ENDOPARASITES OF VIETNAMESE BELLIED PIGS IN THE PASTURE GROWING SYSTEM IN FARMS OF THE ODESA REGION

Abstract

The article provides data on the spread of endoparasitoses in vietnamese bellied pigs in the pasture growing system in the farms of the Odesa region. Pigs can have numerous intestinal parasites, most often protozoa and nematodes. Although the course of such parasitic infections is usually subclinical, clinical manifestations may occasionally occur, especially in growing pigs. The study of the structure and functioning of parasitic systems is extremely important. The obtained data on gastrointestinal parasites in pigs can help in the development of effective and sustainable measures for the prevention of pig diseases. The aim of the work was to monitor endoparasitoses in vietnamese bellied pigs in the pasture growing system, depending on age, in the farms of the Odesa region. A total of 475 samples of feces of vietnamese bellied pigs from 6 private farms of Odesa region were studied. Fecal samples were collected from suckling piglets and weanling piglets (<4 months), young (4‒8 months) and adults (>8 months) of both sexes. It was established that the total infestation with protozoa in piglets < 4 months. age was 86.7 %, in growing pigs (4-8 months) ‒ 28.9 %, and in adults ‒ 18.7 %, helminthes infestation was 13.3 %, 71.1% and 81.3% in accordance. Piglets < 4 months. age, Isospora suis (28.3 %) and Eimeria suis (18.6 %) were most infested, while Strongyloides sp. (2.7 %). Ascaris suum (33.4 %) and Trichuris suis (24.6 %) had the highest lesion extent in growing pigs (4‒8 months), and the lowest among protozoans was Isospora suis and Blastocystis sp. (2.9 %). In adult pigs, the highest infestation of Ascaris suum (34.4 %) and Trichuris suis (31.2 %) was recorded, while isosporosis and cryptosporidiosis were not recorded.
