorable for nematodoses of the digestive tract. The disease was registered in the form of both mono- and mixinvasions. The associative course of diseases (75.03 % of the total number of diseased animals) was dominant with two-, three-, four-, and five-component associations of sheep parasite pathogens (47.63, 35.47, 11.50 and 5.40 % in accordance). It has been established that nematodoses of the digestive canal of sheep (strongylates of the digestive canal, strongyloides and trichiuruses) are in the composition of mixinvasions, the sympathizers of which are: eimeries, moniezies, and melofagoses in various combinations. Key words: nematodoses, strongylatoses of the digestive canal, trichiuruses, strongyloides, scatoscopy research.
