Monitoring of the epizootic situation regarding trichurosis of sheep in the Poltava region

Abstract

Sheep breeding is a branch of animal husbandry that is unique in terms of the variety and specificity of products. Sheep can utilize feed resources that are almost inaccessible to other types of farm animals. One of the factors in increasing the efficiency of sheep breeding is ensuring the well-being of farms concerning invasive diseases, particularly trichurosis. Successful control of trichurosis in sheep farms is the most effective for monitoring and forecasting the development of the epizootic situation depending on the climate-geographical zone. The work aimed to monitor the epizootic situation regarding sheep trichurosis in the Poltava region. According to the analysis of the statistical data of the reporting documentation of the Main Department of the State Production and Consumer Service in the Poltava region for 2018–2022, it was established that the share of helminthiasis among diseases of infectious etiology of sheep reaches 99.6 %. At the same time, among helminthiasis, nematodes have the highest specific weight – 69.0 %, and trematodes were less common – 31.0 %. Strongyloidiasis (68.05 %) was diagnosed most frequently among helminth infections during the studied period. A smaller percentage was strongylidosis of digestive organs (17.16 %) and trichurosis (11.24 %). Dictyocaulosis was rarely diagnosed among livestock (3.55 %). The average extent of trichurosis infestation of sheep during the investigated period in the territory of the Poltava region was 7.51 %, ranging from 5.83 to 9.26 %. Indicators of the extent of trichurosis invasion ranged from 5.45 to 33.33 % by area. According to the results of coproovoscopy, the highest values of sheep infestation with Trichuris were found in the farms of Karliv and Mashiv regions – 33.33 and 20.0 %, respectively. Less often, trichurosis was diagnosed in sheep farms of Dykanskyi (8.0 %), Reshetylivskyi (6.67 %), and Kotelevskyi (5.45 %) districts. The obtained data from monitoring studies prove the relevance of the further and more in-depth analysis of the spread of trichurosis infestation among sheep in the territory of the Poltava region, taking into account the age and seasonal dynamics of the disease, as well as the peculiarities of its course as part of mixed infestations.
