The research was held on ten rabbits of Large Grey breed, which were held on household farms of Poltava region. The diagnosing was complex: based on anamnesis data, clinical symptoms’ analysis, and the results of pathomorphological examination. The fragments of the liver, spleen, and kidneys were taken for histological analysis. While making histological analysis of the spleen it was revealed that lymphoid nodules were enlarged, some of them were of uniform structure, and others were in the state of hyperplasia. Non-uniformity of structure in addition to changing the size was registered in those nodules: there was less concentration of lymphoid cells in their central part and more concentration on the periphery. The situation was contrary in separate lymphoid nodules. The red pulp consisted of a large number of lymphoid cells and erythrocytes, the largest number of which were registered in the zones adjoining the places of lymphoid nodules’ location. Sometimes there were megakaryocytes in the field of vision. It was established, that blood filling of arteries was less than normal. In case of using some preparations, bilirubin inclusions were found at having big enlargements in red pulp. Grainy and fatty hepatocytes’ dystrophies, and also lymphohistiocytic interstitial hepatitis were also registered. At the same time, renal corpuscles were enlarged. Rather big spaces, filled with transparent substance containing vessel and cellular fragments (detritus), were revealed in the majority of them between glomeruli and the capsule.Capsule epithelial cells were destroyed in some places. Petechial hemorrhages were registered inside glomeruli. The destruction of separate podocytes and deep cells was noticed. The tubular epithelial cells were enlarged in size, and in some cases they were of cylinder, but not cubic shape; the spaces of such tubular were becoming correspondingly less. The epithelial cell cytoplasm of the tubular in some cases was not uniformand it was of cloudy-grey color: in other cases it had rather large colorless areas and, probably, looked like lipid inclusions (which were washed out from the cells as a result solvent impact during making histological preparations). Concentrations of eosinophilic masses (protein cylinders) sometimes containing certain amount of erythrocytes were often found in canaliculi spaces. Sometimes the destruction of epithelial cells was registered in the tubulеs, and their fragments were found in spaces. As a result of histological examination, the diffuse lymphohistiocytic infiltration in the renal interstitial tissue was found.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86213797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the widespread spread and severe toxic effects on animals and humans, the study of ochratoxins, the main producers of Aspergillus ochraceus and Pennicilium viridicatum, is intensively studied. The pigs are very sensitive to ochratoxins, the effects of which the most pronounced changes develop in the organs of the urinary system, as well as in the gastrointestinal tract, the liver, the immune and nervous systems. Diagnosis of ochratoxicosis should be comprehensive, based on anamnestic data, clinical, pathologoanatomical and chemico-toxicological studies. In the course of the study, the pathoanatomical changes that are developing in the body of sows for ochratoxicosis are studied in detail. Also, a mycological and mycotoxicological study was conducted in which the producer of ochertoxins Aspergillus ochraceus was detected in feeds. The content of ochratoxin A in feed fed to sows varied from 8.32 mg/kg to 85.72 mg/kg, and in the kidneys its concentration was 4.34–48.33 mg/kg. In a pathologoanatomical study in the kidneys, there was a discovery of gialinosis and sclerosis of renal glomeruli, as well as hyaline droplets degeneration, necrotic changes in epithelial proximal tubule, infiltration of interstitium by lymphocytes, macrophages, fibroblasts, focal growth of connective tissue, which was accompanied by the appearance of cystic cavities in 21.4% of animals. In the gastrointestinal tract, acute catarrhal or catarrhal-hemorrhagic inflammation was detected, and in 28.57% of sows the ulcers of the fundus zone of the mucous membrane of the stomach, the development of which was accompanied by massive hemorrhage in the gastrointestinal tract and posthemorrhagic anemia. Alterative (necrotic and degenerative changes) of hepatocytes, which were most pronounced in the periportal zone of the liver lobes, as well as acute congestive hyperemia, stasis in vessels of the microcirculatory bed, focal infiltration of the stroma by lymphocytes and histiocytes, were recorded in the liver.

One of the main characteristics of a biocide is its corrosive activity. The use of a biocide in a poultry house involves getting it on metal, rubber, plastic surfaces, and the like. The biocide should provide minimal aggressive effect on the surface data. In the industrial poultry industry, the most frequently used equipment with surfaces made of stainless steel, aluminum and galvanized iron. Also, when choosing a biocide, pay attention to its foaming properties. They should not exceed 40%, as this ensures a quality disinfection. One of the key points is the index of foam stability, which significantly affects the time of contact with the biocide and provides effective decontamination of the surfaces. The goal of the work. To determine the corrosion activity and foaming properties of the new domestic biocide “DezSan”. Materials and methods of research. In their experiments, a disinfection tool for the production of the scientific and production company “Brovаfarma” (Ukraine) “DesSan” was used. Relative corrosion activity of various concentrations of biocide “DezSan” was determined in comparison with the standard – 1.5% solution of sodium hydroxide. To determine the foaming properties of biocide “DezSan” used the method of Ross-Miles (1983). Results of research and discussion. The biocide “DezSan” in all experimented concentrations (0.25–1.5%) has a minor corrosion effect on aluminum, stainless and galvanized steel, compared with the standard (1.5% NaOH solution). The biocide “DezSan” does not cause deformation when exposed to metal samples. “DezSan” in various concentrations has a foaming property of 13.1 to 37.3%, which increased directly in proportion to increasing the concentration of biocides. The foaming capacity of “DezSan” did not exceed 40%, and the foam stability at these concentrations varied within 0,08–0,19. Conclusions and prospects for further research. Thus, the biocide “DezSan” has low corrosion properties in relation to aluminum, stainless steel and galvanized steel in comparison with the standard (1.5% solution of NaOH). The biocide “DezSan” does not cause deformation when exposed to metal samples. The foaming capacity was not more than 40%, and the foam resistance was up to 0.19. These indicators allow the wide use of biocide “DezSan” in the poultry industry.

