Abstract

Formulation of the problem. Sheepbreeding – one of the most universal and promising sectors of animal breeding, which is important, and in some cases the only source products such as wool, lamb, milk, fur, leather sheepskin skin coat and so on. The most important characteristic of sheep is their adaptability to different conditions of breeding and the ability to use the cheapest food. Significant economic damage to the sheepbreeding industry cause the intestinal helminthiases, including the leaders – strongylatoses of digestive system. Published data indicate that chabertiosis of sheep are distributed in different natural-climatic regions around the world. Thus, the study of population and fauna of parasites of sheep, their features morphometrical structure that characterizes their properties to adapt and parasitism, has both theoretical and practical importance. The purpose of research – to study morphological and metric indicators of nematodes species Chabertia ovina, isolated from sheep intestines. Materials and methods. Research conducted during the winter period 2016–2017 on the basis of Scientific Laboratory of Department of Parasitology and Veterinary Expertise Faculty of Veterinary Medicine of Poltava State Agrarian Academy. Investigated 10 intestines of sheep that came from the slaughter points of Poltava region. We used the methods of complete helminthological autopsy complete different parts of the intestine by K. I. Skriabin. Results and discussion. Conducted studies have established that helminths were found relating to species Chabertia ovina, found them only in the large intestine in 100 % of cases. Morphologically outside nematodes of thise species is white and thick, opaque. The females rear end has a black color. Value of selected males and females is 1:1, and the average length respectively 15.65±0.52 and 20.1±0.42 mm. A characteristic feature of the structure of the head end chaberties is the presence of globular, thick-walled, large oral capsules. Established significant morphological features of the structure of the tail ends of females and males Ch. ovina. Conclusions. 1. Chabertiosis of sheep caused by nematodes of species Chabertia ovina, localized in the large intestine, and is widespread in Poltava region (EI – 100%). 2. To morphometric characteristics of species Chabertia ovina can be attributed indicators the length and width of males and females, structure and size of the esophagus, oral capsule and the rear end of the body, the size of eggs. Prospects for further research. Appropriate further research is to determine relationships of chaberties relationships with other pathogens of intestinal strongylates in the body infested sheep.