Comparative anatomical, craniological and statistical methods of research were used. It was found that the scull of test animals is of a General anatomical structure (wide temporal fossa, a deep masseteric fossa, well-defined nuchal and external sagittal crests, the presence of angular process on mandible, relatively large tympanic bullas, underdeveloped lacrimal bone) and species differences (topography of split of the external sagittal crest, shape of mandibular angular process, the presence of intratympanical part of the temporal bone).

The solution of this problem is impossible only by increasing the production of livestock products, although this is the main source of their receipt. It is necessary to use additional, non-traditional types of raw materials containing full proteins, fats, vitamins, minerals and other biologically active substances necessary for the human body. One of these sources may be meat of food types of snails. It maintains a complex of replaceable and essential amino acids, vitamins, inorganic elements, carbohydrates and fats. The purpose of our work was to determine the content of fatty acids in cooked meat of the food species Helix pomatia, Helix aspersa maxima and Helix aspersa muller. This article presents the results of the content of fatty acids in meat of food snails using the method of gas chromatography. The presence and quantity of fatty acids is determined in three types of snails. In general, the meat of snails contains both saturated and unsaturated fatty acids. The composition of saturated fatty acids includes – kapron, palmithin, stearin, myristic, arachin, capryl, laurin, begen, kaprin, heptadecanova. From unsaturated fatty acids, snail meat contains omega-3, omega-6, oleinic, palmitoleic, linoleic, arachidonic, linolenic, cis-5,8,11,14,17-eicosapentaenoic, cis-11,14-eicosadenic, cis-13,16-doceta-adenoic, docosapentaenoic. As a result of our research on the content of fatty acids in cooked meat of snails, we found that the mass fraction of 11 unsaturated fatty acids – oleinic, palmitoleic, linoleic, omega-3, omega-6, arachidonic, linolenic, cis-5,8,11, 14,17-eicosapentaenoic, cis-11,14-eicosadenic, cis-13,16-doceta-adenoic, docosapentaenoic to a mass fraction of 10 saturated fatty acids is significantly different in each type of snail. Thus, the mass fraction of saturated to unsaturated fatty acids is in the meat of Helix pomatia, Helix aspersa maxima, Helix aspersa muller 1:5.73; 1:5.05 and 1:4.81 respectively. Most of all, unsaturated fatty acids are found in boiled meat of Helix pomatia snails and amount to 126.77% to the sum of fatty acids, and saturated – in the boiled meat of Helix aspersa muller snails – 24.86% to the sum of fatty acids. Useful and well-known all fatty acids ω-3 and ω-6 enriched boiled meat of Helix aspersa maxima snails – 49.06% to the sum of fatty acids, while Helix pomatia and Helix aspersa muller are 48.81 and 44.35% to the amount of fatty acids, respectively. It should be noted that the total content of fatty acids in the meat of snails varies in the following limits: Helix pomatia snails 148.89, Helix aspersa maxima 149.11, and Helix aspersa muller 144.4.

A pathoanatomical study was conducted; samples of the frontal area of the cerebral cortex of cats, which were fixed in a 12% aqueous solution of neutral formalin, a solution of Carnoua and 96° ethyl alcohol, were selected. The histocuts were made, which were stained with hematoxylin and eosin, thionine for Nisslem. In order to detect the astrocytic glory, a fraction of the cerebral cortex was fixed by the Golgi-Clatzo method with a fresh mixture of chloral hydrate-formalin-bichromate and produced histocuts on a freezing microtome. For histological examination of the cerebral cortex of cats, changes in the non-inflammatory character were observed, which were characterized by disorders of hemomycrocycle circulation, edema and degenerative processes of the neuroglial complex and neurons. Violations of the structural organization of endothelial cells, basal membranes of capillaries and venules should be considered as an important indicator of functional changes in tone, permeability of the microcirculatory channel, which contributed to the development of perivascular and pericellular edema, which in its turn led to regressive changes of glial elements; acute swelling of neurons with the formation of microcavities in nuclei; a sharp decrease in the content of the chromatophilic substance in pyramidal and stellate cells; the development of gidropic dystrophy in star cells and creatures; rise of shadow cells.

For pathomorphological studies, animals were selected with clinical signs of active PCV2‑infection (in 1 ml of whole blood of which contained more than 107 copies of the PCV-2 virus equivalent gene) and also piglets with positive optical density of specific antibodies (Ig G and Ig M) in serum blood. Pathomorphological changes were characterized by gradual exhaustion of the lymphoid parenchyma with a sharp decrease in the area of the cortical substance of the particles. Against the background of the degradation of the lymphoid parenchyma of the organ, there is a tendency to increase the relative area of the interstitial connective tissue, as well as the absolute size and number of thymic bodies, has been established.","PeriodicalId":21677,"journal":{"name":"Scientific Messenger of LNU of Veterinary Medicine and Biotechnology","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83345003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
